Cisco Catalyst 4510 SUP V cant deal with iSCSI

My network team telling me DONT PUT iSCSI with Dell Equallogic or any iSCSI system, but I was telling them to do it and lets see how slow is goes.

So we plugged it all up and ran the stuff, running ok.. but when we doing a big SQL run the disk got disconnected. I could not belive it, I was thinking had to be a problem with the Dell Equallogic box.. I could understand it running slow, but disconnecting.

So we ordered in some Dell PowerConnect 5448 and they did the job and for a lot less then some new Cisco kit.

We started the final tests for upgrading from Microsoft Dynamics AX 4 to Microsoft Dynamics AX 2009. I hope to have some numbers for everbody.
