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.

Managing distribution of I/O queue pairs of a target among hosts

According to an example, coordination of adjustments to network frame hold time parameters between network devices in a network is initiated based on a trigger condition. Time data may be obtained from a plurality of network devices in the network, where the time data describes a network frame hold time parameter of each network device in the plurality and a network frame processing time of each network device. A set of affected network devices affected by network back pressure in the network, and a set of non-affected network devices in the plurality not included in the set of affected network devices, may be determined. Based on the time data, a pairing may be determined between a time-available network device from the set of non-affected network devices and a time-needed network devices, from the set of affected network devices, to receive an allocation of time credit from the time-available network device.
