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.
