Abstract: A data storage device includes one or more storage media that include multiple physical storage locations. The device also includes at least one cache memory having a logical space that includes a plurality of separately managed logical block address (LBA) ranges. Additionally, a controller is included in the device. The controller is configured to receive data extents addressed by a first LBA and a logical block count. The controller is also configured to identify at least one separately managed LBA range of the plurality of separately managed LBA ranges in the at least one cache memory based on LBAs associated with at least some of the received data extents. The controller stores the at least some of the received data extents in substantially monotonically increasing LBA order in at least one physical storage location, of the at least one cache memory, assigned to the identified at least one LBA range.

Abstract: A method for data steering in tiered storage is described. In one embodiment, the method includes ranking storage areas of a storage device according to latency of access. In some embodiments, the storage areas include at least a first storage area and a second storage area. The method includes identifying first data at the storage device, passing a portion of the first data through a compression algorithm, and analyzing a result of passing the portion of the first data through the compression algorithm. In some cases, the result includes a score of compression savings associated with the portion of the first data. If the result satisfies a threshold associated with the first storage area, the first data is stored in the first storage area. If the result satisfies a threshold associated with the second storage area, the first data is stored in the second storage area.

Abstract: In one embodiment, a method is operable in an over-provisioned storage device comprising a cache region and a main storage region. The method includes compressing incoming data, generating a compression parameter for the compressed data, and storing at least a portion of the compressed data in chunks in the main storage region of the storage device. The method also includes predicting when to store other chunks of the compressed data in the cache region based on the compression parameter.

Abstract: A method for data steering in tiered storage is described. In one embodiment, the method includes ranking a plurality of storage areas of a storage device according to at least one property of the plurality of storage areas. In some embodiments, the plurality of storage areas include at least a first storage area and a second storage area. The method includes obtaining a sample of data at the storage device, passing the sample of data through one or more compression codecs, and analyzing a result of passing the sample of data through the one or more compression codecs. In some embodiments, the result includes a score of compression savings associated with the sample of data. The method includes storing the data in one of the plurality of storage areas based at least in part on the analyzing the result of passing the sample of data through the one or more compression codecs.
