The use of virtual server storage is growing, with 93% of the firms in the most recent Storage magazine Snapshot survey having virtualized at least some of their servers.
A whopping 93% of companies have virtualized at least some of their servers, and most have had to make corresponding adjustments to their storage environments. With an average of 68% of their servers virtualized, IT managers still rely primarily on block storage to support the load: Fibre Channel SAN is the main virtual machine (VM) storage resource (56%), while 43% use iSCSI SANs; 38% use NAS and 16% use multiprotocol arrays. Sixty-four percent have at least one array dedicated to supporting VMs, and 69% have specifically purchased a new storage system for their VMs. And it's a good thing they have those new arrays, as 57% are using more capacity with VMs than they did before virtualization. How hard/easy is it to manage all this stuff? It's a pretty even split: 37% say it's a little/lot harder than before, 28% claim it's about the same and 34% find it a little or a lot easier.
