Anyway, for most of the time we (the Cisco team) focused on Flex-10’s total lack of [...]

NIV takes a single physical adapter and presents multiple virtual adapters as if they were physical adapters to the server and network.  Now that the server and network see multiple [...]

I’m seeing some confusion in the blogosphere about how Cisco’s implementation of Network Interface Virtualization (NIV) really works so perhaps a very simple example is needed, and that is the intent of this post.  My previous posts about NIV with Cisco’s Palo adapter were focused on the big picture and the complete solution, such as [...]

This diagram is a sample design of Cisco UCS running vSphere 4.0 utilizing the VMWare vSwitch and Cisco’s virtualization mezzanine adapter.  The Cisco adapter is a dual port 10GE Converged Network Adapter supporting Fibre Channel over Ethernet (FCoE) and Network Interface Virtualization (NIV).  The Cisco adapter is “virtual” in the sense that this single physical [...]

Want lightning fast VMotion? Just install a CNA (Converged Network Adapter) from Emulex or QLogic and connect it to a Cisco Nexus 5000.
Mario Apicella of InfoWorld did just that and writes:

“I had intended to post a movie clip of the test VM moving to the new ESX server using VMotion, but the action [...]
