This as you may have guessed could potentially half the number of Network interfaces in your hosts (i.e. if there is any break in the traffic path on the primary fabric that the vNIC is mapped to then UCS Manager will immediately switch the data path to the other fabric, without the OS ever seeing the vNIC go down. Features that you may well already be aware of like Hardware Fabric Failover, where you can present a single vNIC to the OS / Hyper-visor and that vNIC is backed by Hardware fabric failover, i.e. But Cisco UCS does have some nice features which could greatly simplify the Hosts networking. What I mean by that is, the client may well have a Networking Standard for their ESXi hosts or want to use their standard host templates, which is fine. So the first question I tend to address with customers is how do they want their hosts networking to look.

which is equally relevant whatever platform is used and I’m sure you are familiar with. Ok, Thats narrowed us down but still a lengthy topic, so I’ll concentrate on the Cisco UCS specific aspects and not so much on the standard VMware config, I/O control etc. Lets take the most common implementation I tend to do which is vSphere using standard vSwitches. whether using Standard vSwitches / vDS, Nexus 1000V or VM-FEX. Thanks for the great question, and one (as you might expect) with potentially several answers depending on the implementation, i.e. Supported hashing options for load balancing:

The Windows teaming driver supports the below:

With regards to a bare metal install there is now a M81KR (Palo) NIC teaming driver for W2K8R2 available, which I have found works really well. I think the issue arises when you use a per packet / flow algorithm as the upstream LAN will see the host on Fabric A one minute then fabric B the next and the host will “flap” between the two. Again the answer is it depends, if you are using a Hyper-Visor like VMware you can select the hash algorithm to use and if you would like to active/active load balance as you suggest you would need to specify Port-Group based load balancing, this will ensure that each VM gets consistently mapped to the same UCS vNIC so VM 1 may go fabric A and VM 2 may go out Fabric B.
