New Report Posts Results of IT Manager IOPS Survey

From Report: "How Many IOPS Do You Really Need?"Tom Coughlin and I have just released a new report that helps shed a lot of light on a pretty challenging subject: We asked nearly 200 IT managers to tell us how much storage performance their systems require.  They provided candid replies about their IOPS, latency, and capacity needs for a number of leading applications.

The results of this survey are compiled in a 80-page report titled How Many IOPS do you Really Need?  This one-of-a-kind report provides responses for all of Continue reading

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

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

White Paper: Using Flash as Memory

DRAM, Flash, and HDD HierarchyToday NAND flash is being shoehorned into HDD formats simply because it is persistent – the data doesn’t disappear when the lights go out.  This approach fails to take advantage of NAND’s greatest strength – its low cost relative to DRAM – and this prevents it from fully meeting the needs of most data centers.

Since 2004 NAND has been cheaper than DRAM, and today its price per gigabyte is an order of magnitude lower than that of DRAM.  NAND is cheaper and slower than DRAM, and HDD is cheaper and slower than NAND.

A role better suited to NAND flash technology is Continue reading

Webinar: Flash Best Practices

I had the opportunity to participate in a round table webinar covering the best practices for solid state storage on July 18.  The hour-long session (including Q&A) can be replayed at BrightTalk.

In this round table webinar entitled Best Practices for Solid State Storage Implementation storage analyst Tom Coughlin moderated three of us, Radoslav Danilak of Skyera, Esther Spanjer of SMART Storage Solutions, and The SSD Guy (Yours Truly) in a Continue reading

SanDisk to Acquire SMART Storage

The following is excerpted from an Objective Analysis Alert e-mailed to our clients on 2 July, 2013:

SanDisk to Acquire SMART Storage SystemsSanDisk Corporation announced on 2 July 2013 an agreement to acquire SMART Storage Systems, the SSD arm of SMART Modular Technologies, for $307 million in cash and equity. The transaction is expected to close in August, 2013.

SMART has strong SSD technology that allows the company to ship MLC-based SSDs with endurance specifications superior to those of some SLC SSDs.  The SSD maker had shipments of about $25M in its most recent quarter.

The SMART acquisition will be the fourth Continue reading
