FAQs

What is a cache battery?

A cache battery is used to power the cache memory on a RAID controller or other hardware devices. It ensures that data in the cache is not lost in the event of a power failure.

What is the cache battery in the HP server?

In HP servers, the cache battery, often referred to as the Battery-Backed Write Cache (BBWC) or Flash-Backed Write Cache (FBWC), is a battery unit that provides power to the RAID controller's cache. It is important since it protects data during power outages.

What is the purpose of a RAID battery?

The RAID battery ensures that the data stored in the RAID controller's cache is not lost during a power failure by providing temporary power to the cache, allowing data to be written to permanent storage when power is restored.

Does cache affect battery life?

Cache does not directly affect the battery life of a device like a laptop or smartphone. However, in the context of RAID controllers, the presence of a cache battery is crucial for maintaining data integrity but does not significantly impact the battery life of the server itself.

What happens if the cache is removed?

If the cache is removed, the performance of the RAID controller can be significantly reduced because it can no longer temporarily store and quickly access frequently used data.

Additionally, there would be a higher risk of data loss during power failures, as the RAID controller would lose the ability to save unwritten data from the cache to permanent storage.
