vSphere DRS Design for the Management Domain
vSphere Distributed Resource Scheduling (vSphere DRS) provides load balancing in a cluster by migrating workloads from heavily loaded ESXi hosts to ESXi hosts with more available resources in the cluster.
Automation Mode | Description |
|---|---|
Manual | vSphere DRS provides recommendations but an administrator must confirm the changes. |
Partially Automated |
|
Fully Automated | vSphere DRS automatically migrates virtual machines to fulfill certain criteria and automatically places workloads onto appropriate hosts at power-on operations. |
When using two availability zones, create VM-Host group affinity rules for the initial placement of virtual machines. These affinity rules ensure that virtual machines run in a single availability zone unless an outage event occurs. In this way, you avoid unnecessary vSphere vMotion migrations of virtual machines between availability zones.
