Balance Workloads

• The data center went from one four hypervisors to handle the additional load

• Additional Hypervisors were started to maintain the pool of two standby

• Click the Configure button and select the Demo Load command

29

• The Demo command adds load on hypervisor 03 and the CPU utilization spikes past the upper limit of 70%

30

• VMs are migrated away from host 03 to balance the workload

• VMs are started on the standby host and another host is powered on to maintain the two host Standby pool

Manage Workloads

• Put a host into Maintenance mode

• The running VMs are automatically migrated and load balanced on other hosts

• To put the host into maintenance mode, click the Actions button and select the Enter Host Maintenance command

32

• The VMs running on host 03 are automatically migrated and load balanced on other hosts

• Additional host is started and put into standby mode to main the pool of two

Protect Workloads

• Select the Configure button and select the Demo PFA command to create a PFA

• Click the Alarm icon to see the nature of the error

• The system will automatically migrate and balance the VMs on other hosts

• The automatic VM migration is a function of the High Availability policy. If a host crashes or losses power the HA policy will re-parent the VMs onto other hosts
