vpc questions

I was going through the VPc documentation and stumbled upon this

Single Homed Fabric Extender vPC Topology

The               Cisco Nexus 5000 Series             switch can support up  to 12 configured single homed Fabric Extenders (576 ports) with this              topology however only 480 dual homed host servers can be  configured in a vPCs with this configuration.

Is there a specific reason for supporting just 12 single homed FEX

How does the calculation of 480 dual homed servers is arrived

Re: vpc questions

Control Plane will get over loaded over 480 Port-channels. so 480 is the supported max while 576 is the theoritical max.
