My partner-in-crime, Brian Johnson, and I have just finished a new White Paper detailing some best practices when using 10 Gigabit Ethernet with VMware* ESX/ESXi. This is the 3rd paper in a series that began with Brian’s well-received and many times re-branded paper entitled Simplify VMware vSphere* 4 Networking with Intel® Ethernet 10 Gigabit Server Adapters that I blogged about here in July. This paper detailed some best practices regarding how to improve efficiency and simplicity by moving to two 10 Gigabit Ethernet connections on a virtualized server rather than multiple 1 Gigabit ports.
We continued the series with another White Paper entitled Virtual Switches Demand Rethinking Connectivity for Servers, which discusses how the virtual switch within VMM can now be thought of as having uplinks from your Virtualized Server in a VM to the virtual switch, which in turn has physical uplinks to the top-of-rack switch; this paper is located here.
This latest paper modifies some of the best practices discussed in the 1st paper to utilize some of the new Quality of Service capabilities in the Virtual Distributed Switch in VMware vSphere 4.1. We discuss how and why those practices have been updated and provide some additional best practices that can be applied to a virtualized environment.
