Hi All

I have a doubt in calculating oversubcription in an environment where i got to have nexus 2148T (FabEx) stacked on to nexus 5020 switch.

I m not sure about how do you calculate the bandwdith per server in this case coz you have 2 levels of stack happening in access layer.

I have a 3-tier architecture in place and in the access layer i have the mix up of both nexus 2148Ts and 5020s.

I dont have any probs in finding out oversubscription ratio and bandwidth per server to the servers connecected directly onto 4948/6500 which acts as access layer switches in few segments.

It will be great if someone here can throw some light on this calculation or atleast gimme a lead to do the calculation.
