VA/Nike Performance Utility

The problem I am having is with a VA-7400 array. As background I have a software vendor that is updating their software. As it stands, all their old data is on a Nike array and all their new data is on the VA-7400. The vendor is complaining about performance issues on the VA-7400 as compared to the Nike array. When I ask what they are using to justify their claim they waltz around the question. My question is there a utility that I can run to compare throughput on the Nike verses the VA-7400? I am running 11.0 on a K-580.

Hi

Postmark is a tool to mesure filesystem performance, you can get it from:

Another good performance test is to run a backup to a fast device (or to /dev/null).

You can use a tool such as GPM (Glance Plus?) which can report disk utilisation.

Let me check my docs as I may have something more.

Re: VA/Nike Performance Utility

Anyone experiencing performance problems with the VA should upgrade the firmware to HP17 and the latest Command View management software. Then, enable the new pre-fetch algorithm. This combination can have dramatic results for highly utilized systems, or low concurrency sequential workloads.

Try it, let me know what happens

One could use Iozone to get performance data. This is my favorite I/O tool.
