Abstract: Examples herein relate to managing data and network bandwidth. In an example implementation, a method includes monitoring a first location having a local volume and a local gateway and monitoring a second location having a first remote volume and a remote gateway. The method also includes determining a bandwidth requirement for a second remote volume at the second location and configuring the local gateway and the remote gateway for the bandwidth requirement. The method also includes adjusting the local gateway and the remote gateway when the bandwidth requirement changes.

Abstract: Example implementations relate to hard zoning capabilities for devices using Internet small computer system interface (iSCSI) protocol. For example, a method includes creating a virtual local area network (VLAN) at an Ethernet switch between an initiator and target adapter. The method includes assigning an access control list (ACL) to the VLAN, The method includes segregating a device of a plurality of devices connected to the SAN into a zone group. The method also includes controlling access of a zone group based on the ACL and frame filtering.

Abstract: In one implementation, a non-transitory machine-readable storage medium may store instructions that upon execution cause a processor to: determine, by a network device, path information for a plurality of paths in a computing fabric, the path information identifying alternative paths to access namespaces; determine, by the network device, a first portion of the path information that is associated with a first host; and provide, by the network device the first portion of the path information to the first host.

Abstract: Examples disclosed herein relate to identification of an alternate principal member port by a target device in a SAN. In some examples, a target device in a SAN may determine that a principal member port of a target driven peer zone on the target device is likely to fail based on diagnostic information related to the principal member port. The target driven peer zone may be configured in the SAN via the target device. In response to determining, the target device may identify an alternate principal member port on the target device. The target device may perform an action to indicate the alternate principal member port as the principal member port.

Abstract: An example system that includes a storage system controller to control a storage array. The storage system controller is to generate, in response to a logical unit change in the storage array, an in-band state change notification that includes in its payload an application-level-rescan-required notification.

Abstract: Examples relate to enabling auto-configuration and management of storage resources. In some examples, an Internet group management protocol (IGMP) announcement is received from an end device of a number of end devices in a software defined network (SDN) environment. A storage network fabric map is updated to include the end device based on the IGMP/multicast announcement, where the storage network fabric map describes a network topology of the end devices in the SDN environment. At this stage, a device port of the end device is added to a virtual local area network (ULAN). In response to determining that the end device matches a policy template, parameters of the template policy are applied to the device port.

Abstract: In some examples, fabric driven NVMe subsystem zoning may include receiving, from a non-volatile memory express (NVMe) Name Server (NNS), a zoning specification that includes an indication of a host that is to communicate with a given NVMe subsystem of an NVMe storage domain. Based on the zoning specification, the host may be designated as being permitted to connect to the given NVMe subsystem of the NVMe storage domain. An NVMe connect command may be received from the host. Based on the designation and an analysis of the NVMe connect command, a connection may be established between the given NVMe subsystem of the NVMe storage domain and the host.

Abstract: Examples include registration with a storage networking repository via a network interface device driver independent of a storage initiator. Some examples include registration with a storage networking repository, provision of a state change registration to the storage network device, and acquisition of login information for storage targets from the storage networking repository, each via a network interface device driver and independent of a storage initiator and a storage protocol driver.
