Cell RAM cache is a cache in front of the Flash Cache on storage servers and is extension of the database cache. It is faster than the Flash Cache, but has smaller capacity.

- What is adaptive scrubbing?
Oracle Exadata System Software automatically inspects and repairs hard disks periodically when the hard disks are idle. The default schedule of scrubbing is every two weeks.
- In event of storage server failure how RAM cache works?
In the event of storage server failure on the primary mirror, the database sends the RAM cache population to the secondary mirror, so that the blocks are now cached in the RAM cache for the secondary mirror. When the primary mirror comes back to online state, the blocks are populated back in the primary mirror’s RAM cache.
