Battery Backup Unit

The battery backup unit (BBU) protects the data integrity of each storage controller. If both power supply units fail during a power outage, the system uses the BBUs for power and activates the asynchronous DRAM refresh (ADR) feature of the processors. While the BBUs supply power, cached data stored in the DRAM are written to the M.2 SSDs. This process is called Copy-to-Flash. Once power is restored and the system restarts, any logs, archives, or other important data are reconstructed from the data stored on the M. 2 SSDs.

Warning

During a power outage, do not remove storage controllers while their BBU status LEDs are orange. Removing a storage controller during this period interrupts the Copy-to-Flash process and may result in data loss.
