Re: Disk I/O benchmarks and monitoring

iozone is really easy to build ... have you tried? I don't have any 5.3 systems, but if you need it, I can compile it on 64-bit 5.2 and make it available to you.

Hello,

What tools do you use to monitor and graph disk I/O throughput?

iozone looks good but there doesn't seem to be a build for AIX 5.3 at the
64 bit level.

I need to run some tests on a new FastT that we're getting. We expect to
put a database on it that performs a fair amount of random reads but mostly
sequential writes. We're comparing RAID5 to RAID10 performance to see if
the price difference is worth any additional performance we'd see in RAID
10. It will be behind a 2-node SVC with plenty of cache so I'm interested
to see how well the RAID5 stacks up to the RAID10.

Thanks,

Drew
