Use the guidelines in this section to design the shared storage solution for a cluster:
For maximum flexibility, we recommend that you create only one cluster resource per LUN.
A LUN cannot be concurrently accessed by servers belonging to different clusters. This means that all resources on a given LUN can be active only in a given cluster at any given time.
We recommend that you use only one LUN per pool, and only one volume per pool. If you use multiple LUNs for a given shared NSS pool, all LUNs must fail over together.
It is possible to create multiple pools per LUN or to use multiple LUNs per pool, but these alternatives not recommended.
