Abstract: A circuit board assembly is applied to the field of electronic communications technologies to resolve a prior-art heat dissipation problem of a circuit board. The circuit board assembly combines, on a second circuit board, low-speed signals transmitted between a plurality of I/O modules and an IC chip, and then transmits the combined low-speed signals to the IC chip by using a low-speed cable. A low-speed signal sent by the IC chip to the plurality of I/O modules is extended to a plurality of low-speed signals on the second circuit board, and then the plurality of low-speed signals are separately sent to the plurality of I/O modules. This may be applied to a scenario in which a relatively large quantity of electronic components need to be disposed on a circuit board.

Abstract: Distributed storage system and method for transmitting storage-related messages between host computers in a distributed storage system uses a handshake operation of a first-type communication connection between a source data transport daemon of a source host computer and a target data transport daemon of a target host computer to derive a symmetric key at each of the source and target data transport daemons. The two symmetric keys are sent to a source data transport manager of the source host computer and to a target data transport manager of the target host computer. The source and target data transport managers then use the same symmetric keys to encrypt and decrypt storage-related messages that are transmitted from the source data transport manager to the target data transport manager through multiple second-type communication connections between the source and target data transport managers.
