simultaneous infrastructure operations and the amount of shared storage?

I would like to know whether the simultaneous infrastructure operations' count is related to the amount of shared storage or not.

for VMmark 3.1, i'm planning to use iSCSI or SAN storage for the tests and if the simultaneous infrastructure operations is 4 in my lab environment, then should the amount of shared storage match this number(prepare 4 shared storage)?

Or the simultaneous infrastructure operations does not concern the  amount of shared storage at all?

is it only concern about the number of "DeployVMinfo"?

thanks in advance
