摘要: A redundant array storage system that can be configured as a RAID 1, 3, 4, or 5 system, any combination of these configurations. The invention comprises configuration data structure for addressing and method configuring during an initialization process. set physical units which are accessible in terms block numbers. each one more logical units. Each unit is addressed channel number, starting offset number blocks to transferred. Once defined, volumes defined units, volume having depth characteristic. After the redundancy groups volumes. level specified group. may none, one, two. Logical by host CPU initial also specifies READ WRITE operation. transferred then translated into corresponding With present invention, it possible span across ("vertical partitioning"), comprise only portion such ("horizontal have definable characteristics.
