One-to-One LUNs for VMWare Virtual Machines, or Multiple VMs per LUN?

MI am in process of rolling out a CS-215, to be as dedicated storage for a VMWare ESXi 5.5U2 environment.


My question is about whether or not to share out an individual LUN for each dedicated VM, or to share out a LUN large enough to host multiple VMs.   My thinking behind the 1-1 LUN/VM concept is that it will allow me to snapshot the VM LUNs individually, so that I can recover individual VMs using the Nimble snapshot manager quickly, versus having to export a snapshot to the filesystem and then copy the VM's files back to the LUN directory.   It just seems cleaner to be able to roll back the snapshot using the SANs native functions, than the VMWare snapshotting functions.


Currently we're only going to be hosting about 10-15 VMs, each of them being relatively static (Windows machines hosting single purposes applications, and not SQL Server or Exchange).
