  • Method and apparatus for erase block granularity eviction in host based caching
    Patent number: 10402338
    Abstract: In one embodiment, a processor comprises a processing core; and a cache controller to send a plurality of write requests to a cache storage device to store cache lines of a stream block, the plurality of write requests each including a stream identifier of the stream block, wherein a capacity of the stream block is equal to a capacity of an erase block of the cache storage device and wherein the erase block is dedicated to storing cache lines of the stream block; determine to evict the stream block from the cache storage device based upon a determination that space is not available in the cache storage device to cache data received from a first storage device; and send a deallocation request to the cache storage device to deallocate all cache lines of the stream block to enable the cache storage device to erase the erase block.
