Abstract: SonD system is a new type computing environment based on network storage, which provides a simple method for deployment and management of computers in very large scale computing environment. The method of sharing cache between virtual storage devices in SonD system implements the memory cache sharing of the physical sharing data of virtual storage devices on file level, and efficiently avoids the problem of data consistency because of cache sharing. It is proved that the method improves the performance of SonD system efficiently.

Key words: SonD system, cache sharing, virtual storage device
