Abstract: A method and apparatus for identifying each of the members of a set of physical mass storage devices acting as one logical mass storage device are provided. Each physical mass storage device is assigned a membership signature identifying it as a valid member of the set. Whenever a member of a set undergoes a change in membership status, the membership signatures of all other devices in the set are changed, so that the member with the changed membership state no longer has a valid signature. When the member is reinstalled, it can be given a new valid signature after it is updated or regenerated.

Abstract: 2077447 9114229 PCTABS00007 A network-type (10) data processing system is provided. The system can support multiple simultaneous exchanges of data, and includes multi-port storage devices (100-104) in which all ports can be active at all times. On initialization of the system, each storage device can announce itself through all of its ports simultaneously through at least 2 paths.

Abstract: A mass storage apparatus, made up of a plurality of physical storage devices, which is capable of providing both high bandwidth and high operation rate, as necessary, along with high reliability, is provided. The device set is divided into one or more redundancy groups. Each redundancy group is in turn divided into one or more data groups, each of which may span only a small number of the drives in the redundancy group, providing a high request rate, or which may span a large number of drives, providing high bandwidth.

Abstract: A circuit for decoding a high speed Manchester encoded digital communication signal is provided. The circuit includes a pair of latch circuits which are used to detect clock edges in the encoded signal for providing respectively set and reset pulses to a third latch circuit, an output of which comprises the decoded data of the Manchester code signal. Additional logic is provided to extract a clock signal from the Manchester code signal.

Abstract: A mass memory system for digital computers is disclosed. The system has a plurality of disk drives coupled to a plurality of small buffers. An Error Correction Controller is coupled to a plurality of X-bar switches, the X-bar switches being connected between each disk drive and its buffers. Data is read from and written to the disk drives in parallel and error correction is also performed in parallel. The X-bar switches are used to couple and decouple functional and nonfunctional disk drives to the system as necessary. Likewise, the buffers can be disconnected from the system should they fail. The parallel architecture, combined with a Reed-Solomon error detection and correction scheme and X-bar switches allows the system to tolerate and correct any two failed drives, allowing for high fault-tolerance operation.
