HP ProLiant DL380p Gen8 Server Review

As StorageReview expands our enterprise test lab, we're finding a greater need for additional latest generation servers (like the HP D380p Gen8); not just from a storage perspective, but from a more global enterprise environment simulation perspective as well. As we test larger arrays and faster interconnects, we need platforms like the HP DL380p to be able to deliver the workload payload required to these arrays and related equipment. Additionally, as PCIe storage matures, the latest application accelerators rely on third-generation PCIe for maximum throughput. Lastly, there's a compatibility element we're adding to enterprise testing, ensuring we can provide results across a variety of compute platforms. To that end HP has sent us their eighth-generation (Gen8) DL380p ProLiant, a mainstream 2U server that we're using in-lab for a variety of testing scenarios.


While some may wonder about the relevancy of reviewing servers on a storage website, it's important to realize how vital the compute platform is to storage performance, both directly and indirectly. When testing the latest PCIe Application Accelerators for example, for maximum throughput, it's critical to make sure compute servers are ready in areas ranging from hardware compatibility, performance scaling and saturation, to even often overlooked elements like how a server manages cooling.

Case in point, most 2U servers use riser boards for PCIe expansion, and knowing what drives those slots is just as important as the slots themselves. If one 16-lane PCIe slot is being shared for three slots, those may under-perform compared to a solution that uses two 16-lane PCIe slots to share between three riser slots. We also have an eye toward how well manufacturers make use of the cramped real-estate inside 1U and 2U servers, as all are not created equal. Items in this category can vary from everything from cable management to how many features are integrated versus requiring add-on cards, leaving PCIe expansion entirely open to the end-user instead of utilizing those slots for RAID cards or additional LAN NICs. Even the way server vendors handle the traditional SATA/SAS bays can be vastly different which could be the difference between an ideal server/storage relationship and one that is less desirable.

The HP ProLiant DL380p Gen8 Server series is comprised of 2U, 2-socket compute servers that feature a Smart Array P420i RAID controller with up to 2GB Flash Backed Write Cache (FBWC), up to five PCIe 3.0 expansion slots and one PCIe 2.0 expansion slot, and extensive built-in management capabilities. Our server accepts small form factor (SFF) 2.5-inch SAS, SATA, or SSD drives, while other configurations of the ProLiant DL380p Gen8 servers accepting large form factor (LFF) 3.5-inch drives are also available.

Our HP ProLiant DL380p Gen8 Specifications:
  • Intel Xeon E5-2640 (6 core, 2.50 GHz, 15MB, 95W)

Hardware Options

The DL380p Gen8 series features configurations with up to two Intel Xeon E5-2600 family processors, up to five PCI-Express 3.0 expansion slots and one PCI-Express 2.0 slot (three with single CPU, six with dual CPU). The standard riser configuration per CPU includes one x16 PCIe 3.0 slot, one x8 PCIe 3.0 slot, and one x8 PCIe 2.0 slot. HP offers different configuration options, with an optional riser that supports two x16 PCIe 3.0 slots. The unit can also support up to two 150W single-width graphics cards in a two processor, two riser configuration with an additional power feed.


Each Intel Xeon E5-2600 processor socket contains four memory channels that support three DIMMs each for a total of 12 DIMMs per installed processor or a grand total of 24 DIMMs per server. ProLiant DL380p Gen8 supports HP SmartMemory RDIMMs, UDIMMs, and LRDIMMs up to 128GB capacity at 1600MHz or 768GB maximum capacity.


HP FlexibleLOM provides bandwidth options (1G and 10G) and network fabric (Ethernet, FCoE, InfiniBand), with an upgrade path to 20G and 40G when the technology becomes available. HP ProLiant DL380p Gen8 provides a dedicated iLO port and the iLO Management Engine including Intelligent Provisioning, Agentless Management, Active Health System, and embedded Remote Support. This layout allows users to manage the DL380p, without taking over a port from the other four 1GbE offered on-board.

Monitoring and Management

HP Active Health System provides health and configuration logging with HP’s Agentless Management for hardware monitoring and alerts. Automated Energy Optimization analyzes and responds to the ProLiant DL380p Gen8’s array of internal temperature sensors and can signal self-identification location and inventory to HP Insight Control. The HP ProLiant DL380p Gen8 is Energy Star qualified and supports HP's Common Slot power supplies allow for commonality of power supplies across HP solutions. If you configure a ProLiant DL380p Gen8 with HP Platinum Plus common-slot power supplies, the power system can communicate with the company’s Intelligent PDU series to enable redundant supplies to be plugged into redundant power distribution units.


HP also offers three interoperable management solutions for the ProLiant DL380p Gen 8: Insight Control, Matrix Operating Environment, and iLo. HP Insight Control provides infrastructure management to deploy, migrate, monitor, remote control, and optimize infrastructure through a single management console. Versions of Insight Control are available for Linux and Windows central management servers. The HP Matrix Operating Environment (Matrix OE) infrastructure management solution includes automated provisioning, optimization, and recovery management capabilities for HP CloudSystem Matrix, HP’s private cloud and Infrastructure as a Service (IaaS) platform.


