Measuring/benchmarking I/O performance - what tools?

Hi all,

I am looking for some tools that would allow me to stress test and measure
the maximum performance on a V880 and a 4500. I would like to do a raw
disk performance measurement and how much performance I lose when I let
veritas volume manager manage the disks. I am looking for a tool like
hdparm from the linux side.

I know I can use dd and iostat or whatever but I would like to get
something that would do the testing over a specified amount of time and
gives me a summary.

Thanks
