Abstract
A system architecture, a method, and a computer program product are disclosed for attaching remote physical devices. In one embodiment, the system architecture comprises a compute server and a device server. The compute server includes a system memory, and one or more remote device drivers; and the device server includes a system memory and one or more physical devices, and each of the physical devices includes an associated device memory. The compute server and the device server are connected through an existing network fabric that provides remote direct memory access (RDMA) services. A system mapping function logically connects one or more of the physical devices on the device server to the compute server, including mapping between the system memories and the device memories and keeping the system memories and the device memories in synchronization using the RDMA.
