An apparatus includes a computing node and a metadata server. The computing node may transmit a request to open a file to the metadata server, which may provide a corresponding file identifier to the computing node. The computing node may use the file identifier to directly access the storage storing the file. In one embodiment, the storage may be an object-based storage. The storage may receive the file identifier with an access command and may perform the mapping from file identifier to storage blocks internally. Thus, accesses to the storage may be performed on an arbitrary boundary within the file. In other words, the entire block including the data needed by the computing node may not be transferred to the computing node. Instead, the storage may select the data requested from the file (e.g. via an offset and a number of bytes or some similar mechanism) and return that data to the computing node.

A distributed backup system for a networked computer system is disclosed such that when a data backup is created, a client backup application stores backup restore information as part of the backup data which can be interpreted by the backup application and/or backup server to direct how the remainder of the backup data needs to be restored. The backup restore information may be stored (cached) in staging directory, e.g. on the local computer system. During a backup restore process, the backup application first whether the backup restore information exist in the staging directory before requesting them from the backup server. The backup restore information may be stored in a unique location within the staging directory, e.g. a timestamp-labeled subdirectory. The backup application reconciles the staging directory to eliminate backup restore information for backup data that no longer exists on the backup server.

Disclosed is a system, method, and an article of manufacture for preferentially keeping an uncopied data set in one of two storage devices in a peer-to-peer environment when data needs to be removed from the storage devices. Each time a data set is modified or newly created, flags are used to denote whether the data set needs to be copied from one storage device to the other. The preferred embodiments modify the timestamp for each uncopied data set by adding a period of time, and thus give preference to the uncopied data set when the data from the storage device is removed based on the least recently used as denoted by timestamp of each data set. Once the data set is copied, the timestamp is set back to normal by subtracting the same period of time added on when the data set was flagged as needing to be copied.

A cluster of computer system nodes connected by a storage area network include two classes of nodes. The first class of nodes can act as clients or servers, while the other nodes can only be clients. The client-only nodes require much less functionality and can be more easily supported by different operating systems. To minimize the amount of data transmitted during normal operation, the server responsible for maintaining a cluster configuration database repeatedly multicasts the IP address, its incarnation number and the most recent database generation number. Each node stores this information and when a change is detected, each node can request an update of the data needed by that node. A client-only node uses the IP address of the server to connect to the server, to download the information from the cluster database required by the client-only node and to upload local disk connectivity information.

The invention provides a balance method for circulatory rewriting and flashing used in a solid state disc. During each operation, new data are written in a physical block which is used seldom, and the physical block is called a main block; when the data needs to be replaced, the renewed data are written in another new physical block, and the physical block is called a replacement block; when the replacement block is fully written, the effective data in the main block and the effective data in the replacement block are transported to a new physical block, and the new physical block is a new main block; and the previous main block and the previous replacement block are chained to a waste block chain. By adopting the method provided by the invention, the storage mediums of the entire solid state disc lose evenly and the balance of the erasable time of each block when the data blocks are chosen by write data is ensured, thereby prolonging the service life of the solid state disc.

Cache prefetching algorithm uses previously requested address and data patterns to predict future data needs and prefetch such data from memory into cache. A requested address is compared to previously requested addresses and returned data to compute a set of increments, and the set of increments is added to the currently requested address and returned data to generate a set of prefetch candidates. Weight functions are used to prioritize prefetch candidates. The prefetching method requires no changes to application code or operation system (OS) and is transparent to the compiler and the processor. The prefetching method comprises a parallel algorithm well-suited to implementation on an application-specific integrated circuit (ASIC) or field-programmable gate array (FPGA), or to integration into a processor.

A computer system includes an SSD as swap space for a database management system that comprises a primary database engine and at least one clone database engine. A queued database transaction is sent to the clone database engine for pre-processing while the primary database engine is processing a current database transaction and if data needed to process the queued database transaction is not currently cached in the computer system, the clone database engine fetches the data and caches it into a buffer accessible by the primary database engine. When the primary database engine is ready to process the queued database transaction, it will be able to access the needed data without accessing the SSD, thereby avoiding delays resulting from accessing the SSD.
