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： For the high-speed data access machine, data is distributed in a plurality of hard disk drives coupled to slave processors to achieve ever-higher data reliability and maintenance. One master processor is provided with a plurality of slave processors, each of which is coupled to two hard disk drives containing the same data. A synchronous signal permits two hard disk drives to operate in synchronous rotation in half-a-turn phase difference from each other. The hard disk controller writes the same data in both hard disk drives but reads data from whichever hard disk drive requires less access time to obtain the data. A plurality of hard disk drives holding exactly the same data improves data reliability. Also, by rotating a plurality of hard disk drives in different phase, the rotational delay in data access is cut by half.

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.
摘要翻译：本发明涉及一种缩短写入时间的阵列式记录装置。各种设备用于写入无冗余数据的数据，并在空闲时间内更有效地更新冗余数据。在一个实施例中，为每个气缸提供临时写入磁道。当读取，更新和重新写入数据时，将数据重新写入临时写入磁道。由于重写不需要完全磁盘旋转，因此写入速度很快。临时写入磁道中的数据在空闲状态下被重定位到磁盘中，而不进行同步。此外，数据区域中的相应块可用于写入数据而不是指定的临时写入磁道。为了提高重写时间，可以同步磁盘驱动器的旋转以避免读写之间的完全旋转，或者可以使用每个磁盘的高速缓冲存储器。当以第一单元大小从主计算机访问数据并且以第二单元大小从存储设备访问数据时，可以使用缓冲器和高速缓存来将写入的数据限制为已经被改变的第二单元大小的那些部分。这些设备中的每一个减少了写入阵列记录设备的总访问时间。

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.
