  • Publication number: 20090013119
    Abstract: A storage controller receives an interrupt control directive from a host. The storage controller generates a first plurality of interrupts, in response to access requests received from the host for at least one storage device coupled to the storage controller, wherein the first plurality of interrupts indicates whether access to the at least one storage device is allowed to the host. The storage controller generates a second plurality of interrupts, wherein the second plurality of interrupts comprises unsolicited interrupts for the host that are different from the first plurality of interrupts. The storage controller controls how many of the first plurality of interrupts and how many of the second plurality interrupts to send to the host, based on the received interrupt control directive.

  • Publication number: 20080294826
    Abstract: A method is disclosed to control access to stored information. The method supplies a control unit in communication with a computing device and in communication with stored information. If the computing device requests access to that stored information, the method determines if access to the stored information is available. When access to the stored information becomes available, then the method reserves a communication pathway interconnecting the control unit and the requesting computing device, thereby disallowing the sending of non-MPLF unsolicited status via that reserved communication pathway, and provides a message to the computing device, using that reserved communication pathway, granting access to the stored information.

  • Publication number: 20080263083
    Abstract: A storage control unit detects a change in a configuration of a plurality of logical subsystems included in the storage control unit. The storage control unit sends a notification, wherein the notification indicates the change in the configuration of the plurality of logical subsystems. The storage control unit receives data transfer requests directed at available logical subsystems in the storage control unit, wherein the available logical subsystems are determined based on the configuration of the plurality of logical subsystems.

  • Publication number: 20080147869
    Abstract: An apparatus, system, and method are disclosed for an alternate lock facility connection path. A request module receives a connection request to establish redundant connection paths between a control unit and a host. A primary connection module establishes a first connection path between the control unit and the host through a first communication channel. An alternate connection module establishes a second connection path between the control unit and the host through a second communication channel. A detection module detects a failure of the first connection path. A redirection module redirects communication between the control unit and the host through the second connection path upon detection of a failure of the first connection path.

  • Patent number: 7340474
    Abstract: An apparatus, system, and method are disclosed for re-generating a data structure. A detection module detects corruption of a first data structure of a storage device. A removal module removes a first path from a host system to the first data structure without affecting communications through other paths between the host system and other data structures of the storage device. A path module establishes a second path from the host system to a second data structure of the storage device. A re-generation module generates the second data structure to replace the first data structure.

  • Publication number: 20050195521
    Abstract: A system, method, and apparatus for solving flow-induced track misregistration (TMR) problems in hard disk drives (HDD) are directed to breaking up large-scale eddies, and straightening air flows with honeycomb structures, woven wire screens, and guide vanes or holes. In addition, boundary layer manipulation techniques are applied to the airflow in the HDD, such as boundary layer suction with slots or holes, and wall damping techniques, such as an open honeycomb seal and Helmholtz resonators. These flow-conditioning solutions reduce the turbulence intensity throughout the HDD to reduce TMR. These solutions achieve these goals while minimizing increases in the running torque needed to overcome their inherent rotational drag.
