Abstract: A NOF-based read control method, apparatus, and system belong to the field of networked storage. The method includes: receiving, by a NOF engine by using a communication link, a read request sent by a host; sending at least one read command to an NVMe hard disk based on the read request; and when congestion occurs on the communication link, generating a congestion flag corresponding to the communication link, and sending the congestion flag to the NVMe hard disk, where the congestion flag is used to instruct the NVMe hard disk to suspend processing of the read command corresponding to the communication link.

Abstract: An SR-IOV-supported storage resource access method is disclosed, the method includes: consolidating a storage medium as a unified storage resource, and dividing the unified storage resource into multiple storage sub-resources; allocating the storage sub-resources to at least one of a PF or a VF according to a preset allocation rule, and maintaining a resource allocation table including a mapping relationship between the storage sub-resources and at least one of PF or VF; receiving a host command sent by a virtual machine to a destination VF or by a virtual machine monitor to a destination PF; and searching the resource allocation table according to destination VF or destination PF, and performing, on a storage sub-resource corresponding to destination PF or destination VF and according to the mapping relationship between the storage sub-resources and the PF or the VF in the resource allocation table, an operation corresponding to the host command.
