HP Systems Insight Manager 7.2 Technical Reference Guide

• Total Size
The storage volume's total size.
• RAID Level
The RAID level of the storage volume. Typically, this value is supplied by the array's SMI-S
provider. If the SMI-S provider does not supply a value, HP SIM calculates the RAID level
based on the values for Package Redundancy and Data Redundancy as follows:
RAID levelData redundancyPackage redundancy
RAID 010
RAID 511
RAID 121
RAID 612
RAID 15/5122
If the RAID value is calculated by HP SIM, an asterisk is added to the RAID value (for example
RAID 5*).
Capacity Information

The Capacity Information table lists available capacity metrics for storage arrays in the Metric
column and the corresponding disk space value in the Size column. For each metric, the disk space
value is expressed as a percentage of the array's total capacity. The metrics in the Capacity
Information table also appear as percentages in a pie chart below the table. If a value in the table
shows an Undetermined value, the pie chart does not appear.
HP SIM discovers external LUs (a feature of External Storage XP) on XP arrays that are managed
by Command View XP Advanced Edition. When an XP array has external LUs, the Total Capacity
