Using a 3PAR StoreServ 7200 for datastores shared by a couple of vSphere ESXi Hosts running a small number of VM's on each host.
From a performance point of view, is it better to have multiple datastores, with each VM on its own datastore rather than putting all the VM's on a single datastore?
I'm thinking that maybe separate datastores are similar to separate hard drives and you want to divide I/O between seperate datastores to speed things up. Does this make sense? Or does it not work that way with datastores on a SAN?
