Editor:- May 28, 2016 - For 9 years the Top SSD Companies has been one of the most popular articles here on the mouse site. You may ask - is it still needed? -The answer is yes. Read the new Q1 2016 edition to see who's still in the running for your attention when it comes to thinking about multi-role adapted, intensive-memory data architectures (SSD).

IBM and leadership in enterprise flash market share

In May 2015 - IBM announced it had been the number #1 all-flash storage array vendor in 2014, having shipped more petabytes and units for Solid-State Arrays than any other competitor - citing an industry market report from Gartner.

IBM said that in 2014 it had sold more than 2,100 FlashSystems, totaling 62 petabytes of capacity.

"With over a third of the world's 2014 all-flash array capacity on IBM FlashSystem, this solution is proving itself as the all-flash enterprise storage solution of choice across Tier 1 enterprise and cloud deployments around the world," said Michael Kuhn, VP and Business Line Executive, IBM Enterprise Storage.

Editor's comments:- many vendors claimed they were #1 in flash arrays at about the same time. And this inspired a blog - Who's #1 in Flash Arrays? - by Jim Handy - founder Objective Analysis - which discussed a "puzzling set of claims" by various competing rackmount SSD companies - who all claim to be #1 in the flash array market.

Who's who in SSD? - IBM

by Zsolt Kerekes, editor - April 28, 2014

IBM was ranked #2 in the Q1 2014 edition of the Top SSD Companies published here on - having moved up 9 places from the previous quarter. (This IBM's highest rank to date - in the 7 years of publishing this series.)

That was a strong affirmation that the SSD market is interested in what it sees IBM doing in the enterprise.

That interest was weighted more towards IBM's rackmount storage systems than in its server side SSD solutions at the time of measuring this - although of course - that could change.

Editor's comments:- re IBM and SSDs - September 2012

It took many years for IBM's SSD strategy to materialize into a recognizable shape.

Like other server companies - initially it was not in IBM's interests to educate customers about SSDs because they feared it would reduce server sales. But as I predicted in my 2003 SSD market adoption article - as soon as user knowledge about SSDs reached a critical mass and other server makers started to adopt them - server makers like IBM potentially realized they would lose server sales if they didn't support them.

Before their born-again enthusiasm for SSDs - IBM (in 2006) had publicly ridiculed products from SSD makers such as Texas Memory Systems - and / or claimed that other SSD products in the market weren't good enough to use yet. (A similar ploy to another SSD latecomer Seagate.)

Like many other server companies IBM initially went for the "safe" option of remarketing, reselling or rebadging proven SSD products from companies like Fusion-io, STEC, SanDisk and others.

IBM's recently announced agreement to acquire Texas Memory Systems (August 2012) has within it the potential to rapidly scale into a multi-billion dollar revenue SSD business unit.

July 2007 - SanDisk announced that its SATA 5000 2.5-inch SSD will be offered as an option in IBM's new BladeCenter HS21 XM.

April 2008 - IBM Previews Racetrack Solid State Storage

August 2008 - Fusion-io's SSDs were the secret ingredient in an IBM "million IOPS" story.

September 2008 - IBM announced a technology collaboration with Fusion-io

In February 2009 - IBM published a well written article - SSDs for Enterprise Storage (pdf) which introduces the need for SSD acceleration and explains IBM's strategy in this market.

In May 2009 - STEC confirmed that its SSDs are oemed in several popular IBM servers and storage systems.

In December 2009 - Fusion-io announced that its ioMemory PCIe SSD technology has been adapted by IBM who will remarket these solutions (initially with upto 320GB capacity) as its High IOPS SSD PCIe Adapters for use in System x servers.

In August 2012 - IBM announced it will acquire Texas Memory Systems

In January 2014 - IBM disclosed it had shipped over 1,500 fast rackmount SSDs in its FlashSystem 800 range - based on the RamSan product line acquired from Texas Memory Systems. IBM also launched a new range of servers which were the first in the market to include - as standard - memory channel SSDs (low latency DDR3 DIMM flash SSDs) supplied by SanDisk and based on the design created by SMART and Diablo.

Don't worry about the endurance of our FlashSystems
Editor:- October 7, 2014 - Worried about endurance?

"None of the thousands of FlashSystem products (fast rackmount SSDs) which IBM has shipped has ever worn out yet! - says Erik Eyberg, Flash Strategy & Business Development at IBM - in his new blog - Flash storage reliability: Aligning technology and marketing. "And our metrics suggest that will remain true in almost all cases for many, many years (certainly well beyond any normal and expected data center life cycle)"
What got me thinking about the need to write this blog was thinking back to a bunch of conversations I had on the subject of those many small flash array vendors whose marketing communications energies seem to be inappropriately overinvested in theme songs and musicals which compare their star products with those of EMC.
"compared to EMC"
In most markets these vendor knowledge gaps would be fed back up the marketing intelligence chain by a direct sales force.

IBM aims to be multi-billion dollar flash systems supplier
Editor:- April 12, 2013 - 3 years ago I wrote a blog about the confusing nature of the "RamSan" brand of SSDs from Texas Memory Systems given that all the recent models in the family were in fact flash memory rather than RAM based - and furthermore some of the models didn't connect via an FC SAN but used PCIe instead.

So it wasn't a surprise to see in yesterday's announcement by IBM (who acquired TMS last year) that the RamSan designation has been dropped in favor of the more accurate sounding "FlashSystem" in those models which migrated intact to IBM's enterprise flash product line.

So - for example in the category of high availability rackmount SSDs - the old RamSan-720 (SLC) and RamSan-820 (MLC) have become the new IBM FlashSystem 720 and 820.

If you're not already familiar with these fast HA SSDs - the thinking behind their design came out in an interview I has with Holly Frost, CEO of TMS when they were launched in December 2011.

Unless I missed them - then it doesn't look to me as though TMS's PCIe SSD models have been so fortunate. I couldn't see them in IBM's range of PCIe SSDs (High IOPS Modular Adapters) which are based on products and technologies from Fusion-io and LSI.

That no-show may be due to the fact that - unlike TMS's rackmount systems which were software agnostic - a lot more work is required to efficiently integrate server based SSDs into a wide range of server products. But I anticipate that TMS's big architecture SSD controller technology will resurface in future IBM SSD cards.

Much more significant was the news that IBM is investing $1 billion in research and development to design, create and integrate new flash solutions into its portfolio of servers, storage systems and middleware. IBM also announced plans to open 12 centers of flash competency around the globe. That demonstrates confidence in the future scale of the SSD market and its perspective related to computer history.
