A mass storage system made of flash electrically erasable and programmable read only memory (“EEPROM”) cells organized into blocks, the blocks in turn being grouped into memory banks, is managed to even out the numbers of erase and rewrite cycles experienced by the memory banks in order to extend the service lifetime of the memory system. Since this type of memory cell becomes unusable after a finite number of erase and rewrite cycles, although in the tens of thousands of cycles, uneven use of the memory banks is avoided so that the entire memory does not become inoperative because one of its banks has reached its end of life while others of the banks are little used. Relative use of the memory banks is monitored and, in response to detection of uneven use, have their physical addresses periodically swapped for each other in order to even out their use over the lifetime of the memory.

The invention is suitable for the field of storage and provides a file uploading method and device, and a mass storage system. The method comprises the following steps: a terminal device generates summary information corresponding to the file to be uploaded by using a preset summary information generating algorithm according to the file to be uploaded, and uploads the summary information to a storage server; the storage server searches whether the summary information uploaded by the terminal device exists or not; and when the storage server does not find the summary information, the terminal device uploads the file to be uploaded to the storage server. In the embodiment of the invention, the terminal device needs to upload the file to the storage server only when the file to be uploaded does not exist in the storage server, thereby reducing the data redundancy in the storage server, saving the network resources while uploading files and increasing the file uploading speed.

A method and apparatus for mirroring data stored in a storage device in a mass storage system by caching mirror coherency synchronization operation requests (break mirror and / or snapshot) from the operating system of a server and rapidly sending an acknowledgement to the server that the mirror operation has been completed. Thereafter, the mass storage system performs the flushing and mirroring processes to establish a mirror of the storage device at a time that is appropriate and convenient for the mass storage system to perform such mirroring. To facilitate such a mirror operation at a later time, the mass storage system may utilize a mirror table containing information concerning the mirror request. This information enables the mass storage system to subsequently flush the cache of data that is pertinent to a time before the mirror request occurred. Consequently, the mirror operation only mirrors data that would have been available for mirroring at the time the mirror request was received from the server. In this manner, the servers are not halted to facilitate mirroring and the mass storage system may mirror the storage device at a convenient time.

A fault-tolerant mass storage system includes two RAID controllers that communicate via a PCI-Express link. Each controller has a bus bridge coupled to the link, a cache memory that caches user data for storage on disk drives controlled by the controllers, and a CPU. The CPU fetches and executes program instructions from a CPU memory coupled to it. The CPU programs the bus bridge with window information defining a window of locations within the CPU memory, which is less than an entirety of the CPU memory. The bus bridge receives data on the link from the other controller and if the header of a packet containing the data indicates it is destined for the CPU memory, the bus bridge translates the address of the data so as to write the data safely to the CPU memory, but only within the window and nowhere else within the CPU memory.
