Abstract: Example implementations include a method, a device, and a system for providing, by a device via a first port communicatively coupled with a first memory controller, read and write access to a shared namespace of a plurality of namespaces. A non-volatile memory storage of the device comprises the plurality of namespaces, the first memory controller being communicatively coupled with a non-volatile memory storage comprising the plurality of namespaces. The method further includes providing, by the device via a second port communicatively coupled with a second memory controller, read-only access to the shared namespace, the second memory controller being communicatively coupled with the non-volatile memory storage.
