HETEROGENEOUS INPUT/OUTPUT (I/O) USING REMOTE DIRECT MEMORY ACCESS (RDMA) AND ACTIVE MESSAGE

摘要

Methods and apparatus to provide heterogeneous I/O (Input/Output) using RDMA (Remote Direct Memory Access) and/or Active Message are described. In an embodiment, information is exchanged between an embedded system and a storage device via a source device. The embedded system and the storage device exchange information over a first link and a second link instead of a third link in response to a transfer rate of the first link (coupled between the embedded system and the source device) being faster than a transfer rate of the second link (coupled between the source device and the storage device). The third link is capable to directly couple the embedded system and the storage device. Other embodiments are also disclosed and claimed.
