Abstract

A method and an information handling system (IHS) selectively configures a peripheral component interconnect express (PCIe) device with single or multiple root ability to service various compute node requests. A multi-root aware (MRA) module that manages an MRA switch receives requests for powering on PCIe adapters in respective chassis slot locations. If slot locations of respective PCIe adapters are designated as single root and unshared PCIe device slots, the MRA module provides power to the PCIe adapters and configures the PCIe adapter with single root ability. If slot locations of respective PCIe adapters are designated as multi-root and shared PCIe device slots, and corresponding PCIe adapters are single root input/output virtualization (SR-IOV) aware, the MRA module provides power to corresponding PCIe adapters, and configures, using the appropriate device drivers, the PCIe adapters with multi-root ability. The MRA module connects compute nodes via the MRA switch to requested PCIe device functions.
