Scalable data storage architecture and methods of eliminating I/O traffic bottlenecks

An apparatus and method implemented in hardware and embedded software that improves performance, scalability, reliability, and affordability of Storage Area Network (SAN) systems or subsystems. The apparatus contains host computers (application servers, file servers, computer cluster systems, or desktop workstations), SAN controllers connected via a bus or network interconnect, disk drive enclosures with controllers connected via network interconnect, and physical drive pool or cluster of other data storage devices that share I/O traffic, providing distributed high performance centrally managed storage solution. This approach eliminates I/O bottlenecks and improves scalability and performance over the existing SAN architectures. Although this architecture is network interconnect (transport) neutral, additional improvements and cost savings could be made by utilizing existing, of the shelf, low latency and high speed hardware such as Advanced Switching (AS) or Myrinet networks as a transport for data, Small Computer System Interface (SCSI) and other commands and messages. Using AS or Myrinet network as a replacement for Fiber Channel (FC) would significantly reduce the cost of such SAN systems and at the same time boost performance (higher data transfer rates and lower latencies). This invention is about defining hardware and software architectural solution that is specifically designed to eliminate I/O traffic bottlenecks, improve scalability, and reduce the overall cost of today's SAN systems or subsystems. This innovative solution, in addition to it's performance superiority compared to the existing solutions, should also provide 100% compatibility with the all existing Operating Systems (OS), File Systems (FS), and existing applications.

Fast data decoder that operates with reduced output buffer bounds checking

Described is an improved decoder that reduces the number of bounds checks needed for typical compressed data by first guaranteeing that there is sufficient room to decode small symbol substrings and literal symbols, whereby bounds checking need not be performed on each symbol. Because literal symbols and small substrings of symbols form the majority of compressed data, the reduced checking significantly speeds up decoding on average. In one implementation, a fast LZ77 decoder that operates without bounds checking is used in a first phase until the end of the output buffer is neared at which time a second phase standard decoder, which performs bounds checks on each to ensure that the buffer does not overflow, is used. Normally the standard decoder decompresses only a small amount of data relative to the amount of data decompressed with the fast decoder, greatly improving decompression speed while not compromising safety.

Layout structure of semiconductor memory device having iosa

Embodiments of the invention provide a layout for a semiconductor memory device that splits each memory bank into two blocks. Embodiments of the invention dispose input / output sense amplifiers between the two memory blocks to achieve relatively short global input / output lines to all areas of the memory bank. Shorter global input / output lines have less loading and therefore enable higher-speed data transfer rates. Some embodiments of the invention include column selection line repeaters between the two memory blocks. The column selection line repeaters reduce loading in the column selection lines, and increase column selection speed. Embodiments of the invention include both input / output sense amplifiers and column selection line repeaters disposed between the two memory blocks to increase data transfer rates on the global input / output lines and also increase column selection speed.
