Maintaining a Storage Array

Performance Tuning

Over time, as a storage array exchanges data between the hosts and physical

disks, its performance can degrade. Monitor the performance of a storage

array and make adjustments to the storage array operational settings to

improve performance.

Monitoring Performance

Monitor the performance of a storage array by using the

save storageArray

performanceStats

command. This command saves performance information

to a file that you can review to determine how well the storage array is

running. Table 6-1 lists the performance information saved to the file.

Table 6-1. Storage Array Performance Information

Type of Information

Description

Devices

Devices are:

• RAID Controller Modules — The RAID controller module

in slot 0 or 1 and a list of the virtual disks owned by the

RAID controller module

• Virtual Disk — A list of the virtual disk names
• Storage Array Totals — A list of the totals for both RAID

controller modules in an active-active RAID controller

module pair, regardless if one, both, or neither are selected

for monitoring

Total I/Os

Number of total I/Os performed since the storage array was

started

Read Percentage

Percentage of total I/Os that are read operations (calculate

the write percentage by subtracting the read percentage from

100 percent)

Cache Hit Percentage Percentage of reads that are fulfilled by data from the cache

rather than requiring an actual read from a physical disk

Current KB/second

Current transfer rate in kilobytes per second (current means

the number of kilobytes per second since the last time the

polling interval elapsed, causing an update to occur)

Maximum KB/second Highest data transfer value achieved in the current

kilobyte-per-second statistic block
