Method and apparatus for providing enhanced write performance using a buffer cache management scheme based on a buffer replacement rule

摘要

An approach is provided for improving write performance using a buffer cache based on a buffer replacement policy. A buffer cache manager is configured to improve address mapping scheme associated with write performance between an application system and a storage device system. The manager selects a victim page to be evicted from a victim block of a buffer cache according to a recently-evicted-first rule. And the victim block is selected associated with a log block of a memory.
