test eva performance

Any one knows how can i test the performance of my EVA. I have one disk presented to one server, I wanna copy some data on it, I wanna know how many MB can i copy on my EVA drive.

Well, it depends on _what_ you want to test. For Windows, I suggest that you pick up the "IOMETER" program.

But be warned - the "performance" (I/Os per sec or MB per sec) heavily depends on the IO pattern that you define. Play a bit with it; choose between random and sequential IO, increase the IO size or the number of outstanding IOs... and you will see what I mean - you can pretty much create a result that you want ;-)

My experience with the EVA arrays has been that to achieve anything close to their best when running many simultaneous job streams. Total throughput just keeps going up up up.

arf...

Sorry, I meant that you need many parallel jobs to achieve top throughput, in case that was less than clear:-)
