The Evolution of Hitachi Data Systems

sunnyday_business_alliance_128

It wasn’t long ago that many people used to think of Hitachi Data Systems, aka HDS as nothing more than a box shifter.  I myself have to admit at being complicit in that view, being somewhat negative of the release of Hitachi High Availability Manager in 2009.  The other criticism levelled at the company was the quality of their software, ...

Gartner ECB (External Controller-Based Disk) – 4Q2012

Gartner EBC - All Vendors

The latest Gartner ECB survey is out and as discussed in my last post, I’ve updated my data to reflect the latest set of figures.  The vendors all have ups and downs each quarter so this data is particularly interesting as it covers year end 2012 and allows four years of comparisons from 2009 through to 2012.

Hitachi Attacks Migration Costs with Non-Disruptive Migration Feature

Hitachi Non-Disruptive Migration

It’s probably fair to say that data migration is one of the most tedious tasks in storage management.  Moving data from one array to another, simply to decommission a piece of hardware or for load and capacity balancing, doesn’t ever inspire me. But it’s a necessary evil and one I’ve done many times.  Unless the existing storage configuration has been ... Read More »
