Abstract: A computer system and a storage access apparatus are provided. The storage access apparatus is configured to: configure at least one virtual function VF by using a physical function PF of an single-root I/O virtualization (SR-IOV) function, and configure a VM-VF association relationship, so that a direct access path is established between a VM and a VF that are associated; and obtain, by using a network interface, data block resources provided by at least one network storage device that is connected to the storage access apparatus, form a plurality of virtual volumes by using the obtained data block resources, and configure a VF-virtual volume association relationship. Therefore, by using a storage access method supported by the storage access apparatus, a storage access path and latency can be shortened, and occupation of CPU resources in a compute node can be reduced.

Abstract: Embodiments provide a resource management technology that may be applied to a host, where the host includes a CPU, an endpoint connected to the CPU, and an I/O device connected to the endpoint. A method includes: allocating, by the CPU, a target endpoint to a target process, where a virtual device is disposed on the target endpoint; obtaining, by the target endpoint, a performance specification of the target process, and adjusting a performance parameter of the virtual device according to the performance specification, where the adjusted virtual device satisfies a total requirement of performance specifications of all processes that use the target endpoint; and when the target process needs to access a resource, obtaining, from the I/O device, a resource that satisfies the performance specification of the target process, and providing the obtained resource to the target process for use.
