VMware vSphere OpenStack

ubercloud-iconVMware has been getting involved with the OpenStack Linux project over the last couple of years. They’ve created Hands On Labs geared towards OpenStack as well as creating the VOVA virtual Cloud Cluster appliance to make it easier for VMware administrators to get started with OpenStack. The VOVA appliance is not meant to be used in production. It is only a proof-of-concept appliance. It will allow VMware admins to deploy private clouds within their environments, though, and will give them insight into the OpenStack environment via vCenter. For more information on this see the OpenStack page on the VMware Developer Center site.

However, if you already know that you have instances where there are greater resources demanded than are available, you already know you need to configure resource allocation. Additionally, with your goal of virtualization consolidation being to push resource utilization up (maximizing your hardware investment) then you already know that you are taking the chance of maxing out your hardware (at some point) and the safe choice to make is to configure resource allocation. Let’s find out how.