HP iLO management processors virtualize system controls for server setup, health monitoring, power and thermal control, and remote administration. HP iLO functions without additional software installation regardless of the servers' state of operation. Basic system board management functions, diagnostics, and essential Lights-Out functionality ships standard across all HP ProLiant Gen8 rack, tower and blade servers. Advanced functionality, such as graphical remote console, multi-user collaboration, and video record/playback can be activated with optional iLO Advanced or iLO Advanced for BladeSystem licenses.


Some of the primary features enabled with advanced iLO functionality include remote console support beyond BIOS access or advanced power monitoring capabilities to see how much power the server is drawing over a given period of time. In our case our system shipped with basic iLO support, which gave us the ability to remotely power on or off the system or provided remote console support (which ended as soon as the OS started to boot). Depending on the installation, many users can probably get by without the advanced features, but when tying the server into large scale-out environments, the advanced iLo featureset can really streamline remote management.

Design and Build

Our DL380p Gen8 review model came with a Sliding-Rack Rail Kit and an ambidextrous Cable Management Arm. The rail kit system offers tool-free installation for racks with square or round mounting holes and features an adjustment range of 24-36 inches and quick release levers. Installation into telco racks requires a third-party option kit. The sliding-rack and cable management arm work together, allowing IT to service the DL380p by sliding it out of the rack without disconnecting any cables from the server. Buyers opting for a more basic approach can still buy the DL380p without rails, or with a basic non-sliding friction mount.


The front of the DL380p features one VGA out and two USB ports. Our unit features eight small form factor (SFF) SAS hot-plug drive bays. There is space for an optional optical drive at to the left of the hot plug bays. With a quick glance of the status LEDs on the front, users can diagnose server failures or make sure everything is running smoothly. If no failures have occurred, the system health LEDs are green. If a failure has occurred, but a redundant feature has enabled the system to continue running, the LED will be amber. If the failure is critical and causes shutdown, the LED illuminates red. If the issue is serviceable without removing the server hood, the External Health LED illuminates. If the hood must be removed, the Internal Health LED illuminates.


The level of detail that HP put into the DL380p is fairly impressive at times, with items as simple as drive trays getting all the bells and whistles. The drive tray includes rotating disk activity LEDs, indicators to tell you when a drive is powered on, and even when not to eject a drive. At times when it seems that all hard drives or SSDs get simple blinking activity LEDs, HP goes the extra mile to provide users with as much information as they can absorb just by looking at the front of the server.


Connectivity is handled from both the front and rear of the DL380p. VGA and USB ports are found on both sides of the server for easy management, although both VGA ports can't be used simultaneously. Additional ports such as a serial interface, and more USB ports can be found on the back of the server along with FlexibleLOM ports (four 1GbE in our configuration) and the iLO LAN connector. To get the ProLiant DL380p Gen8 server up and running immediately, HP ships these servers standard with a 6-foot C-14 to C13 power cord for use with a PDU.


Internally, HP put substantial effort into making the ProLiant DL380p Gen8 easy to service while packing the most features they could into the small 2U form-factor. The first thing buyers will notice is the cabling, or lack thereof, inside the server chassis. Many of the basic features are routed on the motherboard itself, including what tends to be cluttered power cabling. Other tightly-integrated items including the on-board FlexibleLOM 4-port 1GbE NIC and the Smart Array P420i RAID controller, adding network and drive connectivity without taking over any PCIe slots. In a sense this allows buyers to have their cake and eat it too, packing the DL380p with almost every feature and still leaving room for fast PCIe application accelerators or high-speed aftermarket networking interconnects such as 10/40GbE or 56Gb/s InfiniBand.


When it comes time to install new hardware or quickly replace faulty buyers or their IT departments will enjoy the tool-free serviceable sections of the DL380p. No matter if you are swapping out system memory, replacing a processor, or even installing a new PCIe add-on card, you don't need to break out a screwdriver. HP also includes a full hardware diagram on the inside of the system cover, making it easy to identify components when it comes time to replacing them.

Cooling

Inside most server chassis, cooling and cable management can go hand in hand. While you can overcome some issues with brute force cooling, a more graceful approach is to remove intrusive cabling that can disrupt proper airflow for efficient and quiet cooling. HP went to great lengths integrating most cables found in servers, including power cabling, or went with flat cables tucked against one side for data connections. You can see this with the on-board Smart Array P420i RAID controller that connects to the front drive bay with flat mini-SAS cables.


While keeping a server cool is just one task to accomplish inside a server, making sure it works and is easily field-serviceable are two distinct items. All fans on the HP DL380p held in with quick-connects, and can be swapped out by removing the top lid in seconds.

