CACHE DESTAGING FOR VIRTUAL STORAGE DEVICES

摘要

Some implementations may include a virtual storage system to which data is written. The virtual storage system may include a cache and multiple hard drives. Multiple queues may be associated with the multiple hard drives such that each hard drive of the multiple hard drives has a corresponding queue of the multiple queues. A set of candidate rows may be selected from the cache. For each candidate row in the set of candidate rows, destination hard drives may be identified. Each candidate row may be placed in queues corresponding to the destination hard drives. Two or more candidate rows from the multiple queues may be written substantially contemporaneously (e.g., in parallel) to two or more destination hard drives.
