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.