On the cooling side of things, the DL380p does a great job of providing dedicated airflow for all the components inside the server chassis, including add-on PCIe solutions. Through the BIOS, users can change the amount of cooling needed, including overriding all automatic cooling options to force max airflow if the need arises. If that's the case, make sure no loose paperwork is around, as it will surely be sucked to the front bezel from the tornado of airflow. In our testing with PCIe Application Accelerators installed and stressed, stock cooling, or slightly increased cooling was enough to keep everything operating smoothly.

Power Efficiency

HP is making a big push into higher efficiency servers that can be seen across the board with a greater push for lower power-draw components. The ProLiant DL380p includes a high-efficiency power supply, our model is equipped with the 94% efficient Common Slot Platinum PSU.


Less power is wasted as heat in the AC to DC conversion process, which means that for every 100 watts you send your power supply, 94 watts reaches the server, instead of 75 watts or less with older models.

Conclusion

We've logged hands on time with just about every major server brand, and even some not so major brands. The one thing that resonates with the HP Gen8 ProLiants is just how tightly they're put together. The interior layouts are clean, cabling is tucked away (or completely integrated with the motherboard) and thoughtfully done and even the PCIe riser boards support the latest generation PCIe storage cards. From a storage perspective, the latter is certainly key, if an enterprise is going to invest in the latest and greatest storage technology, the server better support the expected throughput.

While this first part of our HP ProLiant DL380p review gives a comprehensive overview of the system itself, part two will incorporate performance and compatibility testing with a wide array of storage products. While most SATA and SAS drives will perform roughly the same in any system, the latest PCIe storage solutions have a way of separating the men from the boys in the server world. Stay tuned for our second review installment that will cover these storage concerns and other key areas such as multi-OS performance variability.

Availability

HP ProLiantDL380p Gen8 Servers start $2,569 and are available now.

Linux Lite Is Heavy on Features and Usability

In a computing world distracted by distro overload, Linux Lite is a lightweight Linux OS that has no trouble handling a heavy workload.


Long gone are the days when it took hours to install and set up Linux on a computer, but most Linux distros still need a bit of configuration to adjust the massive desktop options to your liking.

Not so with Linux Lite. It is one of the few out-of-the-box experiences I have had in testing Linux distros that let me actually be up and working in under five minutes.

That is not to say I haven't spent time installing various preferred packages. That's the great beauty of using Linux. It gives users so much freedom to individualize the look and feel and choice of applications.

To its credit, Linux Lite does not install excessive numbers of programs to clutter up menus and home directories. Instead, it installs a collection of work and play packages to get you working and surfing. Rather than spend time removing or tolerating unwanted programs, users can simply add their preferred tools.

Testing That Testimony

My routine in checking out any unfamiliar Linux distro is to see how quickly the live session boots on my standard equipment. Usually, the first sign of duress is the lack of a wireless connection. The next stumbling block is usually one or more snags while installing the new distro to the test computers.

Linux Lite impressed me from the start. It loaded a live session in under 30 seconds with a prompt to enter my wireless connection credentials. I liked its speedy responsiveness when loading files from the DVD. I liked its fresh look and uncluttered design.

Linux Lite won me over when it installed on even my balkiest test computers without a single sign of trouble. That satisfaction continued as I performed my next critical step. Using nothing more than the installed set of packages, I attempt to use the distro to do actual work tasks for as long into my work day as I can tolerate.

I was pleasantly pleased not to have to make any settings changes or packages additions except one minor matter. Linux Lite defaults to two virtual workspaces. It only took a right click to change that setting to my standard four. The new setting was immediately activated in the workplace switcher app on the dock.

Look and Feel

Linux Lite uses the Xfce desktop environment. Not having any other choices is sometimes a good thing: It removes any quandaries about which optional offering would be better. Of course, if you prefer more memory-intensive flash-bang desktop effects, Xfce may not suit your comfort zone.

Xfce is fast and lightweight, but it is also very simple to use without compromising on performance. The Linux Lite developers did not make the mistake so many others make by embellishing or altering the integration of the desktop environment to make it more distro-unique.

I was able to easily change the default two-tone gray background with a right click on the desktop to select the Desktop Properties menu. Linux Lite offers a nice collection of colorful background images as part of the live session functionality. Often this personalizing option is not available with other Linux distros until you make a hard drive installation.

Working Desktop

The desktop screen is neat and simple, with easy navigation to the menu, system settings and configuration options. As I already mentioned, though, Linux Lite really needs no finessing to be truly usable from the start.

The menu is fairly standard yet simple and intuitive. For example, the folders are organized according to their categories. The slide-out menus are also well-categorized.

You can use the Run Program search box at the top of the menu to run a program rather than scroll through the standard menu -- but that only works if you actually know the name of what you want.

Another option is to use the Application Finder in the Accessory menu. Just select a category in the left column and click on the desired installed application in the right column.

Everything Just Works

Linux Lite has a lot going for it to make a very good first impression. With Linux Lite the basics work out-of-the-box.

For example, the only included browser is Firefox. I would have preferred the Chromium Browser, but Firefox was a reliable browser for me to start my work day rather than take time to install Chromium. Even Firefox's preinstalled state allowed me to play my online music collections and view YouTube videos without having to track down missing players and plug-ins.

