    摘要: The peripheral bus connector for improved aggregation of resources of a device on the peripheral bus includes a plurality of aggregation pins, in addition to the pins according to the peripheral bus standard. Signals from a controller on an extended peripheral bus adapter sends and receives signals in addition to standard signals of the peripheral bus through the aggregation pins. The aggregated device is hidden from third parties, and its existence is known only to the controller on the extended peripheral bus adapter. In this manner, resources are aggregated across a peripheral bus without needing the addition of another controller and without the need to redefine standard peripheral bus signals. In addition, standard peripheral bus adapters may still be used in the connector if resource aggregation is not desired.

    摘要: Arrangements for physically partitioning a bus having a well defined architecture as a physical entity, wherein the partitioning is logically transparent to a computer and devices which communicate through the bus and serves to avoid problems potentially arising because of the scope of actions permitted by the architecture. A typical bus architecture to which present arrangements have relevance is that associated with SCSI (Small Computer System Interface) buses. The potential problems allowed to occur architecturally involve: (a) exposures of data security/integrity; (b) excessive signal degradation due to use of signal rates which although allowed by the architecture are inappropriate for a particular bus loading environment also allowed by the architecture; (c) restrictions preventing parallel transfer of data between the computer and multiple storage devices; (d) restrictions unduly limiting the number of devices attachable to one logical bus path (one input-output channel of the computer). The disclosed arrangement partitions the bus into two or more physical entities which to the computer appears as one logical entity.

    摘要: A plug-in feature board for a computer system has special circuitry to permit the board to customize itself to the particular slot into which it is inserted. Computers of the type intended for individual use or use in small networks typically provide insertion slots including connectors to permit feature boards to be added and connected to a bus of the computer for adding new function or capacity. As the computing power of such systems has increased there have been increases in the size of portions of the connecting bus to permit improvements in data transfer performance. In a given computer system there are often two or more bus connector configurations presented in respective slots. By so converting electrical states at selected connector positions as to provide signal information for determining bus configuration for the slot, special logic provided on the board is enabled to determine the characteristics of the slot in which the board is placed and customizes the board to respond or limit response in accordance with the requirements for that configuration. By so adapting to the slot the board achieves enhanced applicability and avoids certain system disabling malfunctions which can occur when a board is plugged into a slot for which it is not configured.

    摘要: When transferring data to a cache memory from an attachment data storage device, additional unrequested information can be transferred at the same time if it is likely that this additional data will soon be requested. The average quantity of data transferred to the cache memory in each operation can be automatically and continually varied in order to maximize the performance advantage provided by the cache memory. When a record of data is requested by the host processor, data is transferred to the cache memory from an attachment data storage device in increments of fixed-length data blocks each containing a sequence of data records, with the number of transferred blocks being determined by the position of a requested data record in its respective data block, and the average number of blocks transferred in any one operation being varied by adjusting threshold position values at which second or third data blocks are transferred.

    摘要: A disk drive receives a request to write at least one block of a first block size, wherein the disk drive is configured to store blocks of a second block size that is larger in size than the first block size. The disk drive stores a plurality of emulated blocks of the first block size in each block of the second block size. The disk drive generates a read error, in response to reading a selected block of the second block size in which the at least block of the first block size is to be written via an emulation. The disk drive performs a destructive write of selected emulated blocks of the first block size that caused the read error to be generated. The disk drive writes the at least one block of the first block size in the selected block of the second block size.

    摘要: A storage subsystem such as an array of disk drives, method of managing disk drives in the storage subsystem and program product therefor. The storage subsystem may be a redundant array of independent disks (RAID) and the individual disks drives may be Self-Monitoring, Analysis and Reporting Technology (SMART) capable drives. When one of the drives gives an indication of an impending failure, a disk image of the failing disk is built on an available spare disk. Once the image is complete, the failing disk may be replaced without down time for rebuilding a failed disk.
