HP XP Performance Advisor Software - Manual (Page 316)

Based on the above selection, the Performance Estimator displays the estimated values in the
following non-editable text boxes:
•
Raw Capacity - Indicates the cumulative disk space that is available (for both data storage
and parity operations) for the selected configuration.
•
R1/R5/R6 Usable (GB) - Indicates the disk space that is available as data storage for
the selected configuration. The value shown is applicable only for the R1 and R5 RAID
types.
•
Total Usable (GB) - Indicates the total disk space that is available as data storage for the
selected configuration. The value is same as that displayed for the R1/R5 Usable (GB).
IMPORTANT:
•
The disk type and the disk size that you select are independent of each other.
•
Each workload has a predefined maximum intensity level and depends on the disk type, RAID
type, and the RAID groups that you select.
•
Read the above–mentioned workloads in the following manner as explained for the 8K Random
Mix (60/40 r/w) workload:
8K Random Mix (60/40 r/w):
◦ 8K – I/Os comprising of 8,000 random reads and writes.
◦ Random Mix – I/Os is a random (not sequential) mix of both read and write operations.
◦ (60/40) – 60% of the I/Os are reads and 40% of the I/Os are writes.