When I needed to take that extra step to use some added third-party programs, relief was just a menu item away. The restricted extras package in the main system menu includes proprietary libraries and applications that enable the use of TrueType Fonts, Java, Flash and the ability to playback MP3s.

Strong System Support

Especially useful for configuring Linux Lite your way is the menu item to easily install special packages. The list includes a file and folder search tool and instant messaging. It also lets you add remote desktop, restricted extras, torrent software, video editing, VirtualBox, a weather monitor and/or Wine.

Linux Lite lacks its own community repository. The full range of package installation and software removal is done with the Synaptic Package Manager. A separate application in the main menu lets you install system updates.

The latest version of Linux Lite is "Amethyst," or version 1.0.6, released in June. The distro is based on Ubuntu 12.04 LTS, which includes five years of system updates without worrying about having to upgrade.

If you are not a fan of Ubuntu Linux, do not let the family lineage deter you from trying Linux Lite. Other than the system underpinnings, you will not see any trappings from the Ubuntu desktop.

Bottom Line

Linux Lite is an ideal starter distro for those looking for an upgrade when Windows XP dies early next year. Yet this distro is not just an easy Linux intro for newcomers -- it is a suitable workhorse distro for seasoned Linux users as well.

Even without installing it to a hard drive, you can reliably use Linux Lite in a live session from the DVD or USB drive installation. The USB option does not let you save your settings and software changes, however -- it is not intended for true portable use with persistent memory. However, if you use it only in live session mode, you can save your personal files externally.

Linux Lite is fully featured with the preinstalled software to be usable right out of the box.

Micron P420m Enterprise PCIe SSD Snap Review

The Micron P420m is an enterprise application accelerator that ranges up to 1.4TB in total capacity that leverages the PCIe interface and is uniquely offered in both a half-height, half-length (HHHL) and 2.5" form factors. Micron has opted for 25nm MLC NAND for the P420m to meet not only mainstream market requirements for performance and reliability, but also to provide a more cost-effective and higher capacity offering than their P320h which is paired with SLC NAND. The other core difference between the P420m and the P320h is that Micron has added capacitors to protect in-flight data in the event of an unplanned loss of power. The additional data protection feature keeps the card powered long enough to flush all writes to the NAND, giving enterprises one more layer of data protection. The HHHL card interfaces via PCIe Gen2 x8 to achieve sequential read performance up to 3.3GB/s with writes up to 630MB/s and random reads up to 750,000 IOPS and 95,000 IOPS for write activity. The 2.5" interfaces over PCIe Gen2 x4 for up to 1.8GB/s and 430,000 IOPS, respectively.


At its core, the Micron P420m features the same custom Micron/IDT ASIC controller as its sibling the Micron P320h PCIe and the same RAIN architecture (redundant array of independent NAND). RAIN provides device-integrated algorithms that use RAID5 across flash channels, enabling Micron to deliver greater performance, reliability and data integrity. RAIN also guarantees continuous drive operation even after a channel failure by kicking off an automatic background rebuild when a failure is detected. RAIN is entirely automated and runs entirely in the background without degrading system-level performance.

The application accelerator market at large offers a wide scope of options in terms of capacity and performance, but one feature that can be overlooked is power consumption. Some solutions draw so much power and expel so much energy that in-host cooling is a serious concern. The P420m on the other hand is well within the PCIe spec and is rated at just 8W in standby (7W on the 350GB 2.5"), with active power ranging up to 30W depending on capacity, form factor and performance tuning options. The 2.5" form factor is rated at 14W for 350GB and 22W for 700GB. The HHHL form factor is rated at 22W for 700GB, while the 1.4TB model is quoted at 25W with power throttling turned on and 30W without its activation.

As noted, the Micron P420m is available in both HHHL and 2.5" PCIe form factors. The 2.5" PCIe form factor continues to be unique to Micron, though others have shown demos of the technology. Dell has created a backplane for their 12G PowerEdge servers for the drives that allows them to be mounted in groups of four in traditional front-facing drive bays. Of course being able to access the drives via front of server without having to power down the system and remove the lid to service the drive is seen as a substantial benefit by some. It also helps that Micron's 2.5" PCIe drives are by far the fastest storage available in that drive size, as seen in our 2.5" P320h review.

The 2.5" ships in 350GB and 700GB capacities, while the HHHL is available in the 700GB and upper-echelon 1.4TB capacities. The HHHL cards provide endurance of 5 PBW (700GB) and 10 PBW (1.4TB). Our review units are four 1.4TB capacity cards.

Design and Build

The Micron P420m is a half-height, half-length x8 PCIe application accelerator that features a single controller mounted onto the mainboard, with daughter boards attached to house more MLC NAND and power-fail capacitors. As with its top of the line, SLC NAND-based P320h sibling, the P420m follows the universal HHHL spec, enabling installations for just about any open server PCIe slot.


