Hot swap processing system and method

Abstract

The invention provides a hot-plug processing system and a hot-plug processing method. The system comprises a plurality of pieces of PCIE equipment, at least one PCIE exchange chip, a master control board and a management board, wherein the PCIE exchange chip comprises a plurality of PCIE ports which are used for connecting the pieces of PCIE equipment; each PCIE port is distributed with a fixed PCIE port resource; each PCIE port resource corresponds to an address of an IPMI bus; the master control board distributes the fixed PCIE port resources to the pieces of PCIE equipment which are connected with the corresponding PCIE ports or recycles the fixed PCIE port resources; the management board detects the state of each piece of PCIE equipment connected with the corresponding PCIE port through the address of the IPMI bus, transmits indicating information to the master control board, and indicates the master control board to distribute the fixed PCIE port resources to the pieces of PCIE equipment connected with the PCIE ports or recycle the fixed PCIE port resources. According to the hot-plug processing system and the hot-plug processing method, the plugging and unplugging sequence of the PCIE equipment does not affect the distribution of resources.

Description

technical field [0001] The invention relates to the field of computer application technology, in particular to a hot swap processing system and method. Background technique [0002] The ATCA bus is composed of a series of specifications, including the core specification PICMG3.0 that defines the structure, power supply, heat dissipation, interconnection and system management, and 5 auxiliary specifications that define the point-to-point interconnection protocol, including: Ethernet and optical fiber transmission; InfiniBand transmission; Star transmission; PCI-Express transmission; and RapidIO transmission. [0003] ATCA adopts the industry-standard IPMI bus (Intelligent Platform Management Interfaee, Intelligent Platform Management Interface) as the basis of management functions, and provides a reliable management mechanism at the chassis level. [0004] PCIE is a local bus, and most processors currently include a PCIE controller to connect external devices for data transm...

AI Technical Summary

Problems solved by technology

[0009] ATCA 3.4 supports all PCIE hot-swap schemes, and the Linux operating system also implements the PCIE hot-swap scheme. When the hot-swap driver is normal, the PCIE address space is allocated to the newly inserted blade, and the address of the unplugged blade is recycled. , but the PCIE address space in this solution is dynamically allocated, that is, depending on the order of blade insertion and removal, the PCIE address space of a certain slot cannot be fixed, which brings a lot of inconvenience to hardware design and application design
