I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

If you are just interested in the spped at which data can be sent or recieved to a specific LUN you could just use standard commands like dd to create a block based file on the lun.... just make sure to specifcy the block size and the block count you want.

fiber channel adapters look just like scsi controllers to an operating system so they can be tested with the same tools... but also just like scsi controllers, most will be limited by the disks on the other end before they reach their theoretical max speed (assuming you dont have an AFA or something super fast on the far end)

Let mek now if that helps!

I used bonnie++ before for disk performance stats but these things really only work if using comparisons or to get a trend over a time period.

Red Hat is not providing any tool for measuring HBA utilization, so you could check individual vendors may provide such tools for their HBAs. However for Disk Testing and Benchmarking: IOzone and Bonnie++
