IBM Refreshes Broad Swath of Flash Offerings

Yesterday IBM unveiled a sweeping update of its existing flash storage products. These updates cover a range of products, including IBM Storwize All Flash arrays: V7000F, V7000 Gen2+, and V5030F, the FlashSystem V9000, the IBM SAN Volume Controller (SVC), and IBM’s Spectrum Virtualize Software.

The company referred to this effort as a part of a: “Drumbeat of flash storage announcements.” IBM has a stated goal of providing its clients with: “The right flash for the right performance at the right price.”

IBM’s representatives explained that the updates were made possible by the fact that the prices of flash components have been dropping at a rapid pace while reliability is on the rise. The SSD Guy couldn’t agree more.

Here’s what IBM announced:

Starting from the low end and moving up, the V5030F entry-level/midrange array is an Continue reading “IBM Refreshes Broad Swath of Flash Offerings”

Who’s #1 in Flash Arrays?

A recent conversation with some fellow analysts revealed a puzzling set of claims. EMC, at its EMC World conference (May 3-7) claimed to be the leader in flash array shipments. The very next week, in the same Las Vegas hotel, IBM also claimed leadership in flash.

Who do you believe?

Well a friend of The SSD Guy, marketing consultant Jay Kramer of Network Storage Advisors Inc., tallied up all of the leadership claims he could find and provided this list:

EMC is counting XtremIO Arrays as units shipped and according to Gartner Group held the #1 market share position with a 31.1% share, which is over a ten percentage point share lead
IBM is counting capacity of PBs shipped with all of their flash storage solutions: The FlashSystem 840, 900, V840, V9000, DS8000, plus the XIV systems, Storwize V7000, IBM Flash DAS, and IBM PCIe Adapters
NetApp is the leader if you count total flash systems shipped (NetApp-branded plus privately-branded systems) spanning multiple years as their SANtricity operating system and E-Series platforms have sold over 750,000 units
Pure Storage uses its 700% growth to show that it’s the #1 fastest-growing flash storage company
Then, if you want to compare any vendor’s total all flash array (AFA) systems sold this past year against hybrid storage arrays, Nimble Storage beats any of the AFA vendors.

IBM Makes Flash Even Faster

At IBM’s Edge 2013 conference last week the company not only extolled the values of flash, as does anyone who has had a flash experience, but it also showed how flash could be made even faster than it already is.

You’re probably already thinking: “Flash is about 1,000 times as fast as HDD – how do you make it even faster?”

The answer is actually pretty simple: compress the data. If there is a limit to how much bandwidth you have going into and out of a piece of storage, you can speed it up if you can reduce the size of the data that consumes that bandwidth.

Of course, that’s not always easy. Compression often slows data access down, even for HDDs, and it could Continue reading “IBM Makes Flash Even Faster”
