    摘要: A method, system, and computer program product for facilitating power instability in a central electronics complex (CEC) of data storage computing environment in advance of a potential power failure is provided. Upon receipt of a first early power off warning (EPOW) signal indicating power instability, a first priority of execution of a first data storage task to be performed pursuant to a new data storage request is decreased, while a second priority of execution of a second data storage task to destage data in nonvolatile storage (NVS) to disk is increased. Upon receipt of a second EPOW signal indicating power failure, a system shutdown procedure is executed.

    摘要: For managing a storage server having improving overall system performance, a first input/output (I/O) request is received. A first priority level is dynamically assigned to the first I/O request, the first I/O request associated with a performance level for an application residing on a host in communication with the storage server. A second I/O request of a second priority level is throttled to allow at least a portion of a predetermined amount of resources previously designated for performing the second I/O request to be re-allocated to performing the first I/O request. The second priority level is different than the first priority level.

    摘要: A connector assembly includes a female connector and a mal connector. The female connector includes a first main body and a number of slots defined in the first main body, and each slot receives a conductive terminal therein. First and second row conductive terminals are arranged along an opposite direction. A number of cables are attached to the first main body and electrically connected to the conductive terminals. A male connector includes a second main body and a number of conductive pins extend through the second main body. Third row conductive pins are corresponding to the first row conductive terminals. Fourth row conductive pins are corresponding to the second row conductive terminals. The connector assembly can transmit signals normally whatever the male connector is plugged to the female connector.
