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.

Abstract: In one embodiment, a request to access a first storage location of a storage device may be received, wherein the storage device comprises a data storage and a cache. The cache may be accessed to obtain data for one or more second storage locations of the storage device, wherein the data for the one or more second storage locations has not been written to the data storage, and wherein the first storage location and the one or more second storage locations are located near each other on the data storage. The data storage may then be accessed in response to the request to access the first storage location of the storage device. The data storage may also be accessed to write the data for the one or more second storage locations obtained from the cache.

Abstract: Systems and methods for issuing one or more write requests to a storage device, the system comprising one or more processors configured to generate one or more write requests, each write request comprising a respective data; tag each of the one or more write requests as a respective class from a plurality of classes, wherein the plurality of classes categorize data based on a rate at which it is written to the storage device; and issue the one or more write requests with their respective tags to the storage device, wherein the tag indicates to the storage device to write the first data proximate to data of the respective class within the storage device.

Abstract: A memory storage control apparatus, system, and method are described. An apparatus can include a memory controller configured to couple to a primary memory resource (PMR) and to a cache memory resource (CMR) and is configured to receive a read or write data request associated with particular data. For a read data request, the memory controller is configured to perform a lookup of a cache table mapped to the CMR for a copy of the particular data, and determine, if the lookup returns a hit and the particular data is not altered compared to the copy of the particular data, whether the CMR is saturated. For a write data request, the memory controller is configured to determine whether the CMR is saturated with data requests. In accordance with a determination that the CMR is saturated with data requests, the bypass the CMR, and send the data request to the PMR.

Abstract: In one embodiment, a request to access a first storage location of a storage device may be received, wherein the storage device comprises a data storage and a cache. The cache may be accessed to obtain data for one or more second storage locations of the storage device, wherein the data for the one or more second storage locations has not been written to the data storage, and wherein the first storage location and the one or more second storage locations are located near each other on the data storage. The data storage may then be accessed in response to the request to access the first storage location of the storage device. The data storage may also be accessed to write the data for the one or more second storage locations obtained from the cache.

Abstract: Provided are an apparatus and method for persisting blocks of data and metadata in a non-volatile memory (NVM) cache. A non-volatile memory (NVM) cache caches blocks of data from the storage of the first block size and metadata for each of the cached blocks of data indicating a status of the cached block of data, including whether the block of data is modified or unmodified, and a location in the storage where the block of data is stored. The non-volatile memory has blocks of a second block size greater than the first block size, wherein one of the blocks in the non-volatile memory stores the block of data from the storage and the metadata for the block of data. A cache manager writes the block of data and the metadata for the block of data to one of the blocks in the non-volatile memory cache and writes the block of data in one of the blocks in the non-volatile memory cache to the storage.
