Figure 44 Warning when items in the management group are reaching optimum limits
1. Volumes and snapshots are nearing the optimum limit. One cluster is nearing the optimum limit for storage systems.
Configuration errors
When any item exceeds a recommended maximum, it turns red, and remains red until the number
is reduced. See
Figure 45 (page 108)

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.
