Abstract: Systems and methods disclosed herein host bus adapter (HBA) drivers to detect when execution of input/output (I/O) commands in urgent-priority queues is being delayed due to processing of I/O commands in lower-priority queues in NVMe subsystems, automatically identify which the lower-priority queue that is causing the delay, and mitigate the delay by throttling and migrating the lower-priority queue to the control of a controller that applies an arbitration mechanism other than weighted round robin.

Abstract: Example implementations relate to virtual host bus adapter logins. A hypervisor may comprise a processing resource and a memory resource storing non-transitory machine-readable instructions to cause the processing resource to query a computing device to determine port identity information of a plurality of virtual host bus adapters (VHBAs) associated with a physical host bus adapter (HBA) of the computing device and uplink mappings for the plurality of VHBAs, determine a bandwidth allocation of each of the plurality of VHBAs, rank each of the plurality of VHBAs, and cause each of the plurality of VHBAs to login via the determined uplink mappings based on the rank of each of the plurality of VHBAs.
