• R.T. (ms) - Indicates the time taken in milliseconds for the XP disk array to respond for the se-
lected configuration.
• Number of disks - Indicates the total number of disks that are available per the estimate for
the selected configuration.
5.
To estimate the raw capacity, R1/R5/R6 usable (GB), and the total usable (GB) capacities:
a.
Select the disk size from the Disk Size in GB list.
b.
Select the RAID type from the RAID Type list.
c.
To choose the number of RAID groups to be configured for the selected RAID type, click the
triangular button on the # RGs horizontal scroll bar and holding it down, drag the button
either forward or backward on the horizontal scroll bar. You can configure a maximum of
288 RAID groups for RAID 1 (2D+2D) and 144 RAID groups for RAID 5 (7D+1P).
Accordingly, the text box on the right side of the # RGs horizontal scroll bar displays the
selected number of RAID groups. The RAID groups number increases or decreases depending
on where you place the triangular button on the horizontal scroll bar. You can also enter a
different RAID group number, increase, or decrease the level using the triangular buttons
that appear next to the text box.
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 se-
lected 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) workload:
8K Random Mix (60/40):
• 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.
