Problems solved by technology

[0003] At present, the solution to realize PCIe bandwidth identification and allocation generally comes from the static data of the riser card itself. These data are defined in advance and are not associated with the PCIe port. If the bandwidth requirement changes, the riser needs to be redefined. The original riser It cannot be reused, which causes a great waste of cost

Abstract

The invention provides an automatic PCIe bandwidth allocation method supporting servers, and a storage medium, belongs to the technical field of multi-host server equipment, and solves the problems ofincapability of automatically allocating equipment bandwidths, complex riser number and cost waste in an existing scheme. The method comprises the following steps: judging the type of a board card byreading a type signal; if the board card type is a backboard, generating bandwidth configuration information of a port corresponding to the backboard; if the type of the board card is riser, readinga host information signal to judge whether the current state is a multi-host working state or not, and correspondingly generating bandwidth configuration information of a port corresponding to the riser; and performing bandwidth allocation on each board card according to the bandwidth configuration information.

Description

technical field [0001] The present invention relates to the technical field of multi-host server equipment, in particular to a PCIe bandwidth allocation method, device and storage medium supporting multi-host servers. Background technique [0002] As the application scope and scenarios of servers become increasingly complex, the configuration of servers also increases. At the same time, as Intel continues to upgrade, the PCIe resources of the CPU are becoming more and more abundant. In order to adapt to increasingly complex configurations, these rich PCIe resources are often more and more flexible at the system design level. Reserving high-speed connectors on the motherboard to meet different configuration requirements is currently the mainstream practice in the industry. During the server startup phase, the BIOS needs to identify the peripherals of the server and allocate PCIe bandwidth according to the peripherals. [0003] At present, the solution to realize PCIe bandwid...
