    摘要: The present invention describes lossless data compression/decompression methods and systems. A random access memory (RAM) operates as a static dictionary and includes commonly used strings/symbols/phrases/words. An input buffer operates as a dynamic dictionary and includes input strings/phrases/symbols/words. A set-associative cache memory operates as a hash table, and includes pointers pointing to the commonly used strings/symbols/phrases/words in the static dictionary and/or pointing to one or more of the input strings/phrases/symbols/words in the dynamic dictionary. Alternatively, the set-associative cache memory combines the dynamic dictionary, the static dictionary and the hash table. When encountering a symbol/phrase/string/word in the static or dynamic dictionary in an input stream, a compressor logic or module places a pointer pointing to the symbol/phrase/string/word at a current location on the output stream. The hash table may include phrases/symbols/strings/words and/or pointers pointing to phrases/symbols/strings/words.

    摘要: The present invention reduces the number of writes to a main memory to increase useful life of the main memory. To reduce the number of writes to the main memory, data to be written is written to a cache line in a lowest-level cache memory and in a higher-level cache memory(s). If the cache line in the lowest-level cache memory is full, the number of used cache lines in the lowest-level cache reaches a threshold, or there is a need for an empty entry in the lowest-level cache, a processor or a hardware unit compresses content of the cache line and stores the compressed content in the main memory. The present invention also provides LZB algorithm allowing decompression of data from an arbitrary location in compressed data stream with a bound on the number of characters which needs to be processed before a character or string of interest is processed.

    摘要: A method is provided for manipulating a compressed translation table in a memory expansion technology system. The method comprises swapping contents of an output buffer with contents of a compression buffer, disabling compression for compression translation table entries corresponding to the content swapped to the compression buffer, and packaging entries of a compression translation table corresponding to the contents swapped to the compression buffer, wherein packaged compression translation table entries are accessible to a computer system for addressing the contents swapped to the compression buffer.

    摘要: Two methods (native and clone) are used for installing software, such as an operating system, on client system(s) booting from shared storage. The native installation method configures an interconnection network to create an exclusive communication zone between the client system and the shared storage system and installs the operating system on the client system using the exclusive communication zone. After the software is installed, the method terminates the exclusive communication zone. The clone installation method utilizes a point-in-time copy feature of the shared storage system to clone an operating system drive instantaneously. After the drive is cloned, it is logically attached to a new client and the operating system is customized for that client.

    摘要: A set of disks in a plurality of disk arrays are configured to have one or more spare partitions. Upon detecting a faulty disk in a faulty array, the method involves the steps of: (a) migrating data in the faulty array containing the faulty disk to one or more spare partitions; (b) reconfiguring the faulty array to form a new array without the faulty disk; (c) migrating data from one or more spare partitions in the set of disks to the reconfigured new array; (d) monitoring to identify when overall spare capacity falls below a predetermined threshold; and when the predetermined threshold is exceeded, scheduling a service visit for replacement of the failed disks.

    摘要: A computer implemented method, apparatus, and computer usable program product for managing redundant array of independent drives. In response to a failure of a hard disk in a first RAID array, the process calculates an amount of free capacity available across a set of remaining hard disks in the first RAID array. The set of remaining hard disks comprises every hard disk associated with the first RAID array except the failed disk. In response to a determination that the amount of free capacity is sufficient to re-create the first RAID array at a same RAID level, the process reconstructs the first RAID array using an amount of space in the set of remaining drives utilized by the first RAID array and the free capacity to form a new RAID array without utilizing a spare hard disk.
