Abstract
The present disclosure generally relates to utilizing a port scheduler within a data storage device controller to schedule data transfers and determine which port should be utilized for each data packet transferred. The data storage device comprises a multi-port system on a host interface. The port scheduler can consider the following factors for example: link workload, idle time for each port, link power state, throughput for each port, speed of each link, priority of data transfer, and quality of service (QoS). Based upon an analysis of one or more of the factors, the port scheduler can transfer data on a port that is not associated with the data to ensure efficient multi-port usage.
