Best practice, or least administration, to setup SAN for hosting VMs (non bootfroSAN). How many Luns, etc.?
Posted on 2008-10-03
I'm firing up a PROD farm using an LSI array with Brocade FC fabric. VMware, both their engineers and documentation, evade from answering what is a typical setup for supporting 4 hosts (vMotion) and approximately 100 VMs. I don't want to hold anyone's feet to the fire, I just need to know what is typical and the easiest to support. My last position, I supported two SAN environments with three hosts each (no vMotion) and they dedicated a single LUN at 220% (iSCSI Netapps) per VM for snapshots. If VMware has a 128-LUN limitiation, this could pose an issue in fairly short order.
Is 4 LUNs OK? 8? How would I (you) label them and categorize them?
