In general, this disclosure is directed to techniques for adjusting a mapping between a logical block address (LBA) space and a physical block address (PBA) space based on offset data associated with a plurality of access requests. According to one aspect, a method includes defining a translation map between a plurality of LBAs and a plurality of PBAs for a data storage device. Each PBA is associated with a sequence of storage slots. The translation map maps each of the LBAs to a PBA and to an index of a storage slot associated with the PBA. The method further includes obtaining offset data for a plurality of access requests associated with the plurality of LBAs. The offset data includes information relating to the indices to which starting LBAs of the access requests are mapped. The method further includes adjusting the translation map based on the offset data.

Mapping alignment

The present disclosure provides a system and method for wear leveling. In one example, the method includes receiving first data to be stored to a first data storage medium and storing the first data to a first storage location in a nonvolatile data store of a second data storage medium comprising a solid-state memory. The method also includes setting a pointer to enable writing second data that is received to a next storage location in the nonvolatile data store. The next storage location comprises an address of the nonvolatile data store that is sequentially after an address of the first storage location. When the address of the first storage location is a last addressed location of the nonvolatile data store the pointer is set to enable writing the second data to a first addressed location of the nonvolatile data store. The method also includes writing the first data stored in the nonvolatile data store to the first data storage medium when a trigger occurs and preserving the pointer during the writing from the nonvolatile data store to the first data storage device such that the pointer enables writing the second data to the next storage location.

A bus-connected device includes a data storage element, a physical layer and a controller. The data storage element stores user data and multiple adaptations for multiple platform protocols. The physical layer uses at least a portion of a selected one of the multiple platform protocols to access the user data. The controller controls and communicates with the data storage element using a controller communication protocol that is neutral relative to the multiple platform protocols.

The present disclosure is directed to systems and methods of power management of a device. In a particular embodiment, the method includes determining a first power consumption value for a first power management operating sequence of an electronic device. The method also includes determining a second power consumption value for a second power management operating sequence based on previous activity of the electronic device. The method also includes selecting either the first power management operating sequence or the second power management operating sequence.

System and method of power management

A method, apparatus and program storage device for providing virtual disk service hints based storage. Virtual disk service hints are provided. The virtual disk service hints are analyzed to determine a configuration model to implement. The storage system is then configured according to the configuration model identified using the virtual disk service hint.

A system for backing up data includes a first computer configured to access a first storage device and a second computer configured to access a second storage device. In particular, the first storage device includes data to be backed up and the second storage device includes a snapshot of the data to be backed up. This system also includes a communications pathway between the first and second computers; and a backup application on the second computer which can backup the snapshot in response to a backup request initiated by the first computer.
