Viewing System Capacity
To view a single system's capacity information, access the Systems screen and then click
the Capacity tab.
Raw capacity for the selected InServ Storage Server is displayed for Total, Fibre Channel,
Near Line, and Solid State capacities. Each of these top level capacity items can be
further expanded to the following:
Note: In the normal situation, the capacity displays show you the space that
is consumed by provisioning (e.g. CPGs, Volumes, and underlying LDs) and
the space that is reserved by the system for spares.
When chunklets or PDs fail, the data that was on those chunklets is moved
onto the spares. The total amount of space consumed by provisioning does not
change, nor does the total amount of spares in the system. However, there is
an overlap in the numbers because the used spares are counted in the total
number of spares (total spares = unused + used spares) AND in the
provisioning (because parts of the LDs/CPGs/Volumes) are now using those
spares. In this case, an asterisk (*) appears to indicate that the numbers will
not add up due to this shared space.
