Abstract: The present invention provides a storage controller and a using method therefor. The method comprises: processors send a storage instruction; a processor controller receives the storage instructions sent by the processors, and sends the storage instructions to an exchanger; the exchanger sends the storage instructions to a hard disk controller one by one; and the hard disk controller sends the storage instructions to a hard disk according to storage address spaces indicated in the storage instructions, the indicated address spaces being address spaces allocated to the processors sending the storage instructions. By using the technical scheme of the present invention, multiplexing of the same physical storage space for the storage instructions of multiple processors can be ensured in a time-sharing mechanism, and accordingly, a purpose that the multiple processors share the same physical storage space by means of hardware is achieved.

Abstract: Provided is a cloud server system, the system comprising a plurality of multi-root input/output virtualized PCIE switches (MR-IOV Switches) that are interconnected each other. The cloud server system based on the MR-IOV PCIE Switch in the present invention can well meet the design requirements of the cloud servers very well, with a high performance-to-consumption ratio, strong overall service capability, low cost, low power consumption and high energy efficiency. I/O virtualization is realized architecture, thus maximally ensuring the performance of the server.

Abstract: A position mechanism includes a base and a telescopable member. The base defines a first receiving cavity. The telescopable member includes a base portion and a protruding portion protruding from a top of the base portion. A step is formed between the base portion and the protruding portion. The base portion is received in the first receiving cavity and capable of sliding in the first receiving cavity.

Abstract: A power plug having backup fuse tube, its major objective is that, when a fuse tube is damaged, a replaceable backup fuse tube can be obtained readily and promptly. The power plug has a backup fuse tube with pins and a casing, lead-out wires. A cavity is provided in the casing. The cavity is covered with a matching backup fuse tube holder. On a backside of the backup fuse tube holder a retainer is provided, and a backup fuse tube is placed in the retainer.
