    摘要: A data storage managing system and method in which a HOST system obtains operation information of a storage device from a system connected to a network without the need for a specific device driver are disclosed. When disks shared between systems connected to the network are managed by a disk manager, monitoring and control information for the shared disks may be accessed by a file access command of the operating system on the HOST system. An operation information storage device is formed in a file format which can be accessed by a file access command of the operating system on the HOST system and the HOST system reads the operation information of the storage devices stored in the operation information file according to the file access command. The information to control the operation of the storage devices is written in the operation information file according to the file access command. The disk manager controls the operation of the storage devices according to the operation information of the operation information file.

    摘要: A transmission monitoring and controlling apparatus is provided between a first system and a second system. The transmission monitoring and controlling apparatus monitors information transmitted through a Fibre Channel. Then, a back controller analyzes the monitored information and stores the information in a controlling memory based on the analysis. For example, when the first system writes data on the second system, the back controller stores the data in the controlling memory. Therefore, even if a failure has occurred in the second system, the transmission monitoring and controlling apparatus is able to read the data from the controlling memory and send the data to the first system instead of to the second system.

    摘要: The present invention relates to an arrayed recording apparatus having spare devices for replacing faulty disk drives. Each of the SCSI controllers in the arrayed recording apparatus connects to a driver/receiver and further connects to spare disk drives. Each of the SCSI controllers accesses the spare disk drive by setting a receive/enable signal effective to the driver/receiver. Unused ID numbers are assigned to the spare disks. If a disk drive develops a fault, the RAID controller RC requests the SCSI controller to replace the faulty disk drive with the spare disk drive.It is possible to attain the function of the hot stand-by system without comprising a specific spare controller.

    摘要: The present invention relates to an arrayed recording apparatus with reduced writing time. Various devices are used to write data without redundant data and to update the redundant data more efficiently during idle time. In one embodiment, a temporary write track is provided for each cylinder. When data are read, updated and re-written, the data are re-written to the temporary write track. Since the re-writing does not require a full disk rotation, the writing occurs quickly. Data in the temporary write track are relocated into the disk during an idle state, without being synchronized. Additionally, corresponding blocks in data areas can be used for writing data rather than a specified temporary write track. In order to improve re-writing time, the rotation of the disk drives can be synchronized to avoid full rotations between reads and writes, or cache memories for each disk can be used. When data is accessed from a host computer in a first unit size and from the memory devices in a second unit size, a buffer and cache can be used to limit the written data to those portions of the second unit size which have been changed. Each of these devices reduces the total access time for writing to arrayed recording devices.

    摘要: A disk unit including a control unit for controlling the stop position of a positioning electric motor and positioning a magnetic head operatively linked with the positioning electric motor on a predetermined one of data tracks on a magnetic disk, and positioning error adjustment unit for supplying analog signals to the control unit, wherein the analog signals are related to the positioning error detected by the magnetic head. The control unit includes a control circuit for causing an exciting current which goes high during a time interval T1 and goes low during a time interval T2 during a period T to flow in a first exciting coil of the motor and for causing exciting current which goes low during the same time interval T1 and goes high during the same time interval T2 to flow in another exciting coil adjacent to the first coil, as a function of the magnitude of the aforementioned analog signal; the duration of the time intervals T1 and T2 with respect to the period T is adjusted by the control unit.

    摘要: In case of consecutive transmission of a large amount of data such as dynamic image data, a multi-media storage system of the invention generates and transmits data stored in a faulty disk drive when one of a plurality of disk drives being faulty caused by an internal calibration or an error of the disk drive and the faulty disk drive does not respond within a predetermined length of time set in a timeout table. The multi-media storage system cancels an access to the faulty disk drive, generates data to be read from the faulty disk drive based on data stored in the other disk drives of the plurality of disk drives and the redundant data and continues to transmit data.
