For benchmarking SCSI, I use the following tools:
hdparm -t -T /dev/sda # evaluate sequential buffer-cache (memory)
# and disk speed
Bonnie (with a file size >> memory)
# evaluate filesystem I/O, OS latency, and drive seek times
benchio
# evaluate PCI memory bandwidth, and sequential best-case disk
# throughput. benchio bypasses the buffer-cache and filesystem
# completely by sending commands directly to the SCSI subsystem.
# There is no other use than verifying the manufacturer's
# figures.
Now, if you are talking about fileservers, you are mainly interested
in the Bonnie result, possibly also a few file-creation and file-deletion
benchmarks, and of course network speed itself, ie all those operations
executed through network.
An idea would also to run the final application on the clients and
compare on the same hardware. For me, the most ``real life''
benchmark is your final application.
