Single Homed or Dual Homed FEX

[dave cooper]

With the ability to do enhanced VPCs now on the FEXs is there any benefit to have a mixture of having of single attached FEXs and dual homed FEXs?

Here are some benefits as I see them

Single homed FEX is easier to trouble shoot as the topology is not as complex.

A dual homed FEX will support both dual attached hosts and a single attached host. So this means we only have one topology to deal with (everything dual homed)

Any other pros or cons?         

Thanks

If you have any servers with only one uplink, you want dual homed FEXes for redundancy.

Also, it depend on the number of FEXes you are connecting to the same set of switches.  For example: the max number of FEXes that can be uplinked to a set of 6k switches is 24 if you are dual homed, but if you are single homed the max is 48 (24 per switch).
