VKernel, now part of Dell Software, and the award-winning provider of enterprise-class capacity management and performance monitoring products for virtualized data centers and cloud environments, announced today a new resource that helps virtualization administrators and data center managers maximize resource utilization while maintaining peak performance in their environments. A new white paper available today, “Best Practices for Oversubscription of CPU, Memory and Storage in vSphere Virtual Environments,” details the benefits and challenges of virtualization resource management as well as the most effective way to leverage oversubscription practices.

Server virtualization enables dramatic increases in efficiency in the datacenter.  The ability for multiple virtual servers to share the same underlying physical resources sets the stage for dramatic reductions in physical server counts and corresponding capital and operating costs.  But how far should this sharing be pushed?  At what point does the sharing of resources become dangerous?

VKernel’s new white paper, “Best Practices for Oversubscription of CPU, Memory and Storage in vSphere Virtual Environments,” discusses methods for effectively managing oversubscription of CPU, memory and storage resources. The paper addresses the pros and cons of oversubscription and, based on a number of real world discussions, proposes ideas about the point at which oversubscription becomes dangerous. This paper also explains how VKernel’s free tool, vOPS Server Explorer, provides at-a-glance information about oversubscription as well as insight into the overall performance and capacity of your virtual environment.

“Oversubscription of shared resources is necessary to maximize ROI of virtual environments,” says Mattias Sundling, vExpert and Evangelist at Dell Software. “This new white paper gives admins the insight needed to leverage oversubscription without risking costly outages and maintaining optimal performance in their virtual environments.”
