An embodiment of a semiconductor package apparatus may include technology to determine a stream classification for an access request to a persistent storage media, and assign the access request to a stream based on the stream classification. Other embodiments are disclosed and claimed.

Stream classification based on logical regions

A technology is described for a logical storage driver. An example method can include using the logical storage driver to: forward requests to a first storage stack for processing of an I/O workload associated with the I/O requests. Initiate generation of trace data for the I/O workload for collection and analysis to determine a second storage stack for improving performance of the I/O workload. Receive the storage processing logic for processing the I/O workloads using the storage configuration for the I/O workload, where the storage processing logic interfaces with the storage configuration. Intercept the I/O requests that correspond to the I/O workload. And, process the I/O workloads using the storage processing logic that interfaces with the storage configuration.

Logical storage driver

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.

Method and apparatus for erase block granularity eviction in host based caching

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

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.
