Create Clusters
A cluster is a group of hosts. When a host is added to a cluster, the host's resources become part of the cluster's
resources. The cluster manages the resources of all hosts within it. Clusters enable the vSphere High
Availability (HA) and vSphere Distributed Resource Scheduler (DRS) solutions.
Prerequisites
n
Open vSphere Client session to a vCenter Server.
n
Verify that you have sufficient permissions to create a cluster object.
n
Verify that a Datacenter, or folder within a datacenter, exists in the inventory.
Procedure
1 Right-click a datacenter or folder in the vSphere Client and select New Cluster.
2 Enter a name for the cluster.
3 Choose cluster features.
Option Description
If you chose to use DRS with this
cluster
a Click the vSphere DRS box.
b Select an automation level and a migration level and click Next.
c Select a default power management setting and a DPM threshold, and
click Next.
If you chose to use HA with this
cluster
a Click vSphere HA.
b Select whether to enable host monitoring and admission control.
c If admission control is enabled, specify a policy.
d Click Next.
e Specify cluster default behavior and click Next.
f Specify virtual machine monitoring settings and click Next.
4 Select an Enhanced vMotion Compatibility (EVC) setting and click Next.
EVC ensures that all hosts in a cluster present the same CPU feature set to virtual machines, even if the
actual CPUs on the hosts differ. This prevents migrations with vMotion from failing due to incompatible
CPUs.
