Chapter 11Managing Resource Allocation
The ability for a single physical server to host many virtual machines (VMs) has a massive value in today's modern datacenters. But let's face it: there are limits to how many VMs can run on a VMware ESXi host. To make the most of the platform, you need to understand how the four key resources—memory, processors, disks, and networks—are consumed by the VMs running on the host, and how the host consumes those resources. The methods used to arbitrate access to each of these resources on an ESXi host are a bit different. This chapter discusses how an ESXi host allocates these resources and how you can change the way these resources are consumed.
