Abstract: Examples include distribution of I/O Q-connections of an NVMe™ subsystem among hosts that are to communicate with the NVMe™ subsystem in an NVMe™ zone of a system. Some examples receive information including a number of I/O Q-connections available at the NVMe™ subsystem, register the number of available I/O Q-connections of the NVMe™ subsystem with an NVMe™ fabric controller, determine a number of I/O Q-connections of the NVMe™ subsystem allowed to be used by each host and send to, each host, a first notification including the number of allowed I/O Q-connections of the NVMe™ subsystem to be used by the host.

Abstract: In some examples, a management system receives, from a first storage system, first port information of ports in the first storage system, and receives, from a second storage system, second port information of ports in a second storage system. The management system merges the first port information from the first storage system and the second port information from the second storage system into merged port information. The management system receives, from the first storage system, a request for port information of ports in the second storage system, and sends, to the first storage system, the second port information for use in path selection from hosts to the first and second storage systems.

Abstract: Examples include determination of non-TDP zones in a storage area network. Some examples use a member zone list request to request identification of each zone of which a target port of a target device is a member, identify each TDP zone among identified zones of which a target port is a member and determine whether the identified zones include one or more non-TDP zones.

Abstract: Examples relate to managing distribution of a total number of I/O queue pairs of an NVMe target among a plurality of NVM subsystems of the NVMe target and a plurality of hosts connected to the NVMe target. A target controller of the NVMe target defines a number of I/O queue pairs for a dedicated pool and a number of I/O queue pairs for a reserved pool based on the total number of I/O queue pairs. The target controller distributes a number of I/O queue pairs to each of the hosts from the number of I/O queue pairs of the dedicated pool and utilizes the number of I/O queue pairs of the reserved pool to balance out the number of I/O queue pairs on each of the hosts by selectively changing the number of I/O queue pairs of the reserved pool.
