HP Surestore NAS 8000 SAN Solution Integration Manual

Network and Storage Planning 9
The HP NAS 8000 SAN system also supports multiple LUNs and volume groups. This
configuration is more flexible for future upgrades and allows upgrades to an HA cluster
without having to lose the storage configuration or any data.
For maximum flexibility in the use of storage space, do not create large numbers of volume
groups. You can divide volume groups into separate file volumes to segregate storage for
separate users, departments or purposes. There is no need to create a large number of LUNs or
volume groups for creating user partitions.
