Abstract: A method for temporarily storing data and a storage device is provided. The method for temporarily storing data is applied to the storage device, and the storage device includes a source agent and a target agent. The method includes: sending, by the source agent, a data obtaining request to the target agent; receiving, by the source agent, target data that is corresponding to the data obtaining request and is returned by the target agent; determining, by the source agent, whether a snooping request that is for the target data and sent by the target agent is received after the data obtaining request is sent and before the target data is received, where the snooping request indicates that the target agent is simultaneously processing an obtaining request from another source agent for the target data; and if the snooping request is received, discarding, by the source agent, the target data.

Abstract: A packet transmission method, packet transmission apparatus, and an interconnect interface are presented, where the method includes determining, by a sending node, whether an unrecoverable failure occurs in an active link, and if an unrecoverable failure occurs in the active link, selecting, from multiple communication links, at least one standby link except the active link to send a packet to a receiving node, so that the receiving node sends the packet to a receive end of the active link. In the method, for two nodes in an interconnect system that communicate with each other using multiple Links, when it is determined that an unrecoverable failure occurs in some of the Links, packets in retransmission buffers of transmit ends of the links in which the failure is unrecoverable are sent to a standby link.

Abstract: Embodiments of the present invention disclose a data processing method and apparatus. The method includes: first receiving an operation command, then searching, according to a memory address, a Cache memory in a Cache controller for data to be operated, and storing the operation command in a missed command buffer area in the Cache controller when the data to be operated is not found through searching in the Cache memory; then, storing data sent by an external memory in a data buffer area of the Cache controller after sending a read command to the external memory, and finally processing, according to a missed command, the data acquired from the external memory and the data carried in the missed command. The present invention applies to the field of computer systems.
