  • Patent number: 6990603
    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.

  • Publication number: 20030158942
    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.

  • Publication number: 20030126247
    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.

  • Publication number: 20030095501
    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.
