METHOD AND APPARATUS FOR SECURING AND SEGREGATING HOST TO HOST MESSAGING ON PCIE FABRIC

摘要

A PCIe fabric includes at least one PCIe switch. The fabric may be used to connect multiple hosts. The PCIe switch implements security and segregation measures for host-to-host message communication. A management entity defines a Virtual PCIe Fabric ID (VPFID). The VPFID is used to enforce security and segregation. The fabric ID may be extended to be used in switch fabrics with other point-to-point protocols.

1. A PCI express switch in combination with a management system in a switch fabric having a point-to-point network protocol, comprising:
means for receiving an input from a switch fabric administrator defining subnets; means for generating a virtual fabric ID (VFID) for at least one defined subnet, tag packets of outgoing messages from at least one host with the virtual fabric ID, and means for determining if an incoming message to at least one host has a tag matching the virtual fabric ID; wherein receive processing for incoming messages is supported if the tag of the incoming message matches an approved virtual fabric ID and the message is dropped within the PCI express switch if the tag does not match the approved virtual fabric ID.
