Numerous systems have been designed which use virtualization to subdivide the ample resources of a modern computer. This paper presents Xen, an x86 virtual machine monitor which allows multiple commodity operating systems to share conventional hardware in a safe and resource managed fashion, but without sacrificing either performance or functionality.

This paper gives an overview of Remote Direct Memory Access (RDMA) over IP. The second part of the paper considers an RDMA over IP solution, giving background and current status. An architecture is described that is that currently being adopted by the RDMA Consortium and the RDDP WG in the IETF.

A remote direct memory access (RDMA) system is provided in which data is transferred over a network by DMA between from a memory of a first node of a multi-processor system having a plurality of nodes connected by a network and a memory of a second node of the multi-processor system. The system includes a first network adapter at the first node, operable to transmit data stored in the memory of the first node to a second node in a plurality of portions in fulfillment of a DMA request.

In one embodiment, a system comprises at least a first node and a second node coupled to a network. The second node comprises a local memory and a direct memory access (DMA) controller coupled to the local memory. The first node is configured to transmit at least a first packet to the second node to access data in the local memory and at least one other packet that is not coded to access the local memory.
