My most recent post Simple Example of Network Interface Virtualization generated enough interest and curosity to warrant a follow-up post showing simple uses cases for NIV. 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 [...]
A simple example of Network Interface Virtualization

My previous posts about NIV with Cisco’s Palo adapter were focused on the big picture and the complete solution, such as [...]

Cisco UCS and Nexus 1000V design diagram with Palo adapter
August 11, 2009 By 43 Comments
This is a follow-up and enhancement of a previous design diagram in which I showed Cisco UCS running the standard VMware vSwitch. In this post I am once again showing Cisco UCS utilizing the Cisco (Palo) virtualized adapter with an implementation of VMware vSphere 4.0, however in this design we are running ESXi and the [...]
Cisco UCS and VMWare vSwitch design with Cisco 10GE Virtual Adapter
July 5, 2009 By 26 Comments
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 [...]
Cisco UCS pricing response to Egenera
April 28, 2009 By 9 Comments
Egenera criticized Cisco’s math for UCS pricing in an article titled “A Closer Look at Cisco UCS pricing“. After reading the first few paragraphs of this article it became quite clear that Egenera needs a closer look at their own math. Let’s examine the flaws in the article… About the price of management software for [...]

How to Calculate TCP throughput for long distance WAN links
December 19, 2008 By 85 Comments
So you just lit up your new high-speed link between Data Centers but are unpleasantly surprised to see relatively slow file transfers across this high speed, long distance link — Bummer! Before you call Cisco TAC and start trouble shooting your network, do a quick calculation of what you should realistically expect in terms of [...]
VMotion on steroids with FCoE
August 14, 2008 By 5 Comments
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 [...]
