System Capacitor Unit (SCU)
A SCU is installed in a controller as a backup power source in case of power outage.
The SCU is charged from an external power source while the ETERNUS DX Disk storage
system is running normally. If a power outage is detected, data in the cache memory is saved to
the non-volatile memory in the controller using the SCU. The saved data is retained in the non-
volatile memory indefinitely.
