Abstract
A storage server includes an IO controller, a management controller and physical drives. The IO controller generates multiple metadata updates and writes a cache entry that includes the multiple metadata updates to a first cache in memory of the management controller. The IO controller additionally writes a copy of the cache entry to a second cache in a memory of the IO controller and increments a commit pointer in the first and second caches to indicate that the metadata updates are committed.
