We currently have a redundant UCS setup with: 1. 2 x Fabric interconnects2. 2 x Chassis3. 2 x 3750e What we’ve noticed for the past 2 months is that the northbound connection from the fabric interconnect to the second 3750e would continuous go down after
A client gave me a call one evening asking me why he wasn’t able to access vCenter. The vCenter server was virtualized and run in a 7 ESX 4.0 host cluster on a redundant UCS setup (2 fabric interconnects, 2 chassis, 2 3750 switches). Seeing
