An apparatus comprising a logically contiguous group of at least two drives, a loop and a compression/decompression circuit. Each of the drives comprises (i) a first region configured to store compressed data of a previous drive and (ii) a second region configured to store uncompressed data of the drive. The loop may be connected to the next drive in the logically contiguous group. The compression/decompression circuit may be configured to compress and decompress the data stored on each of the drives.

Method to establish high level of redundancy, fault tolerance and performance in a raid system without using parity and mirroring

An apparatus comprising a logically contiguous group of at least three drives, a first loop, a second loop, and a compression/decompression circuit. Each of the drives comprises (i) a first region configured to store compressed data of a previous drive, (ii) a second region configured to store uncompressed data of the drive, (iii) a third region configured to store compressed data of a next drive. The first loop may be connected to the next drive in the logically contiguous group. The second loop may be connected to the previous drive of the logically contiguous group. The compression/decompression circuit may be configured to compress and decompress the data stored on each of the drives.

Method to establish redundancy and fault tolerance better than RAID level 6 without using parity

A method for configuring a storage array, comprising the steps of (A) checking a syntax of an input file, (B) generating an error if a particular syntax is not met, (C) determining whether a physical hardware configuration matches a desired set of design parameters, (D) generating a script file containing a plurality of symbol commands, (E) sending the script file containing the symbol commands to the storage array and (F) verifying whether the physical hardware configuration is valid.
