Peer direct mechanism for direct memory access across host devices

Abstract:

In one example, at least one peripheral interconnect switch obtains, from a first endpoint device, a message initiating a direct memory access data transfer between the first endpoint device and a second endpoint device. The message indicates an address assigned to the second endpoint device by a host device as a destination of the message. Based on the address assigned to the second endpoint device by the host device, the at least one peripheral interconnect switch identifies an address assigned to the second endpoint device by the at least one peripheral interconnect switch. In response to identifying the address assigned to the second endpoint device by the at least one peripheral interconnect switch, the at least one peripheral interconnect switch provides the message to the second endpoint device.
