On the rear, a Block and File VNX5500 platform includes the following hardware
components:
One dual 1U SPS
◆
One 3U DPE with two storage processors (SPs), each SP (A and B) having one CPU
◆
module and one power supply module
One to two 1U Control Stations
◆
One to two 2U Data Mover enclosures with one, two, or three Data Movers
◆
The Block and File (Unified) VNX5500 platform includes a dual 1U, 1.2-kilowatt standby
power supply (SPS) to maintain power to the Block and File (Unified) VNX5500 platform
SP during power loss. Within the SPS, a built-in DC battery pack is charged by way of an
AC-DC converter. AC input power from the power distribution unit (PDU) goes into the SPS
AC power inlet to the AC-DC converter. This converter then converts the AC power to DC
power, which is then stored in to the built-in DC battery pack. When emergency power is
needed by the Block and File (Unified) VNX5500 platform SP, a second DC-AC converter
