Viridity's EnergyCenter Brings Energy Management To The Data Center
March 31, 2010 11:16 AM
Posted by David Hill
Mark Twain famously said, "Everyone talks about the weather, but nobody does anything about it." Conversely, in IT everyone talks about data center energy efficiency, and many vendors are trying to do something about it. The introduction of Viridity's new EnergyCenter offers a particularly intriguing example. Viridity, a start-up company, tackles the data center energy-efficiency problem head on with EnergyCenter, a software approach to enabling data center energy optimization. Now corporate initiatives to go "green" are well and good, but there a couple of pragmatic business reasons why energy efficiency is being increasingly scrutinized within IT organizations.

FalconStor And Violin Add SSD To NSS

While I had been waiting for FalconStor to add flash support to their Network Storage Server (NSS) storage virtualization software, I was expecting flash volumes off a Fusion-IO or TMS PCIe flash card with promises of automated tiering to arrive sometime before Snow White's prince. I was pleasantly surprised when the folks at FalconStor called to tell me they were aiming a little higher than that and using Violin's solid state memory array as a cache.

Global CIO's Bob Evans and I were talking with Rod Adkins, the senior vice president who runs IBM's Systems and Technology Group. That operation is Big Blue's Big Kahuna, accounting for $19 billion in annual revenues and including IBM's chip, server, storage and systems software businesses. Did I mention that Adkins is also responsible for IBM's global manufacturing, procurement and customer fulfillment operations? All of this is by way of saying that, when Adkins speaks, one should listen.

Tight Squeeze: EMC Joins The High Density Storage Brigade
January 19, 2010 08:48 PM
Posted by Howard Marks
Back in the Twentieth century the increase in disk drive bit density allowed us to keep up with growing data sets by periodically replacing disk arrays with ones using drives that hold 4-8 times the data in the same space. Lately the data we have to store has been growing faster than disk drive capacity, and as a result, vendors have been experimenting with high density arrays packing more drives in the same space. This week EMC threw their hat in the ring with a double-deep rack for Clariion mid-range arrays.

I confess I can't get much excited about either green or smart grid technology, but that doesn't mean that both aren't legitimate new beachheads in which -- to update Scott McNealy's famous aphorism -- the networking stuff will be the big deal. The whole deal, in fact.
