Abstract

The invention discloses a high-speed peripheral component interconnection switching controller which is used for realizing communication among a plurality of host controllers connected by a PCI Express protocol. The high-speed peripheral component interconnection switching controller comprises a configuration processor and a switching element, wherein the configuration processor is used for providing address ranges of a PCI Express switching controller for the host controllers and realizing access among the host controllers according to address information from the host controllers; and the switching element is used for realizing the communication between the configuration processor and the host controllers and among the host controllers. The invention ensures the high reliability of system operation and realizes continuous work without a pause.

Description

technical field [0001] The present invention relates to the field of communications, in particular to a high-speed peripheral component interconnect (Peripheral Component Interconnect Express, referred to as PCI Express) switch controller and an implementation method thereof. Background technique [0002] At present, PCI Express-based storage / server hardware generally adopts a dual-controller architecture. figure 1 It is a schematic diagram of a dual-controller architecture based on related technologies, such as figure 1 As shown, the whole system is composed of two relatively independent host controllers. The main architecture of each host controller consists of data input / output interface (Input / Output Interface), data input / output channel (Input / Output Channel), central processing unit (Central Processing Unit, referred to as CPU) and memory (Cache), wherein the number of data input and output interfaces, input and output channels, and memory is not limited, and there ca...
