Best Practices for Oversubscription of CPU, Memory and Storage in vSphere Virtual Environments
Virtualization enables administrators to efficiently share host resources among different applications. In fact, administrators often oversubscribe the physical resources on a host in order to maximize the number of workloads that can run on a host. However, physical servers may not always make use of the resources.
So how much oversubscription is too much?
This white paper discusses what oversubscription is and why it is used, explores the pros and cons of the practice, and proposes some ideas about the point at which oversubscription becomes dangerous.
