OPPORTUNISTIC ASYNCHRONOUS DEDUPLICATION USING AN IN-MEMORY CACHE

摘要

Examples perform asynchronous deduplication of storage, such as virtualized or physical disks. Incoming input/output (I/O) commands containing data are subdivided into blocks which are written both to storage and to an in-memory cache. As idle processing resources become available, deduplication is performed on the storage using the in-memory cache. In this manner, read operations from storage are avoided in favor of the read operations from the in-memory cache.

1. A method for asynchronous deduplication of storage using an in-memory hash cache, said method comprising:
receiving, by a computing device, a plurality of input/output (I/O) commands, said plurality of commands including content subdivided into a plurality of blocks of data; writing the plurality of blocks both to storage and to the in-memory hash cache; and subsequently performing asynchronous deduplication of the storage using the in-memory hash cache.
