Abstract
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.
