XIV Clustered Disk Arrays Get More Oomph And Capacity
July 26, 2011 Timothy Prickett Morgan
IBM has kicked out the third generation of its XIV clustered disk arrays, high-end machines for delivering lots of bandwidth and high-end software features such as thin provisioning, snapshotting, asynchronous and synchronous mirroring, and hot upgrades of cluster components.
Big Blue bought disk array upstart XIV back in January 2008 so it would have a clustered disk array that was more expandable and more resilient than the monolithic DS8000 series of high-end disk arrays, which are based on Power Systems servers. The XIV machines are based on Intel Xeon processors running Linux, with main memory serving as cache for disks.
