Dear StorageMojo: migrating from Centera to Isilon
A reader asks: Do you have any tool to move External Files (nearly 70 TB) from Celerra & Centera to Isilon faster? The StorageMojo take I know EMC made it difficult to leave their Centera system for competitive systems, but making it difficult to leave for another EMC...
SSDs in arrays: the Pure Storage view
Pure's Matt Kixmoeller saw the Are SSD-based arrays a bad idea post and, unsurprisingly, responded. The SSD is Key to Economic Flash Arrays is a good post and I urge interested readers to check it out. Pure has a stellar team with deep experience. Their views are...

Are SSD-based arrays a bad idea?
Think: if NAND flash storage arrays were being developed today, what is the chance that we'd put the flash into little bricks and then plug a bunch of them into a backplane? So why do it now? It is a truism of design that when a new technology is developed, we use it...
NAND’s dimming future
Another StorageMojo Best paper, The Bleak Future of NAND Flash Memory, presented at this year's FAST '12 conference, quantifies flash's declining reliability, endurance, and performance as density increases. Researchers Laura M. Grupp and Steven Swanson from the UCSD...
Virtualizing storage controllers
A hardware storage controller is an expensive guarantee that you're using old technology to handle your most important data. Hardware specs are frozen early in the typical 18-24 month development cycle so by the time you get your "new" controller it is already 2 years...
Doubling flash write performance through retention relaxation
FAST - File and Storage Technology - is a must-see conference for StorageMojo, and I'll be reviewing several Best Papers from FAST '12 . While most emerging technology is developed in private company labs, FAST is where much of the first publicly available research is...
SSDs and the TPC-C top 10
If SSDs are so great, shouldn't we see the results in TPC-C benchmarks? They are, and we do. But there are some surprises. Cost Looking at the TPC-C top 10 performance results showed the dramatic impact SSDs have had on the cost per thousand transactions (tpmC). There...
Gridstore snags Geoff Barrall
BlueArc and Drobo founder Geoff Barrall has a new perch: Gridstore, one of the companies I've been following for almost 3 years. Geoff is the new executive chairman. Formal announcement is expected this week. Gridstore's concept is a low-cost scale-out NAS appliance...
Learning from customers
EMC's Chuck Hollis blogged about The Vendor Beating a couple of months ago. The unspoken question in the post is "how do we understand what customers are telling us?" He writes As an employee of a large IT vendor, I've been at the receiving end of a reasonable number...
