Abstract

The invention discloses a PCIE (Peripheral Component Interconnect Express) expansion device, which comprises a serial system interface connector connected to a processor; one or more switching chips,each switching chip having a plurality of stations, one switching chip being directly connected to the serial system interface connector by one or two stations thereof, the other switching chips beingindirectly connected to the serial system interface connector by one or two stations thereof via the directly connected switching chip; and a plurality of PCIE slots, wherein each PCIE slot is directly connected to one station of one switching chip. According to the technical scheme provided by the invention, different PCIE devices or different types of PCIE devices can be expanded and hung, andthe expandability requirement of a user is met.

Description

technical field [0001] The present invention relates to the computer field, and more specifically, relates to a PCIE expansion device. Background technique [0002] The traditional server model generally only focuses on basic attributes, such as computing speed, machine stability, etc., and does not pay attention to IO expansion functions. Now due to the diversification and rapid increase in the number of PCIE devices, users have more requirements for connecting PCIE. In addition, the rapid rise of artificial intelligence business puts forward a stronger demand for input and output interface expansion (IO expansion) (connecting GPU), but the traditional server model cannot meet the demand. [0003] There is no effective solution to the problem of insufficient PCIE resources of traditional servers in the prior art. Contents of the invention [0004] In view of this, the purpose of the embodiments of the present invention is to provide a PCIE expansion device, which can ex...
