Abstract: A method includes monitoring a number of read access requests to an address for data stored on a backing store. The method also includes comparing the number of read access requests to a read access threshold. The read access threshold includes a threshold number of read access requests for the address. The method also includes caching data corresponding to a write access request to the address in response to determining that the number of read access requests satisfies the read access threshold.

Abstract: Apparatuses, systems, methods, and computer program products are disclosed for destaging cached data. A method includes caching write in a nonvolatile solid-state cache by appending the data to a log of the nonvolatile solid-state cache. The log includes a sequential, log-based structure preserved in the nonvolatile solid-state cache. A method includes destaging at least a portion of the data from the nonvolatile solid-state cache to the backing store in a cache log order. The cache log order comprises an order in which the data was appended to the log of the nonvolatile solid-state cache.

Abstract: An apparatus and system are disclosed for a storage area network (“SAN”). In one embodiment, a computer system includes an internal storage device and an internal storage controller. In this embodiment, the internal storage controller is configured to implement a SAN that includes at least the internal storage device and a storage device external to the computer system. In this embodiment, the internal storage controller is further configured to service a storage request received from a client that involves data stored by the internal storage device. In this embodiment, the internal storage controller is configured to communicate with the external storage device via a network.

Abstract: Apparatuses, systems, and methods are disclosed for managing cache pools. A storage request module monitors storage requests received by a cache. The storage requests include read requests and write requests. A read pool module adjusts a size of a read pool of the cache to increase a read hit rate of the storage requests. A dirty write pool module adjusts a size of a dirty write pool of the cache to increase a dirty write hit rate of the storage requests.

Abstract: An apparatus, system, and method are disclosed for managing eviction of data. A cache write module stores data on a non-volatile storage device sequentially using a log-based storage structure having a head region and a tail region. A direct cache module caches data on the non-volatile storage device using the log-based storage structure. The data is associated with storage operations between a host and a backing store storage device. An eviction module evicts data of at least one region in succession from the log-based storage structure starting with the tail region and progressing toward the head region.
