Harnessing vSphere Performance Benefits For NUMA: Part 2

In my last post I talked a great deal about native support for NUMA in vSphere on enabled Opteron and Nehalem processor platforms. NUMA is a strong technology in and of itself, but it really starts to shine when teamed with other supporting technologies. In this post, I'm going to cover the details of integrating next generation networking and interrupt technologies to improve storage and networking performance. I'll focus on MSI-X, but future posts will cover VMDq, RSS and Multiple Queue's in m

The main barriers to improving performance with these technologies exist in making sure that the new systems that you roll out are specified correctly. MSI-X as well as NUMA and Intel VMDq are all handled automatically by vSphere provided that the technologies are present and turned on. Getting the most out of these core server technologies requires an understanding of how they work, what they do and how to put together a spec that takes advantage of these facts.
