Abstract: In some examples, to define a connection path of an initiator to target ports of a plurality of controller nodes that manage access of data in a storage system, a provisioning system determines loads of respective sets of target ports, and selects a selected set of target ports from among the sets of target ports for inclusion in the connection path based on the determined loads.

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.

Abstract: In some examples, universal host and NVMe™ storage domain discovery for NVM Express™ over Fabrics (NVMe-oF™) may include broadcasting location parameters to a host and a plurality of NVMe™ storage domains for discovery of a NVM Express™ over Fabrics (NVMe-oF™) service. Based on host parameters and NVMe™ storage domain parameters received in response to the broadcast location parameters, the host and the NVMe™ storage domains may be respectively registered with the NVMe-oF™ service. A mapping that indicates a specified NVMe™ storage domain that is to communicate with the host may be obtained. Communication may be implemented between the host and the specified NVMe™ storage domain by forwarding the mapping and associated discovery target parameters to the host to implement discovery of the specified NVMe™ storage domain by the host, and connection of the specified NVMe™ storage domain to the host.

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: A technique includes hosting an Internet Storage Name Service (iSNS) server on a network switch to provide access to a plurality of subnets; and configuring the iSNS server to be an active server for a first subnet of a plurality of subnets and to be a backup server for a second subnet of the plurality of subnets.
