When I read the eWeek article entitled, "How to Manage Capacity in Virtualized Environments" I finished wanting more. Actually, I finished realizing TeamQuest already has more to offer.
Explaining the ITIL definition of Capacity Management is great, but how about expanding a bit further and drilling down into the details - from a Capacity Management perspective. Since the author, Rob Smoot, is a Group Product Marketing Manager at VMware, let's focus on VMware.
TeamQuest offers scalable, agentless performance data collection for both VMware ESX and ESXi hypervisors and:
TeamQuest Model, one tool in our suite, can predict performance in advance, help to optimize services and avoid costly bottlenecks altogether. We can find the least-expensive, best-performing configurations for P2V consolidation, ensuring that service levels will be met. IT managers can quickly determine the best way to allocate resources to VMware guests. And unlike other tools, TeamQuest Model understands response times inside virtual machines.
Take a look at a previous blog post entitled, "It's CRAZY to Run Just One App Per Virtual Server." Ron Potter, TeamQuest's Manager of Best Practices outlines the benefits of running multiple applications on a virtual machine and the planning needed to ensure you have the right configuration for the right situation. In fact, Potter takes this a step further in his white paper, "Grab More Post-virtualization Savings."
Also, check out the press release on TeamQuest's VMware capabilities, or our website on managing a virtual environment, or for some real nitty gritty details, see our white paper entitled, "Managing a Virtual Computing Environment - How TeamQuest Supports VMware's Virtual Machines."
Remember virtualization is not a cure-all. Capacity Management improves your virtualization tools. It's a discipline that, when used with the right tools, allows you to get the most from your virtualization efforts.
