I have put in a few UCS Blade chassis, but this was a few years back, and each system was pretty simple - a pair of FI's and a single chassis. Nothing special. All that was needed was UCSM for the single domain and single chassis.
I am putting in a new system, and, like the others, it is just a single chassis (just with UCS Mini this time around). The blades that we ordered required that UCS Director be purchased, and the blades themselves came with Cisco One licensing.
So my question, as the subject eluded to, is the UCS Director truly required for this type of setup which won't require data center automation beyond what VMWare itself will handle? Does it somehow tie into licensing or something that we can't go without? It seems like a waste to take the time to setup the appliance and get it all configured just to sit and do nothing but take up resources. This customer does not make changes very often.
