that's kind of a loaded question. You have physical drives that can so many iops  15k - 180 iops 10k - 130 iops 7200 - 80 iops  these are for random, small block workload. Now you also have a lot of cache in DMX/VMAX arrays that will make a lot of random workload appear as sequential and give you even more iops from those drives. If your array is already in production and you want to collect performance numbers, you have a couple of options:  SMC/SPA Performance Manager (part of ECC infrastructure) Solutions Enabler (symcli commands and stor daemons)  some of these will provide historical data, some current only.
Hi All,  I would like to know what is meant by what is meant by SAN IOP numbers of drives ?   Thanks,
