Performance testing disks in HP-UX?

[boje]

Hi!

I was wondering if there is any good benchmarking or performance software for testing disks in HP-UX? I need to compare a disk on our EVA SAN to a disk on our Netapp NAS.

I normaly use perfview and glance, but it's not disk specific, but for me more than enough.

You can try with dd to read data and compare the times.

time dd if=/dev/dsk/... of=/dev/null bs=... count=...

Yes, for comparing purpose DD command is better idea.

Thanks

And for monitoring purpose sar, glance and HP perfview are good options.

Thank you! I will try using DD to compare two disks.

u can use

suxus004 # sar -d 5 10

HP-UX suxus004 B.11.23 U ia64 09/30/08

04:47:16 device %busy avque r+w/s blks/s avwait avserv

here monitor %busy

glance is another option

perfview

dd if=/dev/rdsk/cxtxd0 of=/dev/null bs=1024


RETURN VALUE
Exit values are:

0 Successful completion.
>0 Error condition occurred.

DIAGNOSTICS
Upon completion, dd reports the number of input and output records:

f+p records in Number of full and partial blocks read.
f+p records out Number of full and partial blocks

Patrik,

I have to point out that all dd is going to test is relative sequential read/write IO performance - it won't tell you anything about any other sort of IO.

Better would be to get a tool like iozone:

http://www.iozone.org

Even better would be to actually compare your applications on both arrays.

Be aware that the nature of WAFL on NetApp is such that performance can degrade over time, so make sure you run your tests for at leats 24 hours.

Hello,

Our friends already gave you couple of good
references. There are many more.

For example:

For HP-UX 11.23 or newer (11.31), HP offers
it as long as you sign an ETD Test Tool Non
Disclosure Agreement.

Please contact your representative.

HP-UX Meatgrinder is a port of ETD's
Linux Meatgrinder test to the HP-UX
operating system.

It is available for Itanium and PA-RISC.

Here are some of the test threads:

Ancillary
Audio
Cache
CPU
File System
Flash
Floppy
Interupt
Memory
MultiPCU
Network
PCI Master
Raw Disk
Tape
and more.

If you look for older messages in the forum,
you will find more tools.

Cheers,

VK2COT

Where can i download HP-UX Meatgrinder?

Patrik,

You can't download meatgrinder.

As indicated its an internal HP tool which requires certain agreements to be signed with HP before it can be provided. You would have to request it from your HP contacts. I have to say I'm not sure it would be provided anyway, as typically its used by other vendors as part of qualification and certification testing, rather than by customers for performace tests. In my opinion you'd be better to stick with the tools already discussed.
