Enter the PCIe SSD. Moving flash to the PCIe bus provides better performance scaling, but many initial revisions of PCIe SSDs leveraged existing standards, such as AHCI, for host communication. This leads to performance degradation and excessive CPU overhead as performance scales. As explained in our Defining NVMe article, NVMe is a new storage protocol designed specifically for non-volatile memory. A slew of architectural refinements combine to provide the best performance possible over the PCIe interface. Intel's DC P3700 (covered in-depth in our Intel DC P3700 1.6TB NVMe Enterprise Review) is one of the fastest PCIe SSDs available, and the combination of NVMe and consistent performance provide enhanced scalability when deploying multiple units.

LiOn deployed in Facebook datacenters for power backup

Paul Alcorn | Fri, Nov 14 2014 11:08 AM CST

Power consumption is the highest ongoing expense in the datacenter, and for giants like Facebook it can easily add up to billions of dollars per year. One of the most obvious sources of power consumption spawns from cooling costs. Power consumption generates heat, and Facebook has grabbed the low-hanging fruit by moving to open-air datacenter designs that radically reduce cooling requirements. Now Facebook has turned their attention to UPS systems for the next layer of power savings. Reducing overall power consumption is key because it also incurs the expense of power backup. During a power loss event the systems automatically fall back to massive UPS systems that provide enough power, typically 90 seconds worth, to cover the gap until backup generators come online. Facebook has already altered UPS design by migrating from large central UPS systems to seven-foot tall server cabinets interspersed throughout the datacenter.

Today these massive power backup systems rely upon lead-acid batteries, but now Facebook is experimenting with the same type of lithium-ion batteries found in today's latest electric vehicles. The long term cost of maintenance is lower for lithium-ion batteries, and they also deliver more power in a smaller footprint. Facebook is experimenting with designs that embed lithium-on batteries at the rack level. Two batteries will slide into each rack and provide UPS protection. This design also reduces the chance of UPS failure. If a standard centralized UPS fails the entire datacenter can go down. With rack-level battery backups, only small groups of servers would be effected by individual failures.

Recent advances in lithium-ion battery technology have been fueled by electric car development. Vehicles like the Volt, Tesla, and Leaf, have ushered in advanced battery technology and also lowered the overall cost. Now that cost of Li-on batteries has fallen they have become a sensible alternative for UPS applications in massive datacenters. Facebook is integrating their new designs into their Open Compute initiative, which might serve to expand the widespread use of Lithium-ion in the datacenter. There is no word on how increased demand would affect the overall pricing.

New development tool from A*STAR speeds 20TB HDD HAMR development

Paul Alcorn | Thu, Nov 13 2014 10:05 AM CST

Lately HDDs aren't gaining in capacity as quickly due to the limitations of PMR (Perpendicular Magnetic Recording). PMR stores magnetic bits of data vertically, allowing manufacturers to cram more data onto the HDD's platters, which provides more density than the previous horizontal method. Every new technology has its limits, and PMR has nearly reached the end of its evolutionary cycle. Now manufacturers are turning to HAMR (Heat-Assisted Magnetic Recording) to increase density. HAMR uses a small laser to heat the surface of the platter to 800 degrees Fahrenheit before data is written. The laser is incredibly small and embedded into the drive's write head, and the small heated surface area cools back down in under a nanosecond.

New development tool from A*STAR speeds 20TB HDD HAMR development | TweakTown.com

Heat alters the magnetic properties of the disk for this nanosecond in time, and removes or reduces the superparamagnetic effect while data is written. This process allows for exponential gains in density, and HAMR drives with up to 20TB of storage are on the horizon. While this technology sounds a bit far-fetched, working development drives have already been displayed. With any new technology one of the immediate concerns is a lack of development tools. A team from A*STAR, led by Hongzhi Yang and the National University of Singapore, have designed a pump-probe laser to test HAMR devices. This allows accurate testing of temperature-dependent recording in localized regions without actually destroying the media. This is one more step on the path to creating affordable HAMR HDDs, and the first Seagate HAMR HDDs are projected to release in 2016 timeframe.
