FAQs

Q: How does a supercap differ from a traditional battery backup unit?
A: A supercap is a maintenance-friendly energy store with rapid charge/discharge and no typical battery replacement cycle.

Q: Does this preserve cached data indefinitely?
A: It supplies power long enough for the controller to write cache to non-volatile storage, protecting data until normal power returns.

Q: How do I know if the supercap needs replacement?
A: Check controller or CIMC health indicators for charge status and lifespan alerts.
