12 Using Performance Estimator for XP and
P9000 disk arrays
This chapter discusses the performance estimation for XP and P9000 disk arrays.
Introduction
P9000 Performance Advisor enables you to determine the optimal performance of your XP (XP24000,
XP12000) and P9000 (P9500) Disk Arrays after configuration collection is complete for these XP disk
arrays. It provides a framework called the Performance Estimator for estimating their performance.
Performance Estimator focuses on the RAID groups, instead of the LDEVs or the LUNs. Based on the
RAID group configuration and the workload that you select, the Performance Estimator helps you to
estimate the disk capacity and array performance data, such as the I/O per second, MB/second,
LDEV response time. The estimation is based on the RAID groups and predefined workloads that you
can select for the disk array. The subsystem configuration parameters can be rapidly entered and the
results are accurate to within 20%.
CAUTION:
The numbers displayed are only an estimate. The results shown are based on readings taken in a
controlled environment. HP cannot guarantee the results in your data center.
IMPORTANT:
The Performance Estimator does not support XP20000, XP10000, XP1024/128, XP48, and SVS200
disk arrays.
