    Abstract: 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.

    Abstract: PROBLEM TO BE SOLVED: To cope with imperfection of a technology concerning compatibility of a Fibre Channel (FC) switch.
    SOLUTION: A novel and unobvious data processing system, method, and computer program product according to an embodiment copes with imperfection of a technology concerning compatibility of a Fibre Channel (FC) switch, and directly acquires multiple port addresses from a SAN fabric by the FC switch. Using an N port connection from the last tier FC SAN switch, the system connects to the remaining SAN fabric, and utilizes an N port ID virtualization (NPIV) fibre channel function. The NPIV function enables one physical FC port (N port) to log in the SAN fabric a plurality of times and receive a unique N port ID upon every login. This enables one physical FC port (N port) to operate as a plurality of logical N ports.

    Abstract: An adapter or add-in card for use in a peripheral component interconnect (PCI) computer includes a universal module which couples the card to the PCI bus. The module includes a set of selectively programmable configuration registers which are loaded by a microprocessor on the adapter. A circuit arrangement on the module issues a command which inhibits the PCI processor from accessing the configuration registers until fully loaded. Another circuit arrangement presents the Expansion ROM base address register as a 'read/write' register or a read only register with all bits set to logical "0 " to the PCI computer. If the Expansion ROM base address register is presented as a read only register with all bits set to "0 ", the PCI computer concludes that no Expansion ROM exists on the add-in card, and its contents are not shadowed into the memory of the PCI computer. This disabling of the Expansion ROM causes memory space to be conserved in the computer. If the Expansion ROM is presented as a read/write register with non-zero values, the PCI computer concludes that an Expansion ROM exists and "shadows" its contents into the memory of the PCI computer.
