Chapter 3 OverviewThis is done by managing and monitoring the hardware for a power event. The UPM softwarecan take action in one of the following ways:Load Shedding:• Initiate a virtual machine migration if a host server experiences a power event• Initiate a Virtual Machine (VM) suspension or shutdown of VM of less priority whilekeeping more critical VMs live• Gracefully shut down all VMs and its host server to keep more critical host/VM serverslivePower Capping:Set user defined power budget as part of a disaster avoidance plan to guarantee aminimum amount of battery run time during a power outage. The power budget ismaintained by using the load-shedding capabilities discussed above. It does not affectsystem performance by reducing processor frequency. Power capping only maintainssystem load by managing load shedding capabilities.Move Critical Machines to Back-up SiteThe UPM will read environmental (temperature over the limit) or UPS power alarms(utility power loss) and will work with VMware's Site Recovery Manager (SRM) toinitiate a disaster recovery plan to initiate a move of critical applications to a back-updata centre location or disaster recovery (DR) site.Differences between UPP and UPMAttention! The UPP and UPM software can not be installed on the same server at the same time.Doing so will lead to unpredicted operation of either software or the UPS unit. In such asituation support can not be provided and one of the applications has to be uninstalled.The UPP software can only be used as a stand-alone software on a single host. The UPMsoftware can be used to manage multiple hosts. The UPM software also has additionalfeatures.
