EMC 078-000-085 1200W SPS Standby DC Power Supply

The EMC SPS Standby DC Power Supply provides battery power and allows storage processors to de-stage data in-flight to the vault area of the reserved space in the event of a power failure. Once power is restored to the array, any writes that were de-staged are reconciled and persisted to the target backend disks to ensure no loss of data. It supports the EMC CX4-120, CX4-240, CX4-480, DL5100, NS-120, NS-480, VNX5100, VNX5300, VNX5500, VNX5700 and VNX7500 platforms.
