HP XP P9000 Performance Advisor Software - Manual (Page 314)

•
Disk type –15K RPM
•
RAID type and RAID groups –144 RAID groups for RAID 1 (2D+2D)
•
Workload – 8K Random Writes
•
Intensity – 4096 threads/sec
HP XP P9000 Performance Advisor estimates:
•
576 disks (Number of Disks) are required
•
I/Os on the disk set would be 46442/sec
•
MB/s that the array can receive per second would be 380 MB
•
Time taken for the array to respond (R.T (ms) for the read—write requests would be 91 R.T
(ms)
Following is an example on estimating raw and usable capacities of an XP24000 Disk Array:
Your inputs: RAID type and RAID groups –144 RAID groups for RAID 1 (2D+2D)
HP XP P9000 Performance Advisor estimates:
•
Raw disk capacity would be 84096 GB
•
Disk space available for data storage (R1/R5/R6 Usable (GB)) would be 39744 GB
The available disk space shown is only for R1/R5 RAID types.
•
Total or the usable storage capacity will be 39744 GB
Based on the above estimate, you can implement this configuration or modify the inputs to receive
a different configuration.
Estimating performance for XP12000 Disk Arrays
To estimate the performance for an XP12000 Disk Array:
1. Click Reports+Performance Estimator in the left pane.
The Performance Estimator screen appears.
2. Select the XP disk array model from the Array Type list. This list displays the XP disk array
models only for the monitored XP disk arrays.
The Performance Estimator screen corresponding to the selected XP disk array appears.
The Array List displays the XP disk arrays that belong to the selected XP disk array model. By
default, the Performance Estimator screen displays the current configuration for the first XP
disk array that appears in the Array List.
IMPORTANT: Performance Estimator supports:
•
72 GB, 146 GB, 300 GB, and 400 GB disks.
•
RAID 1 (2D + 2D) and RAID 5 (7D + 1P) configurations.
•
SAS and SSD drive types.
3. Continue estimating the performance for the default selected XP disk array or select a different
XP disk array from the Array List.
4. To estimate the I/Os, MB/sec, R.T. (ms), and number of disks required:
a.
Select the disk type from the Disk Type 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
