The survey of cache management in the shared storage environment

With the development of cloud computing, it needs high performance, availability and scalability of storage service. In shared storage environment based on the opening storage architecture, due to the inadaptability of the cache management, cache located on access paths provides performance acceleration, but limits availability and scalability of cloud storage system. This paper studies previous cache management technology of cluster or distributed system, and puts emphasis on availability and consistency, which bring down availability and scalability of cloud storage system. Moreover, this paper also analyzes the adaptability of previous cache management technology for shared storage environment.
