EMC VNX SERIES STANDBY POWER SUPPLY (SPS) / REPLACEMENT BATTERY 078-000-062

As shown in Figure 1, the SPE uses one 1.0-kilowatt SPS to maintain power to the storage system during a power loss to allow for a full dump of the write cache to a reserved area on persistent disk. An additional SPS can be added for further redundancy

When only one SPS is used, the power output connectors for the SPS supply power to SP A and the first DAE on the first back-end loop. The power for SP B and the remaining power to the first DAE on the first back-end loop are supplied by the PDU within the CLARiiON 40U rack.

When two SPSs are used, the power output connectors from the additional SPS power both SP B and the first DAE.

Figure 1. View of EMC VNX Standby Power Supply (SPS) 078-000-062

It is important to cable each SPS so it connects completely to either the A side or the B side. For example, if you are looking at the SPS from the back, they should be configured as follows:

  •   ::  SPS on the right: Power-out and sense cables should connect to power supply A and SP A.
  •   ::  SPS on the left: Power-out and sense cables should connect to power supply B and SP B (optional).

If an SPS is cabled with the SPS sense cable going to SP A and the power-out cable going to power supply B (or vice versa), error conditions are displayed when the SPS is tested while it is charging.

**Please note: EMC VNX SPS 078-000-062 is not a UPS**

The SPS is just to protect the write cache. I am saying "just" because this component is not an UPS at all. If there is a power failure  it will allow the cache to be flushed to the vault disks hence avoiding data to be lost/corrupted.

In theory, its this simple. 

Each SPS has two batteries. One SPS provides backup power to the SPE, and the second to the first DAE. These SPSs provide enough power to each storage processor and first DAE to ensure that any data in flight is de-staged to the vault area in the event of a power failure, guaranteeing no writes are lost. When the array is restarted, the pending writes are reconciled and persisted.

This process is only a few minutes.
