A first endpoint comprises a fabric attach point for attachment to a memory fabric, a first media controller, and a first non-volatile memory media. The memory fabric comprises a reliability zone comprising the first endpoint and at least a second endpoint. The first media controller is configured to receive, from at least one processor coupled to the first endpoint via the at least one fabric attach point, a memory fabric store command to store an object in the reliability zone. The first media controller is further configured to store the object in the first non-volatile memory media, to receive from the second endpoint a message indicating that the same object has been stored by the second endpoint, and to send to the at least one processor a single acknowledgement indicating that the at least one object has been stored in both the first and second endpoints of the reliability zone.
