Abstract: A method of caching data is performed by a respective computer having one or more processors storing one or more storage management programs for execution by the one or more processors, non-volatile secondary storage and non-volatile cache memory. The method includes receiving from the non-volatile cache memory information identifying an amount of available storage in the non-volatile cache memory, and identifying a size of the management units in the non-volatile cache memory. The method further includes identifying write requests to write data to the non-volatile cache memory, sequentially writing to the non-volatile cache memory the write data for the identified write requests, to sequentially arranged locations in an address space of the non-volatile cache memory, and storing in memory metadata that maps the addresses or storage offsets of the write data to respective locations in the address space of the non-volatile cache memory.

Abstract: Examples of described systems utilize a cache media in one or more computing devices that may accelerate access to other storage media. A solid state drive may be used as the local cache media. In some embodiments, the solid state drive may be used as a log structured cache, may employ multi-level metadata management, may use read and write gating.
