METHOD, COMPUTER PROGRAM, AND APPARATUS FOR CREATION AND MANAGEMENT OF ROUTING TABLE FOR PCI BUS ADDRESS BASED ROUTING WITH INTEGRATED DID

摘要

PROBLEM TO BE SOLVED: To share PCI adapters between multiple blades.;SOLUTION: The present invention relates to a method for routing PCI transaction packets through switches between hosts and adapters in a distributed computing system that includes multiple route nodes, one or more PCI switches and PCI adapters, wherein each route node includes multiple hosts and one of the route nodes includes a PCI configuration manager (PCM). A table is created within specified one of switches and when a particular host is connected to the specified switch, a destination identifier including a set of bits designated by operating the PCM is entered to the table. The destination identifier is appended as an address to PCI packet directed through the specified switch from the particular host to one of the adapters. The destination identifier is used to determine that a PCI packet, routed through the specified switch from one of the adapters, is intended for the particular host.;COPYRIGHT: (C)2007,JPO&INPIT