The power-fail capacitors are new to the Micron P420m to help ensure data integrity in the event that power is lost, as Micron enabled write-back caching leveraging DRAM on the P420m. The P320h had its default configuration set to write-through, although users could (at their own discretion) enable write-back caching for increased performance. Since the default conditions changed to help drive greater performance from the new MLC platform, Micron opted to ensure reliable performance regardless of the conditions of the installed environment.


The top of the card features an adhesive black plate with Micron P420m branding. This plate also serves to protect the top layer daughter board with its power-fail capacitors, as well as the controller's heat sink. That controller is a Micron/IDT ASIC controller that was also found on the Micron P320h. As for NAND, Micron includes 64 of their own Micron 31C12NQ314 25nm MLC NAND packages. That comes out to 2048GB or raw capacity, which is then over-provisioned down to 1.4TB available.

Testing Background and Comparables

The Micron P420m Enterprise PCIe SSD uses a Micron/IDT ASIC controller and Micron MLC NAND with a PCIe 2.0 x8 interface.

Comparables for this review:
  • Fusion-io ioDrive2 (1.2TB, 1 x Xilinx Virtex-6 FPGA controllers, MLC NAND, PCIe 2.0 x4)
  • Huawei Tecal ES3000 (1.2TB, 3 x Proprietary FPGA controllers, MLC NAND, PCIe 2.0 x8)
  • Intel SSD 910 (800GB, 4 x Intel EW29AA31AA1, MLC NAND, PCIe 2.0 x 8)

  • LSI 9207-8i SAS/SATA 6.0Gb/s HBA (For benchmarking SSDs or HDDs)
It's worth noting that the comparables we've selected are largely MLC-based drives, with the exception of the SLC Micron PCIe drive. That said, not all PCIe drives are created equally both in terms of performance targets and price. Specific applications require specific storage needs, thus we've opted to standardize the comps on NAND type rather than number of controllers, etc.

Application Performance Analysis

In the enterprise market there is a huge difference between how products claim to perform on paper and how they perform in a live production environment. We understand the importance of evaluating storage as a component of larger systems, most importantly how responsive storage is when interacting with key enterprise applications. To this end, we've rolled out application tests including our proprietary MarkLogic NoSQL Database Storage Benchmark and MySQL performance via SysBench.

In the MarkLogic NoSQL Database environment, we test single PCIe Application Accelerators with a usable capacity greater than or equal to 700GB. Our NoSQL database requires roughly 650GB of free space to work with, evenly divided between four database nodes. In our testing environment, we use an SCST host and present each SSD in JBOD (while some PCIe SSDs leverage software RAID0), with one device or partition allocated per database node. The test repeats itself over 24 intervals, requiring between 30-36 hours total for the SSDs in this category. Measuring the internal latencies seen by the MarkLogic software, we record both total average latency, as well as interval latency for each SSD. - source

OWC Envoy Pro EX Snap Review

The OWC Envoy Pro EX is a USB 3.0 bus-powered portable storage device that offers capacities up to 480GB and is pre-formatted and primarily designed for Apple systems, though PC users can reformat and use the drive as well. The OWC Envoy Pro is the bare unit, while the EX models add SSD storage using OWC's Aura 6G SSDs. OWC's intent when they engineered the Envoy Pro EX was to create storage for the MacBook family that is ultra-portable, high-performance and protected from potential user-damage. The Envoy Pro EX meets those criteria: it can easily fit in a pocket, it offers SSD memory for superior speed compared to HDD-based portable drives, and in using SSD the device has no moving parts and is safe from physical damage in its anodized aluminum body.


OWC's Envoy Pro EX offers a solution to those users who simply require a high performance option to store files that get accessed on multiple machines or as supplemental storage for those on MacBooks with limited internal storage. Certainly bulk storage options are abound that are based around hard drives, but those of course have slower access speeds, may not travel as well and are much bulkier than the very slim Envoy Pro EX.

OWC pricing for The OWC Envoy Pro (0TB) is $79.99, Envoy Pro EX 240GB is $319.99 and Envoy Pro EX 480GB is $599.99. The Envoy Pro EX comes with a three year warranty that features a 48-hour turnaround time, and to add an even greater sense of security, OWC provides one free year of Tier-1 data recovery in the event of data loss.

OWC Envoy Pro EX Specifications
  • High-performance ASMedia 1053e chipset
  • USB 3.0 interface
  • Features
    • Bus-powered via USB 3.0 port (no AC adapter required)

  • Enclosure Weight (no accessories): 3.8 ounces
  • 3 Year OWC warranty and built in USA
Design and Build

The OWC Envoy Pro EX has an extremely rigid construction that feels strong enough to hold up to substantial physical impact. The design mimics that of the Apple MacBook family making it a perfect pair. The top of the ultra-portable Envoy Pro EX is all silver as is the rest of the body. The front features an LED indicator showing light blue when the device has power, and the back of the Envoy Pro EX houses the USB 3.0 port. Flipping over the Envoy Pro EX, the bottom has the product labeling and the rubber feet that grip the drive to a surface. OWC also includes a nice carrying pouch for when the Envoy Pro EX is in transit. Overall the design is quite elegant and is one of the best looking portable storage drives we've had come through the lab.


