PCIE bandwidth automatic configuration method, server mainboard and server

Abstract

The invention discloses an automatic PCIE bandwidth configuration method, a server mainboard and a server. In this scheme, the method comprises the following steps that a BMC acquires identification information of a Riser card connected with a slot on a server mainboard, bandwidth configuration information of PCIE equipment inserted into a card slot of the Riser card and information of the card slot; the Riser card can transfer and distribute the bandwidth of the slot to each card slot on the Riser card; the BIOS chip determines the bandwidth of the card slot into which the PCIE equipment is inserted according to the identification information and the identification information of the card slot; after the bandwidth required by the PCIE equipment is determined according to the bandwidth configuration information, the bandwidth of the card slot inserted into the PCIE equipment is configured, so that the allocated bandwidth of the card slot conforms to the bandwidth of the PCIE equipment.According to the scheme, different BIOS chip versions do not need to be published for different models and packages, so the BIOS chip is convenient to maintain; the manual participation is not needed, and reliability and automation degree are high.

Description

technical field [0001] The invention relates to the technical field of bandwidth configuration, in particular to a PCIE bandwidth automatic configuration method, a server main board and a server. Background technique [0002] With the increasing integration of servers, manufacturers and customers attach great importance to the simplification and intelligence of human-computer interaction during server production. In order to provide customers with more flexible customization services, the server will configure multiple model packages for one server motherboard. Considering that the number of slots on the server motherboard is certain, in order to meet multiple PCIE (peripheral component interconnect express, high-speed serial In order to meet the requirement of connecting the computer expansion bus standard) equipment to the server main board, a riser card (that is, an adapter card) is usually arranged on the server main board. Use different types of riser cards to match di...

Problems solved by technology

[0003] Specifically, the BIOS (Basic Input Output System, Basic Input Output System) chip configures the bandwidth of the PCIE device plugged in based on the bandwidth configuration information, because the bandwidth configuration information corresponding to the PCIE device corresponding to different models and packages may also be different , in the prior art, the bandwidth configuration information is stored in the BIOS firmware in advance, if the bandwidth configuration information of the PCIE device is not stored in the BIOS firmware, the user needs to manually republish different BIOS versions to obtain the bandwidth configuration information of the PCIE device , it can be seen that the existing bandwidth configuration method makes the adaptability of the BIOS version poor
