We currently use IBM V5000 arrays for our Commvault backup target to land our deduped backups. We are starting to review other options to see what other fast, cost effective options are out there. I do prefer to use Fiber Channel connections, but open to options. Since Commvault is really the brain in our scenario, the storage array does not really need any features, just good speed.
What Vendor Storage arrays do you use? Are you happy with it?
