Abstract
A data management device includes a cache for a data storage device and a processor. The cache includes cache devices that store a block set. The processor obtains a cache modification request that specifies a first block of the block set, updates a copy of a header of the block set in each of the cache devices based on the modification request, updates a copy of meta-data of the block set in each of the cache devices based on the cache modification request, and updates the first block in a first cache device of the cache devices based on the cache modification request.
