Hi! I have a questions about Cisco Adapter FEX and VM Fex. As i understand, Cisco Adapter FEX gives multiple vNIC on one mezzanine card, and each of them appears as virtual port on Fabric Interconnect. Also, same thing for VM-FEX, each VM NIC appears as virtual port on Fabric Interconnect.
VM-FEX (previously known as VN-link) is a method to extend the network fabric completely down to the VMs. With VM-FEX, the Fabric Interconnects handle switching for the ESXi host's VMs. UCSM utilizes the vCenter dVS Application Programming Interfaces (API) to this end. Therefore, VM-FEX shows as a dVS in the ESXi host.
There are many benefits to VM-FEX:
Reduced CPU overhead on the ESX host
VMware DirectPath I/O with vMotion support
Network management moved up to the FIs rather than on the ESXi host

Cisco Documents are usually accurate, but when it came to the document
on Cisco APIC Signature-Based Transactions it was slightly off the mark.
