New Study Forecasts Huge Enterprise SSD Growth

Enterprise SSD Revenues will Cycle with NAND Flash PricesObjective Analysis has published a new study, Enterprise SSDs: Technologies & Markets.

This study breaks the market into 23 application types, and provides an explanation of each along with forecasts by major application category.

Virtualized systems will drive the greatest 5-year average unit shipment growth, at 85%, although the data center will retain its leadership in enterprise SSD consumption.  Overall enterprise SSD unit shipments will grow at an annual average of 32% through 2018.

Since SSD prices are cost-based, with roughly 80% of the cost coming from flash chips, NAND flash price swings will cause Continue reading

White Paper: Matching Flash to the Processor

Moving flash into the memory channel to get fast parallel performance I have just added a new white paper onto the Objective Analysis website: Matching Flash to the Processor – Why Multithreading Needs Parallelized Flash.

This document examines the evolution of today’s CPUs, whose clock frequencies have stopped increasing, but now exploit parallelism to scale performance.  Multiple DRAM channels have also been added to performance computing to add parallelism to the memory channel.

Storage hasn’t kept pace with this move to parallelism and that is limiting today’s systems.

New NAND flash DIMMs recently introduced by Diablo, SanDisk, and IBM, provide a reasonable approach to adding parallel flash to a system on the its fastest bus – the memory channel.  This white paper shows that storage can be scaled to match the processor’s growing performance by adding flash DIMMs to each of the many DRAM buses in a performance server.

The white paper is downloadable for free from the Objective Analysis home page.  Have a look.

IBM Launches Flash DIMMs

IBM's eXFlash DIMMOn Thursday IBM announced its X6 product family, the sixth generation of the company’s successful EXA server architecture.  A smaller byline of the introduction was the company’s new eXFlash memory-channel storage or eXFlash DIMM which is offered as one of many flash options available to X6 users.

Close followers of The SSD Guy already know that I am a serious advocate of putting flash onto the memory bus.  Why slow the technology down by Continue reading

OCZ: Bankruptcy Certain, Outcome in Question

OCZ Corporate HeadquartersOn Wednesday OCZ announced that its bank accounts had been seized by one of its creditors and that the company would file for bankruptcy, but it did not commit on which of two courses of action it would take:

  • To file for bankruptcy and sell itself as an ongoing business to Toshiba
  • To file for bankruptcy and liquidate

If the company is sold to Toshiba the bankruptcy court will require an auction to be held to assure that the price that Toshiba pays is the best price that the company can get.  This means that there is still the possibility of another company actually acquiring OCZ.  Although Seagate was rumored to be interested there are certainly others who are also preparing bids.

OCZ has good technology and a loyal retail customer base, but one year ago Continue reading

LSI SandForce SSD Controllers Move the Knee in the Curve

LSI SandForce SF3700 Controller DuraWrite ImprovementsLSI’s SandForce has just rolled out its SF3700 family of four SSD controllers aimed at the Entry Client, Mainstream Client, Value Enterprise, and Enterprise Storage marketplaces. Performance is impressive, with worst-case random PCIe IOPS at 150K read/81K write and 94K/46K for the SATA interface.

The SF3700 family builds on the division’s first two product families by adding a choice of PCIe or SATA interfaces, LDPC error correction, and a boosted set of flash management features.  The SSD Guy will explore this last point after highlighting the other two.

By providing both PCIe and SATA interfaces LSI is directly addressing the future: PCs are aiming to move to the m.2 SSD specification rather than Continue reading

Kaminario Seizes SPC1 Title Again

Storage Performance Council LogoFor the second year in a row little Kaminario has beat the large established storage array vendors to produce the highest SPC1 benchmark rating at 1.24 million SPC-1 IOPS.

The results of the Storage Performance Council’s SPC-1 report, show Kaminario surpassing last year’s record performance by 20k IOPS.

Interestingly enough Kaminario set the 2012 record using DRAM while this year the company was able to do it with its fourth-generation all-flash K2.

Why is the SPC1 test so highly respected in Continue reading

Violin & Microsoft Take a New Approach to Scaling

Violin all-flash arrays with embedded Microft softwareViolin Memory and Microsoft have jointly announced a novel way of harnessing the power of Windows Server software.  Violin will be shipping its memory arrays with a special version of Windows Server 2012 R2 pre-installed on the embedded server that manages the internal operations of Violin’s all-flash array.

Violin explains that native support of specially-optimized versions of Windows Server and System Center that have been tuned for an all-memory array will provide improved performance and economics for large-scale enterprise cloud deployments.

The system can internally run Continue reading

Solving SSD Power Spike Issues

The following guest post was contributed by Doug Dumitru the CTO of Easy Computing Company (EasyCo), a software R&D company which develops and markets SSD performance enhancement solutions

Doug Dumitru, EasyCoIt would appear that you could build an all-SSD array by simply replacing all of the HDDs in a cabinet with SSDs.  I tried that and ran into some surprising issues that were very confusing at first.

SSD spec sheets, might lead you to believe that power is just not an issue.  For example, Samsung lists the power use for a 512GB 830 SSD at 0.127W (typical) for “Active Power Use”.  This implies very low demands on the system power supply.

If you do some more research, you find that the peak power usage is a lot higher.  AnandTech, in a review article reports sequential write power draw at 5.14W and random write power draw at 5.8W. In that 2.5” SSDs use the 5V power rail exclusively, this is more than Continue reading

SanDisk Turns 25

SanDisk Market Open 27Aug13Today SanDisk announced that the company is now 25 years old and celebrated the fact by ringing the NASDAQ opening bell.

It’s intriguing to The SSD Guy that the company has reached 25 years, and has reached annual revenues of about $6 billion dollars, yet one of the founders is still the CEO.  Sanjay Mehrotra has been leading the company since the retirement of co-founder Eli Harari, and has Continue reading

IBM Adds Server-Side Caching

IBM's FlashCache Server-Side Caching SoftwareIBM today announced its FlashCache Storage Accelerator, a software product that supports flash caching in a broad range of systems.  FlashCache operates over three families of IBM servers (System x, BladeCenter and Flex System) and a variety of flash types to accelerate any back-end storage, including non-IBM storage arrays.

Although the cache’s data is dynamically updated to match the random workloads of virtualized systems (i.e. to accelerate VMware), it also improves the performance of Windows and Linux environments.

The cache uses a Write Through policy to solve a number of Continue reading
