What to do next

You have completed setup for a single-host management system in which ESXi is used to run virtual machines.

Explore the advantages of managing multiple hosts with vCenter Server.

Managing Multiple Hosts with vCenter Server

You can deploy VMware vSphere with vCenter Server to manage multiple hosts at the same time.

Using vCenter Server to manage multiple hosts allows you to experiment with advanced management options,

such as resource sharing, and all of the other options available within the vSphere environment.

Deploying vCenter Server provides many advantages over deploying a single, standalone ESXi host. Table 1

illustrates some of the advantages and compares multiple-host management with vCenter Server as opposed

to single-host management.

vSphere and vCenter Server

VMware vSphere is a suite of virtualization applications that includes ESXi and vCenter Server.

vSphere uses virtualization to do the following tasks:

Run multiple operating systems on a single physical machine simultaneously.

Reclaim idle resources and balance workloads across multiple physical machines.

Work around hardware failures and scheduled maintenance.

vSphere includes the following components in addition to the ESXi host and vSphere Client you have already

setup:

VMware vCenter Server

vCenter Server unifies resources from individual hosts so that those resources

can be shared among virtual machines in the entire datacenter. It accomplishes

this by managing the assignment of virtual machines to the hosts and the

assignment of resources to the virtual machines within a given host based on

the policies that the system administrator sets.
