Calculate /Measure Performance on EV4100 connected to Linux servers

Hello,
we have a EVA 4100 48 x 15K 146 GB FC disks .
How can I calculate theoretical max radmom
write IOPs ? Is there a general formula available ?
As we have 3 Linux Servers connected :Can I use /proc/diskstats output ( Field 8 writes completed) to see how much write performance reserve is left over ? Does this approach makes sense ?
Thanks in advance
Thomas