It's worth noting that users won't be able to use the OWC Envoy Pro EX with USB 2.0; only USB 3.0. The OWC Envoy Pro EX doesn't support USB 2.0, nor does OWC recommend using it. This may be due to a lack of ability for the USB 2.0 port to power the Envoy Pro EX.

Performance

We utilized our Consumer Testing Platform to measure transfer speeds from the OWC Envoy Pro EX 240GB using its USB 3.0 interface. We started with 2MB sequential read and write testing in which the Envoy Pro EX came in at 244.76MB/s and 239.56MB/s respectively, while random large-block transfers measured 240.67MB/s read and 239.63MB/s write. These figures essentially top off at the limitation of USB 3.0 - not a reflection on the Aura 6G SSD's native capabilities.


To compare the OWC Envoy Pro EX 240GB to other flash-based portable solutions on the market, we've also tested the Iomega SSD Flash External 128GB as well as the LaCie P'9223 Slim SSD 120GB using their USB 3.0 interface. We began with the Iomega by looking at 2MB sequential read and write testing. There, the Iomega SSD 128GB posted 204.62MB/s for reads and 120.49MB/s for writes. In our random large-block transfers, it measured 201.92MB/s read and 107.09MB/s write. These numbers show that the OWC Envoy Pro EX provided far better write rates and more throughput for read activity as well, but the Iomega marks are reasonable given that it has been out for a couple of years now.

We then moved on to the LaCie. For 2MB sequential read and write testing, the LaCie P'9223 Slim SSD 120GB came in at 285.50MB/s and 188.70MB/s, respectively. For random large-block transfers, the LaCie 120GB SSD had marks of 273.65MB/s for read activity and 189.14MB/s for write activity. The LaCie SSD performed with the most throughput for read activity of the 3 drives coming in just above the OWC Envoy Pro EX 240GB SSD, while the OWC 240GB produced the greatest write activity transfer rates.


Overall the OWC product performed very well, with nearly identical small and large block performance over both reads and writes. The complete picture is very respectable, offering steady performance in every case near the top scores possible from the USB 3.0 interface.

Conclusion

The OWC Envoy Pro EX is a USB 3.0 portable drive that utilizes an SSD to deliver high-end performance in a very small footprint. Our test model has a capacity of 240GB though users can opt for 480GB as well. This capacity is delivered by OWC's own Aura 6G SSDs which are backed by OWC's 3 year warranty that includes 48-hour turn around and 1 year of data recovery. The drive is also smaller than many popular smart phones currently available on the market, and it features an extremely durable aluminum enclosure that happens to look great too.

There are only things to like when it comes to the design of the OWC Envoy Pro EX. The enclosure has some super strength, and it looks just like an Apple product that matches superbly to MacBooks. In fact, if it had a white USB 3.0 cable and lost its OWC sticker, you might even confuse it with an Apple design. On top of that, the size really enables users to take the Envoy Pro EX with them anywhere: from travel bags to purses to pockets, it's slim enough to fit. When it came to test performance, the OWC Envoy Pro EX 240GB provided solid throughput around 240MB/s for both read and write activity in 2MB sequential and random large-block testing which was definitely impressive, though top-end speeds are somewhat limited by its USB 3.0 interface. Even so, it's the best overall performance portable storage device we've tested to date.

Pros
  • Premium design
  • Rigid enclosure
  • Extremely portable
Cons
  • USB 3.0 limits the Envoy from greater throughput
Bottom Line

The OWC Envoy Pro EX is a fantastic choice for users that require ultra-portability and performance coupled with a superb design when looking for expanded capacity on the go.

AOpen MP915-B MiniPC Snap Review


The AOpen miniPC, which was first revealed at Computex exhibition in Taipei in June, is set to hit US stores. The machine looks surprisingly a lot like a Mac mini. Both machines measure 165 millimeters square. The AOpen miniPC measures 50 millimeters high, just 1 millimeter shorter than the Mac mini. Both have the same rounded design and a CD slot at the top in the front.


The primary design difference? The miniPC has a power button in the front. Whoops, how could you have possibly called this a look alike!? I personally commend the originality and creativity behind the AOpen design team :)


The miniPC will run Intel’s Pentium-M processor and feature a DVD burner, built in ether, 802.11 a/b/g Wi-Fi, Bluetooth, USB ports, IEEE1394 (Firewire) port, DVI, and S-video connectors. One version will ship with 512MB of memory and a 80GB hard drive. In short, it’s a PC Mac Mini.


The mini computers will be available in the US this month for $399 running Linux or $499 running Windows XP.

