Hello,
I've got 3 hosts all connected to 3 shared 2TB datastores via iSCSI. If I want to verify the performance of each datastore, as well as the storage performance of each host, would it make sense to just have each host talk to one datastore (since they share paths) or should I test with each host hitting each datastore? I would think having multiple hosts talk to multiple datastores would make it easier to isolate host specific issues but I imagine most issues exist at a higher level than specific host issues (inadequate or misconfigured hardware vs. a bad NIC or something).
Thanks.
