Not all data centers are created equal
This article is part of the Virtual Data Center issue of February 2012, Vol. 37
Technology changes constantly, but not every new development or new product is a must-have. But virtualization is different. It is a game changer, and it’s captivated a lot of virtual data center managers. We’re now well established in this new virtual world, and there are plenty of new challenges, along with new improvements. One thing that virtual data center managers may have noticed is that their work is never done. (OK, you probably already knew that.) But when it comes to virtualization, there’s always tweaking and optimizing to do. Virtualize your SQL or Exchange server, and you’ve got better utilization and mobility. But, now you’ve also got to allocate enough memory and make sure these mission-critical apps aren’t competing for resources. Over consolidation and low utilization can really get in the way of efficiency efforts. In this issue of Virtual Data Center, contributor Brien M. Posey reminds us that not all virtual machines are created equal. The corollary to that may be that not all data centers, or data center ...

The push for high utilization can cause serious VM performance issues, but proper VM resource allocation can prevent server over-consolidation in virtual data centers.
