11.0 HP StoreVirtual Storage User Guide (AX696-96275, December 2013)

Configuration guidance
The optimal and recommended number of storage items in a management group depend largely
on the network environment, the configuration of the SAN, the applications accessing the volumes,
and how you are using snapshots. However, the Configuration Summary can provide some broad
guidelines that help you manage the SAN to obtain the best and safest performance and scalability
for your circumstances. These guidelines are in line with HP tested limits for common SAN
configurations and uses. Exceeding these guidelines does not necessarily cause problems. However,
your performance may not be optimal, or in some failover and recovery situations, may cause
issues with volume availability.

Best Practice summary overview
The Best Practice summary provides a reference about best practices that can increase the reliability
and/or performance of your SAN configurations. The Best Practice summary is available when
you create a management group, and is located on the Summary tab with the Configuration
Summary. If you have more than one management group on the SAN, each group is listed in the
summary.
NOTE: You can also view all the best practices in the Best Practice Summary pane on the SAN
Status Page.
