METHOD FOR ACCESSING A STORAGE SYSTEM WITH NUMEROUS FILE SYSTEMS

摘要

To avoid data collisions and conflicts when accessing a storage system with host and embedded file systems, file access commands may be received from the host and embedded file systems and translated to memory access commands. The memory access commands may write and read data with a memory on the storage system. Translating and executing the memory access commands centrally on the storage system preserves the integrity of the data in the memory. The embedded file system may receive the file access commands using the Universal Serial Bus Mass Storage Class interface from the host. Alternatively, a storage system index in the storage system includes a lock flag that indicates that portions of the memory are being accessed by the host and embedded file systems. The storage system index and copies of the storage system index may include modification flags to indicate whether the copies on the host and the storage system have been modified and need to be synchronized.
