Abstract: A storage system includes a NAND storage media and a nonvolatile storage media as a write buffer for the NAND storage media. The write buffer is partitioned, where the partitions are to buffer write data based on a classification of a received write request. Write requests are placed in the write buffer partition with other write requests of the same classification. The partitions have a size at least equal to the size of an erase unit of the NAND storage media. The write buffer flushes a partition once it has an amount of write data equal to the size of the erase unit.

Abstract: 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.

Abstract: A method and apparatus for caching data accessed in a storage device, which include a selection of a list from a plurality of lists based on a cache block accessed from a cache memory, the cache memory being partitioned into a plurality of cache portions, each of the plurality of lists being assigned to a respective cache portion of the plurality of cache portions, each of the plurality of lists indicating an order in which cache blocks of the respective cache portion were accessed. Furthermore, a determination as to whether the accessed cache block meets a list update criteria, and an update the order in which cache blocks, assigned to the selected list, were accessed from the cache memory based on determining the accessed cache block meets the list update criteria may be included.

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.
