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.

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.

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.

Abstract: A recyclable electric junction box applicable to automotive vehicles, of the type comprising at least one casing housing a series of circuits inside materialized in one or more printed circuit boards with a series of electroconducting tracks on at least one of its sides, and with a series of components assembled on said plates, welded on said tracks and responsible for carrying out at least one power stage and one signal stage.

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.
