During the design of a new Cisco Data Center Network, a customer asked when VM-FEX would be used with Cisco Nexus 1000V Switch. Which scenario is most appropriate?
A. when a host must utilize a vSwitch and a distributed vSwitch
B. when using Non-UCS Servers to provide virtualization services with Nexus FEX modules
C. They are mutually exclusive of each other.
D. when a Cisco UCS C-Series server requires Cisco Nexus 1000V Switch to provide VM connectivity
1. VM-FEX Parent Switch (Controlling Bridge) could be
– Cisco 6100/6200 Fabric Interconnect : Support ESXi, Hyper-V and Redhat KVM
– Nexus 5500 switch, Nexus 6000 switch with VM-FEX license: Support ESXi
3. VM-FEX and Nexus 1000v are mutually exclusive on a single UCS blade. Also each VM-FEX interface is independnet and one could have both emulated and pass-through mode on the same VM
4. Both VM-FEX and Nexus 1000v utilize VEM mondule on ESX host but they are different binary files. VM-FEX VEM
could be donwloaded from driver ISO
