Abstract

The embodiment of the invention discloses a data sharing method and a communications system and a device thereof, for realizing the data sharing of a plurality of host computers to reduce the cost, The embodiment method of the invention includes: receiving the data processing request transmitted by at least two host computers through the PCIE channel by the peripheral equipment expansion interface PCIE exchanger; transmitting the received data processing request to the memory system, indicating the memory system to obtain the corresponding data according to the data processing request, and indicating the memory system to perform the corresponding process on the obtained data, wherein the memory system and at least two host computers perform the address space isolation through the non-transparent port bridge NTP in the PCIE exchanger. The embodiment of the invention also provides a communication system and a PCIE exchanger. The embodiment of the invention realizes the data sharing between a plurality of host computers.

Description

technical field [0001] The invention relates to the communication field, in particular to a data sharing method, a communication system and related equipment. Background technique [0002] With the wide application of Internet (Internet) and intranet (Intranet) technology, the amount of data information is growing rapidly. In the past, each host had its own storage device, and the information was isolated from each other, forming an information island. With the continuous development of business needs, the demand for information is increasing day by day, especially the application of large data warehouses, large design systems, graphics processing systems, online transaction processing systems, broadband multimedia systems, telecommunications integrated business systems, securities trading systems, banking systems The emergence of computer systems urgently needs a computer system that stores large-capacity information. The appearance of Storage Area Network (SAN, StorageAr...
