  • Patent number: 6471308
    Abstract: The frameless, stackable cabinet system for use with rack mounted electronic equipment comprises stackable wall members that mechanically interconnect without the need for tools to assemble the cabinet. A base unit and cover unit provide the interlocking top and bottom members of the cabinet. The stackable wall members come in various heights and can be interlocked together and to both the base unit and cover unit to configure a cabinet of desired height. Each stackable wall member therefore not only provides a mounting site for a rack mounted piece of electronic equipment, but also serves to provide the wiring channels through openings formed in the stackable wall members. The cabinet system can be transported in a disassembled form to reduce shipping costs and can be simply assembled on site via the interlocking interconnection of the stackable wall members. The resultant cabinet can be reconfigured without a significant effort and the certification of the resultant cabinet configuration can be simplified.

  • Patent number: 6351792
    Abstract: The invention provides for remote copying, between peer storage systems, with data extent granularity. A compressed data image is read from a first location of a primary storage volume. Metadata, and then the compressed data image, are transferred to a secondary storage volume. The metadata specifies a first location within the primary storage volume and a second location within the secondary storage volume. The compressed track is then stored into a second location of the secondary volume. A host connected to the primary control unit specifies data extents within the primary and secondary volumes. The data extents specify the first and second locations, and more preferably define cylinder information, track information, and start and end addresses. An “Establish Pair” command can be used to specify the data extents. A seed value can be used with the metadata to identify the data image during subsequent decompression of the data image in the secondary storage volume.

  • Patent number: 6349150
    Abstract: Data compression logic of the invention compresses data from a host to a connected cache memory for storage within a storage device. A compressor within the logic implements a compression algorithm on the data; and a plurality of Chunk RAMs store compressed and uncompressed data chunks from the compressor. Predictive digital logic assesses memory usage within the RAMS while uncompressed and compressed chunks are stored within the RAMs. The predictive digital logic selects one RAM to drain its data into the cache memory based upon the compression efficiency of the compressed data as compared to the uncompressed data and prior to the complete loading of the chunks within the RAMs, resulting in reduced latency in writing compressed data to the connected cache memory. The predictive digital logic can include calculation logic for dynamically calculating compression efficiency, used in selecting which RAM to drain.

  • Patent number: 6347139
    Abstract: The system for automatically routing calls to call center agents in an agent surplus condition provides the call center administrator with an automatic agent assignment paradigm which functions to automatically increase the efficiency of assigning multiple skill agents to contacts. The presence of an agent surplus condition provides the present system with a plurality of choices in the assignment of the agent to process a presently received contact. Since the agents who staff the call center include multiple skill agents, the system must make a determination of not only which of the available agents is the best equipped to handle the present contact, but also how that assignment statistically effects the efficiency of successive assignments of agents to contacts next received, based upon the past performance of the agents and the call center.

  • Patent number: 6347389
    Abstract: The pipelined high speed Reed-Solomon error/erasure decoder processes multiple code words in a pipelined fashion. The pipelined high speed Reed-Solomon error/erasure decoder is designed to process Reed-Solomon encoded words that have been corrupted in a digital system by processing errors as well as erasures through a simple iterative modified syndrome process. The iterative nature of this method provides for limited computational effort at each step of the pipeline. This allows the pipelined high speed Reed-Solomon error/erasure decoder to easily handle full or shortened Reed-Solomon codes, as well as parallel processing to achieve higher data rates. The iterative modified syndrome process is one of the pipelined steps. It relieves the erasure pre-shifting burden from the Berlekamp/Massey synthesis process, which reduces the number of cycles required at that stage of processing. The decoder proceeds classically with a Chien Search for any remaining error locations.

  • Patent number: 6311251
    Abstract: The intelligent data storage manager functions to optimize the data storage utilization in a RAID data storage subsystem that is equipped with a heterogeneous mix of data storage elements. This is accomplished by using preference groups and biasing the writing of stripes of data in the redundancy groups of the RAID system to the disk drive or a set of disk drives in the preference group that have the greatest available data storage capacity. This ensures that the data storage capacity of the the disk drive with the largest available capacity is utilized to the maximum capacity. A preference group comprises a group of disk drives that is larger than the stripe size that is used to store data in a RAID format. The data storage manager does not write data across all of the disk drives in the preference group at a time, but rotates the collection of disk drives that are used to write a stripe of data.
