Compaq Scalable UPS Card
The Compaq Scalable UPS card enables up to three UPS units to appear as a
single virtual UPS to the host computer. Compaq Power Management
Software gives users the capability to scale up the level of power protection
available to the system.
For example, connecting three Compaq R6000 UPS units to one Scalable UPS
card creates a virtual 18 kVA UPS. The virtual UPS would have nine
independently-controlled load segments.
