I have a 1.9TB LUN presented from an IBM SVC to several ESX/ESXi clusters which include versions 3.5(ESX), 4.1(ESXi) and 5.0(ESXi). I read that 3.5 has a 32 Host to LUN "recommended" limit.
I'm looking for more detail about this number. Does this apply only to the number of 3.5 hosts that can see the datastore or all ESX hosts combined. And why is it recommended vs a hard limit? We're trying to set up one LUN mapped to as many ESX clusters/hosts as we can in order to support a mass migration to a new environment.
I'm pretty new to the VMWare world so please excuse me if I'm not clear about what I'm asking or have not included other pertinent information.
