HP StorageWorks Enterprise Virtual Array Online Firmware Upgrade Best Practices (5697-6388, January 2007)

Light load te

sting

Performed mu

ltiple online code loads under a light load. The objective was to observe application

resiliency t

otheﬁrmware upgrade. The expected outcome was that the ﬁrmware upgrade should

complete wi

thout the applications failing or having excessive latency.

The test ste

ps included the following:

1. Start load simulators on all three applications.

2. Start capturing metrics with Windows Performance Monitor.

3. Allow I/O to run for at least one hour.

4. Perform ﬁ

rmware upgrade.

5. Save captured metrics.

6. Repeat steps 1-5 two more times.

Heavy load testing

Performed multiple online code loads under a heavy load. The objective was to observe application

resiliency to the ﬁrmware upgrade. The expected outcome was that the ﬁrmware upgrade should

complete without the applications failing or h aving excessive latency.

The test steps included the following:

1. Start load simulators on all three applications.

2. Start capturing metrics with Per fmon.

3. Allow I/O to run for at least one hour.

4. Perform ﬁrmware upgrade.

5. Save captured metrics.

6. Repeat steps 1-5 two more times.
