Patent ID: 8595343

Claim:
A network comprising: a management module comprising a first root complex; a first server comprising a first endpoint coupled to the first root complex, wherein the first endpoint and the first root complex are located within a first PCIe domain, and wherein the first PCIe domain is configured to enable peer-to-peer transactions only between endpoints in the first PCIe domain; and a second server comprising: a second root complex; a second endpoint coupled to the second root complex; a third endpoint coupled to the first root complex and to the first endpoint, wherein the third endpoint is located within the first PCIe domain and sends data to the first endpoint via a peer-to-peer transaction, a PCIe host bridge adapter including a bridge, the second endpoint, and the third endpoint, the bridge to transfer data between the first PCIe domain and a second PCIe domain by the bridge being adapted to receive data from one of the second and third endpoints and to transfer the data to the other endpoint, wherein the second endpoint is located within the second PCIe domain, and wherein the bridge is not in either the first PCIe domain or the second PCIe domain.
