Abstract: A method, a network card, and a hard disk card for accessing a shut-down hard disk are provided. The method includes: after receiving a shutdown instruction sent by a central processing unit (CPU), a coprocessor is powered up and takes over a network card and a secondary hard disk controller; the coprocessor creates an operation instruction according to a data operation request received by the network card; and the coprocessor sends the operation instruction to the secondary hard disk controller, so that the secondary hard disk controller performs a read/write operation on a hard disk. When a computer is shut down, a coprocessor takes over management work of a network and hard disk reading and writing, and a secondary hard disk controller takes responsibility for controlling a read/write operation on a hard disk. Thus, energy is minimized when accessing of a shut-down hard disk is implemented.

Abstract: An interconnection system, an apparatus, and a data transmission method. In the interconnection system, to-be-transmitted data is converted into a data packet in an optical signal form for transmission, and a control packet corresponding to the data packet is transmitted in an electrical signal form and includes routing information of the data packet. When the control packet passes through a switching node, the switching node directly determines, according to the routing information in the control packet, a neighboring node that serves as a next hop, and opens, in the switching node, an optical path used to transmit the data packet. Because no optical-to-electrical or electrical-to-optical conversion needs to be performed on the control packet and the data packet during an entire transmission procedure, problems of an extra delay and power consumption caused by electrical-optical-electrical conversion can be reduced, thereby improving data transmission efficiency.
