warning by turning that line red. As soon as the total number of iSCSI sessions reduces below the
boundary, the summary bar returns to the previous indicator, either orange or green.
Storage systems in the management group
The optimum number of storage systems in a management group ranges up to 20. If the management
group contains 21 to 30 storage systems, the Configuration Summary appears orange for that line
of the management group. Exceeding 30 storage systems triggers a warning by turning that line red.
As soon as the total number of storage systems reduces below the boundary, the summary bar returns
to the previous indicator, either orange or green.
Storage systems in the cluster
The optimum number of storage systems in a cluster ranges up to 10. If the cluster contains 11 to 16
storage systems, the Configuration Summary appears orange for that line of the management group.
Exceeding 16 storage systems in a cluster triggers a warning by turning that line red. As soon as the
total number of storage systems reduces below the boundary, the summary bar returns to the previous
indicator, either orange or green.

Reading the configuration summary

Each management group in the SAN is listed on the Configuration Summary. Underneath each
management group is a list of the storage items tracked, such as storage systems, volumes, or iSCSI
sessions. As items are added to the management group, the Summary graph fills in and the count is
displayed in the graph. The Summary graph fills in proportionally to the optimum number for that item
in a management group, as described in the
Optimal configurations
Optimal configurations are indicated in green. For example, in
storage systems in the management group "CJS1." Those 15 storage systems are divided among the
clusters "c" "c2" and "c3." The length of the graph is relative to the recommended maximums in each
category. For example, 3 storage systems in cluster c3 are closer to the cluster recommended maximum
for storage systems than the 43 iSCSI sessions are to the maximum recommended iSCSI sessions for
a management group.
