hardware issues in the environment, no failed jobs in the last 24 hours and
that the data protection is working without any issues.
If there are any alerts, you can drill down to the relevant alert page to
investigate the cause. Storage Advisor provides alerts for capacity utilization,
hardware, data protection, and jobs status.
Analyzing data in the information gauge
The information gauge provides a visual indication of the total capacity of all
storage systems managed by Storage Advisor.
The capacity indicated in the center of the ring is the total usable capacity
available via the configured parity groups. After you add a storage system
and configure parity groups, the total capacity indicator will show the
capacity from the newly added storage system. The Thin Used capacity (light
green ring) indicates the total capacity that is currently being used. If the
usage is around 70-80% of the total capacity, you may receive capacity alerts
based on the thresholds set by your storage administrator. The default
thresholds are 70% and 80%, and can be changed during pool creation.
The light grey ring that provides a sum of capacities of all pools in the
systems should be closer to 100% capacity. This would mean that you are
using your entire parity group capacity by allocating it to pools. If the Thin
Used capacity ring (light green) nears the total capacity (light grey ring) then
you may run out of pool capacity soon. In such a case, expand the pool to
consume more capacity.
If you notice that the total pool capacity (light grey ring) and Thin used (light
green ring) values are getting closer to total capacity, you may be running
out of disk capacity on one or more storage systems and would need to add
disk space to increase storage capacity. Before adding disk space:
• Review the information gauge for each storage system to identify which
storage system needs additional capacity.
• Review unused disks for each storage system to determine if any raw
unused capacity is available for parity group creation.
Capacity subscription beyond the total available capacity should not be an
issue if your thin capacity utilization is well within the total capacity.
