One of the things we talk about in Cisco UCS is how easy is it is to expand the architecture. Each time you add a chassis in competing solutions, you have lots of management points to configure – the chassis itself, the Ethernet and potentially Fibre Channel switching/connectivity, etc. With UCS, it’s simply a matter of “telling” the Fabric Interconnects that the chassis is there and the rest happens auto-magically. At HealthITGuy’s Blog, Michael Heil posts his experience in adding a new chassis to a running UCS deployment. The rest of his posts on UCS, from a customer’s perspective, are also excellent.
