I just read an article "DataCore makes iSCSI rock", in which Randy Kerns was talking about SPC-1 iSCSI results. Why are they important? Why is there such a difference in SPC-1 iSCSI compared to peak I/O numbers on the same platform?
The SPC-1 benchmark creates a real-world database workload that was arrived at by using traces from many customer environments. It is a very controlled and repeatable test that is the best available for comparing performance from one product to another for that type of usage. The peak numbers are just what a storage device can do from cache and have no bearing on any real world activity. Basically, they are pretty useless. To learn more, go to
