I/O load generators for HP-UX?

[Mott Given]

Does HP-UX have any publicly available free tools that can be used as an I/O load generator for benchmarking disk arrays? I am looking for a tool like iometer, which is apparently not available for HP-UX?

If no tools are publicly available, then are there any HP internal tools that I could get an HP person to run for us?

IOzone is a nice tool for doing exactly this. One particularly nice feature is that you can get it to output in excel format for easily knocking up graphs.

Is there a compiled version of iozone available for HP-UX?

Mott,
Google "HP Diskbench". It's available on the HP DSPP site.

A simple dd will also do that
Read performance check

timex dd if=/dir/20GB_file of=/dev/null bs=32k

Write thing.

timex dd if=/dev/zero of=/dir/20gig_file bs=32k count=xxxxx

Make sure you have enough space.

I will second the suggestion to use iozone. I don't know if precompiled binaries are distributed, but suspect that it will compile just fine under HP-UX. The author of iozone is actually an HP engineer.

After I got diskbench, the doc files said "DB (Diskbench)is a disk subsystem performance tool. DB can measure properties like IOs/sec and MB/sec for different disk subsystems. This feature is not supported on MP systems."

So it looks like I would not be able to use it running from our MP servers? Does anyone have any experience that disproves that?

Mott,
Below is the link to the DSPP Diskbench page. I see whant you mean. The first sentence says MP is not supported, and the description later says 1 way or MP. We have used it on many MP machines, and have had no problem.......it reports I/O fine. I think what HP means is it doesn't support reporting processor utilization with MP machines, but you really want the I/O numbers, and it will give you them.........
