© 2012 IBM Corporation Platform Computing 27 Start and additional 100 VMs to add load to the system The VMs are powered on, registered and ready for use Select the Hypervisor Hosts table to see changes to their states

© 2012 IBM Corporation Platform Computing 28 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

© 2012 IBM Corporation Platform Computing 29 The Demo command adds load on hypervisor 03 and the CPU utilization spikes past the upper limit of 70%

© 2012 IBM Corporation Platform Computing 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

© 2012 IBM Corporation Platform Computing 31 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

© 2012 IBM Corporation Platform Computing 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

© 2012 IBM Corporation Platform Computing 33 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
