Abstract
A network storage server has a non-volatile mass storage facility, a main cache and a victim cache. A technique of efficient, non-blocking storage of data in the victim cache includes, responding to a caller process by, without blocking the caller process, selecting a first storage unit for eviction from the main cache, destaging the first storage unit for storage in the victim cache without copying the first storage unit, and identifying a second storage unit to the caller process as available to be overwritten in the main cache.
