Replacing the Virtualisation Component – II

Thanks to Chuck who pointed out to me SVC’s ability to move virtual WWNs between nodes during replacement. At some stage in the future I may get to play with SVC but I haven’t so far, so this feature eluded me. Question: is SVC the *only* block virtualisation appliance to offer this functionality and is it a seamless operation or ... Read More »

IBM’s Storage Announcements

Using Virtualisation for DR

It’s good to see virtualisation and the various products being discussed again at length. Here’s an idea I had some time ago for implementing remote replication by using virtualisation. I’d be interested to know whether it is possible (so far no-one from HDS can answer the question on whether USP/UVM can do this, but read on). The virtualisation products make ... Read More »
