Talking to VM:Secure or DirMaint is orders of magnitude faster than talking to "the SAN people". Where N-port ID Virtualization comes into play, the human game gets even slower: we have to have per-guest virtual WWPN(s) before we make the storage request. Please understand: I am not knocking NPIV. I am only pointing out to those new to SAN that it is more like they are used to and may also be easier to manage if the storage is pooled into something VM controls. -- R;
