Hi,
How did you go with the configuration you proposed? Would be realy interested how you went on.
We have the exact same setup of a VMWare, UCS and VNX 5300 with iSCSI for both Boot and storage. We are having a really problem where logins to the VNX from the UCS blades are randomly logging out, this then hangs off for around 15 mins and then logs back in.
Are you going through a network switch from the VNX to the Fabric interconnects?
Regards
Andrew
