So, I have a series of questions into ServerFault about LeftHand SAN's (Questions 1441 and 4478). One of the responses I received questioned the throughput of the iSCSI data returning from the SAN being restricted to the 1GB network card.
I think it is a very good point to look at.
Now to see if this would be an actual bottleneck for my purpose I should perform some benchmarks on the current production server.
What utilities should I use for profiling?
If there are special metrics I should be reading, what are they? IOPS?, Disk Read/Write B/sec?, etc...
Thank you,
Keith
