AI Technical Summary
In existing technologies, the fixed Board ID on PCIe adapter cards makes it impossible to flexibly adjust the bandwidth allocation of PCIe slots, which cannot adapt to the diverse needs of multiple host PCIe cards, resulting in poor adaptive bandwidth allocation capabilities.
The bandwidth allocation information of the PCIe card is obtained through the Baseboard Management Controller (BMC), the PCIe card type is determined, and a target board identification code is generated based on this information and recorded in the BIOS configuration file. The bandwidth allocation is dynamically adjusted to support flexible bandwidth allocation for multiple host PCIe cards.
Without replacing the PCIe adapter card, adaptive bandwidth allocation for multiple host PCIe cards is achieved, improving the flexibility and adaptability of bandwidth allocation for PCIe card slots.
