Abstract
Currently, there is no scalable methodologies defined to locate a namespace on an NVMe-oF fabric. Therefore, it is necessary to configure a host with the NVMe™ Qualified Name (NQN) and transport information of the storage subsystem where the boot namespace is located or discover and enumerate all namespaces available to the host on an NVMe-oF fabric. With the current protocols, a host may need to perform many operations to locate the proper namespace and boot from the NVMe-oF fabric, making booting in a SAN environment an extremely slow operation and computationally expensive process. Embodiments herein support discovery, via a discovery controller, to provide a namespace resolution service able to facilitate a host to efficiently resolve a given namespace identifier to the corresponding subsystem port(s) through which that namespace is accessible.
