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.

Cooperative write-back cache flushing for storage devices

Technology for an apparatus is described. The apparatus can include a memory controller with circuitry configured to define a caching and processing priority policy for one or more input/output (I/O) request class types. The memory controller can monitor one or more I/O contexts of one or more I/O requests. The memory controller can associate the one or more I/O contexts with one or more I/O class types using an I/O context association table. The memory controller can execute the one or more I/O requests according to the caching and processing priority policy of the one or more I/O class types. The apparatus can include an interface to the memory controller.

Efficient context based input/output (I/O) classification

An embodiment of a cache apparatus may include a first cache memory, a second cache memory, and a cache controller communicatively coupled to the first cache memory and the second cache memory to allocate cache storage for clean data from one of either the first cache memory or the second cache memory, and allocate cache storage for dirty data from both the first cache memory and the second cache memory. Other embodiments are disclosed and claimed.