If it has a decent video card it might just become my home theater PC.
AOpen launched the XC mini MP45-BDR, a latest addition of the mini PC product family featured the Intel® GM45+ICH9M (Montevina) chipset and the new generation Blu-ray disc reader/DVD writer (Blu-ray Combo drive). It supports new Intel® Core™ 2 Duo (Penryn) processor and provides external frequency up to 800/1066MHz, thus maximizing the performance of the Intel® Core™ 2 Duo. It s also supports up to 4GB dual channel SO-DIMM DDR-II 667/800MHz. Its built-in GMAX4500MHD graphics engine offers full support for Microsoft® DirectX™ 10 to meet image quality and performance requirements for 3D games. In addition, a total of six USB 2.0 ports eliminates the scalability limitation of min PCs and ensures greater flexibility and space.

“Available in limited quantity only, the XC mini featured the high-end Blu-ray disc reader/DVD writer (Blu-ray Combo drive) aims to meet the world needs in high-quality video playback,” said Tony Yang, AOpen’s senior marketing Director. “It proves that its high performance has earned the trust of consumers and it becomes the hub of the digital home entertainment.“ He adds, “in addition to Blu-ray disc playback functions, the XC mini MP45-BDR also delivers DVD±R, DVD±RW, DVD-RAM and CD-R capabilities for data backup and video burning. Eliminating the installation and configuration processes, the preinstalled Blu-ray Combo drive enhances user convenience and is shipped with exclusive Blu-ray video playback edition of Cyberlink PowerDVD software. It offers one-stop shopping for all consumer needs in both hardware and software, demonstrating AOpen’s considerate services to the consumers.”

With even more compact design and only 1.36L in volume, the XC mini MP45-BDR includes six USB 2.0 ports and provides faster transmission as well as hot-pluggable e-SATA ports for easy connection to more devices. The XC mini MP45-BDR can also function as a digital home audio/video center. It support HDCP Full HD 1080P playback with 5.1 channel surround sound output, the new generation Blu-ray disc playback functions, and built-in GMA X4500MHD graphics engine. Through bundled DVI or HDMI port, it can connect to traditional computer monitor, LCD monitor or HDTV, providing high-definition, surround-sound experience.

Other than advanced audio and video playback capabilities, the XC mini MP45-BDR is positioned as a versatile flagship model. It comes with many optional dedicated accessories to meet the needs of a variety of applications. These accessories include: TV tuner for viewing traditional TV and digital TV, 802.11b/g wireless network modules for constructing wireless network at home, and Bluetooth technology for exchanging information with mobile phones and PDA. All these accessories demonstrate that AOpen is not only a leading supplier of mini PC, but also a leading brand creating user experience in mini PC. The XC mini MP45-BDR also fulfills the concept of environmental protection. In addition to set an example in carrying out power and space saving, it actually complies with EU RoHS directive (Restriction of the use of certain Hazardous Substances in electrical and electronic equipment), delivering safe, worry-free operations.

Ubuntu on $199 Acer's C7 Chromebook


Maybe you think the price of Acer's new $199 C7 Chromebook is appealing and that the hardware doesn't look bad, but you're a little worried about using Chrome OS to get your work done. Or maybe you're looking for a small, cheap laptop to run Ubuntu, and you're not really interested in buying a computer running a Windows license you'll never use. If either of those sentences describe you and you aren't afraid of the command line, it's actually pretty easy to convert the cheapest Chromebook yet into a nice little Linux laptop.

Because Chromebooks use a special BIOS and bootloader that is distinct from the ones used in standard Windows laptops, you can't use them to boot just any operating system. This is where ChrUbuntu comes in—it's a version of Ubuntu 12.04 LTS modified to work with Chrome OS hardware. Once it's installed you should be able to use the C7 to do just about everything you could do with a standard laptop running Ubuntu, and the Chrome OS partition is left on the disk so you can still boot into it and use it if you're so inclined.

These instructions should technically work with any Chromebook, but of all the ones on sale today, the C7 is perhaps best-suited to run alternate operating systems. It comes with a roomy (if slow) hard drive out of the box, and can easily be upgraded with more RAM and an SSD to speed it up. The recent Samsung Chromebooks, by comparison, take a less upgrade-friendly approach.

Preparing the Chromebook

Our first step toward getting ChrUbuntu on the C7 is to put it in developer mode. This is a multi-step process: first, turn your Chromebook off, and then press the power button while holding the Refresh (F3) and Esc keys simultaneously. This will boot the Chromebook into Recovery mode (which you'll also need to use to reload Chrome OS if you replace the hard drive—Google's instructions for creating Chrome OS recovery media are here).

If you booted into Recovery mode properly, you should see a screen telling you to insert recovery media. Instead, you'll want to press Crtl+D to toggle developer mode. This will prompt a reboot and a wait of several minutes while your Chromebook is reset. This will also erase any data on your drive, so proceed with caution if you've got anything you want to keep stored on the Chromebook itself.

