Shared Backup Power For Data Centers

摘要

In a data center having multiple resource zones, each of the zones has an uninterruptable power supply (UPS) and associated power storage elements such as batteries. A power bus may be provided between the resource zones to connect the outputs of the power storage elements of the resource zones. The power storage elements may thereby be shared between the UPS's so that an individual resource zone may be operated for a longer duration under anomalous conditions.
