Optimization is key to proper server virtualization and a key component is the shut down plan in the event that you lose power. The easiest and best way to initiate shutdown is at the host level through UPS software that way you only have one location to manage and initiate shutdown.
While you may not be able to tolerate downtime and have a redundant IT infrastructure in place for that very reason, the worst case scenario can (and does) happen. You can use your UPS software to initiate a virtual move during a power outage.
You should choose solutions that work together. A software solution will help you monitor systems with ease. The use of a virtual dashboard in order to initiate a shutdown or virtual machine move when necessary can be managed by Eaton’s Intelligent Power Manager (IPM) software.
