•
Bare metal LUN sizes vary, depending on the application requirements.
•
When creating a LUN, ensure that LUNs are distributed evenly across the SPs. Even LUN IDs
are owned by SP A, and odd LUN IDs are owned by SP B.
•
You can change a VP pool LUN allocation owner only by deleting the LUN. Make sure you
properly assign SP ownership and distribute the LUNs evenly across the SPs before adding data
to the LUNs.
•
When using thin LUNs for VMware, ensure that the VMware Datastore is not created as thin.
•
The sum capacity of all thin and thick LUNs (not the thin pools) and all RAID groups should not
exceed the maximum capacity of the array.