After entering developer mode, your Chromebook will boot to a scary screen telling you that OS verification has been disabled. You can either wait until this screen disappears, at which point the laptop will boot into Chrome OS, or you can press Ctrl+D again to bypass it. After loading in developer mode, connect to a wired or wireless network, but don't log in—you still have to install the developer mode BIOS before you can install an alternate OS.

At the login screen, press Ctrl+Alt and the Forward (F2) button to bring up the Developer Console command prompt. At the "localhost login" prompt, enter chronos and press Enter. Type sudo bash and press enter, and then chromeos-firmwareupdate --mode=todev. If you see a message telling you that you can press Ctrl+U to run your own self-signed OS kernels, you're ready to install ChrUbuntu!

Installing ChrUbuntu

Type exit to take a step back to the chronos user command prompt. Now, we'll need to download and install the ChrUbuntu files. As of this writing, you'll need to type wget http://goo.gl/i817v; sudo bash i817v and press enter to initiate the setup process, but you may want to check the ChrUbuntu blog to make sure a newer version hasn't been released.


The installer will check to make sure you're running a developer BIOS and show you a message about using an unofficial Chromium OS kernel to enable 64-bit functionality. You won't need to worry about any of this, so just press Enter to continue.

You'll now need to decide what size to make your Ubuntu partition, which will depend on whether you've replaced the built-in hard drive with an SSD. I'm still using the stock 320GB hard drive, so the maximum size recommended by the installer was 292GB; I entered 290GB just to give Chrome OS a little extra breathing room.

Press Enter and the system will partition your disk, reboot, and begin running through Chrome OS's first-time setup process again. You'll have to repeat a few of the steps from above—connect to a network, and press Crtl+Alt+F2 again without logging in. Type chronos to login, and then wget http://goo.gl/i817v; sudo bash i817v to start the ChrUbuntu installer again. Now that you've partitioned your disk, the OS files will begin downloading—the complete size of the download is about 1GB, so it will take some time.

Once the install is completed, the computer will reboot into a fully functional Ubuntu install with a default username and password that are both set to "user." These should probably be changed or deleted.

If you reboot your Chromebook, by default it will continue to boot into Chrome OS, which lives on in its own dedicated partition. If you'd like ChrUbuntu to be the default, open up the Terminal in ChrUbuntu (or the Developer Console command prompt in Chrome OS) and enter sudo cgpt add -i 6 -P 5 -S 1 /dev/sda to change the default boot partition. Changing it back to Chrome OS is as easy as disabling developer mode when you boot the Chromebook, or entering sudo cgpt add -i 6 -P 0 -S 1 /dev/sda at the terminal.

How does it do?

Once you've got Ubuntu running on the C7, it works just as a standard laptop running Ubuntu would. You can install and run anything from the Ubuntu Software Center or other sources and you have full access to the filesystem, making the C7 a much more versatile computer than it is with just Chrome OS installed.

Happily, all of the major hardware—Wi-Fi, Bluetooth, audio, the webcam, and the GPU—appears to be working normally, and the Chromebook's function keys also perform as they do in Chrome OS. This means that games and video content should play normally, and the laptop goes into and out of sleep mode without a hitch.

The trackpad is a bit problematic, however: tap-to-click works fine but two-finger scrolling doesn't. You'll also probably run into some edge cases where things don't work perfectly. Video out over HDMI works, for example, and Ubuntu has multi-monitor and extended desktop support, but audio over HDMI doesn't appear to work as intended. Battery life also continues to be a weak point for the C7—in our testing it gets a little under four hours in Chrome OS, and while we didn't have time to perform extensive scientific testing under Ubuntu, the numbers should be similar or perhaps slightly worse.

The ChrUbuntu blog put out a call for C7 testers a few weeks ago—if you're using ChrUbuntu on the C7 and are experiencing problems, that's the place to report them.

Whither Windows?

We noted in the original review that the C7 Chromebook was just a lightly modified version of one of Acer's Windows laptops, the Aspire One 756. Using some BIOS files intended for that model, I spent some time trying to replace the Chromebook BIOS with the standard one to allow for booting of Windows and other operating systems not supported by the Chromebooks' boot loader.

Unfortunately, such an operation is more complicated than it seems. Standard Acer laptops have a "crisis boot" mode that allows for emergency re-flashing of the BIOS, but that doesn't work on a Chromebook. The Linux flashrom utility used in Chrome OS doesn't support flashing the BIOS ROMs you can download from Acer's support site.

Finally, even if you could find a BIOS file compatible with flashrom, the C7's BIOS appears to be hardware-locked, which is standard for Chromebooks. The original Cr-48 Chromebook prototype had BIOS protection that could be bypassed by applying some electrical tape to the motherboard, but the C7 doesn't have any such quick fix that I could find. It's probable that more enterprising minds will be able to figure out how to convert the C7 into a cheap run-anything laptop, but in the hours I spent trying to unlock the laptop I was unable to do so easily. If you'd like to run Windows apps on the C7, the most feasible solution is probably going to be a virtualization program like VirtualBox, which installs and runs without issue on the C7 once Ubuntu is up and running. - source
