Ups - Hitachi CB 520H A1 User Manual

UPS

LPAR manager supports UPS by using Power management software which
running on the Guest OS. The Guest OS begins shut-down process when
receiving a request from UPS.
The LPAR manager begins shut-down operation after all of the Guest OSs
completed shut-down. And power status of Server Blade becomes off when
the LPAR manager has completed shut-down.
The Power management software has to be installed to the Guest OS for
controlling power of the Server Blade for LPAR manager. Control signal might
be delayed by network traffic when multiple Server Blades share one UPS.
Number of Guest OS managing from the UPS should be decided by
considering network traffic.
