We have just purchased a Lefthand/HP4330 san, comprised of 6 nodes, with 3 nodes each placed in 2 separate buildings, configured in a stretched metro cluster, so network raid will distribute the data
across both sites, to all of the nodes. Usable capacity is 18TB. We are thinking of creating two luns to satisfy the storage heartbeat requirement; one small lun for iso's and the 2nd
storage heartbeat of approximately 300GB in size, and the remaining balance of the space, approximately 17+TB, as one large lun for all of the virtual machines.
The hosts are esxi/vsphere 5.1
Does anyone see any drawbacks to this plan?
