ESX iSCSI design bottlenecks?
Posted on 2011-09-12
I have a high speed storage setup using 10gb CNA cards on the HOST to Fabric (nexus 5020)
The 5020 then connects to the NetApp 3240 ports e0a/e0b via 1gb cat6 cable.
I'm pretty sure this means that the HOST is accessing storage data at 1gb speeds through it's 10gb host adapter (CNA) card.
Am I missing something here? I'm pretty sure these iSCSI ports on this NetApp is 1gb. There is two on each controller for a total of 4. I think two in an ifgrp would net me 2gb?
If this is correct and I'm not taking advantage of 10gb capability for host to storage access, then would using the FC ports on the NetApp instead of e0a/e0b iSCSI ports and doing FChannel work better?
