Abstract: A network storage system for a download intensive environment is provided. The network storage comprises at least a data storage server (DSS) that includes an interface enabling connection of the DSS to a network at a location that enables at least a view of network transactions performed by a plurality of clients; a storage unit; and a system adapted to monitor the network transactions occurring on the network and identification of the network transactions as belonging to a registered client of the DSS, and storing in the storage the transactions with an identification corresponding to the registered client.

Abstract: A method and apparatus for transferring data between a main volatile memory and a backup memory in a redundant system comprised of a main sub-system and a mirror sub-system is provided. For the purpose of preserving uninterruptible power supply energy, data is continuously transferred to back-up memory which may be a corresponding volatile memory of the mirror sub-system, or a non-volatile memory of the main sub-system. The method further includes the steps of detecting a loss of system power, transferring data from volatile memory to non-volatile memory, and turning off the power supply of the non-volatile memory module. The method is capable of detecting the status of the uninterruptible power supply of the mirror system and if that system is operative then only data not previously backed up is transferred to main non-volatile memory; otherwise, if a power failure is detected in both sub-systems all data in volatile memory, not previously written to non-volatile memory is transferred to non-volatile memory.

Abstract: Independent nodes (66) providing storage services can be networked together, such that client devices (60, 61) can be attached to any independent node (66c, 66d), while independent nodes (66) identify themselves to client devices (60, 61) uniformly. Each independent node (66) would have the same name, address or other identification data with respect to each client device (60, 61). When data stored in a specific independent node (66) are accessed by a client device (60, 61) connected to a different independent node (66c, 66d), the request is forwarded to the independent node that where the requested data is stored. That independent node (66) can either respond to the client device (60, 61) directly or forward the response to another independent node (66) which can send the response back to the client device (60, 61).

Abstract: A method for real-time reconfiguration of a computer network using load information from the computer network. The method comprises receiving remote procedure call (RPC) information by a server in the computer network. The RPC information is analyzed. Based on the analysis, it is determined whether a reconfiguration is required. If reconfiguration is required, one or more objects are relocated until reconfiguration is completed.

Abstract: A method and system are provided for file system backup using multiple backup devices in parallel. The system stores files across the backup devices, by first copying small files of sizes below a calculated threshold size, and then splitting into segments those files that are larger then the calculated threshold size. For each file segment, the system affixes a unique segment header. At restore time, a restore program starts the restore from the first file segment and follows to the next file segment according to information specified in the file segment header.

Abstract: A system and method for load balancing between redundant elements in a system is provided. By using redundant elements overall performance of the system is improved without losing the capability to recover or continue operation upon failure of an element within the system. The solution is of particular use in network systems, networked storage systems as well as location independent file systems.
