International Classification:

G06F015/173

US Classification:

709/238000

Abstract:

A system provides a router node to bridge a LAN and a System Area Network (SAN). The router node distributes LAN traffic across the SAN using a router management agent (RMA) and a filter agent (FA); the RMA includes a session management agent (SMA), a policy management agent (PMA) and a routing agent (RA); the SMA manages connections between remote clients and SAN nodes; the PMA maintains system operation policies; the RA with the FA direct LAN packets to SAN nodes; the FA handles conversion between a SAN protocol and a LAN protocol for packets within the SAN/LAN architecture. The cluster nodes include a node management agent (NMA); the NMA includes an SMA and PMA; these two agents perform the same functions as those in the router node; and a management node sets policies on the router node and includes a monitoring agent to query router node statistics.

Abstract:

A computer system which includes certain minimum capabilities in a system ROM. Device driver software is located in the system ROM or adapter ROM's. On boot the computer system collects these device drivers from ROM to develop a minimal system. If a removable medium such as a floppy disk or CD-ROM is present a configuration mode is entered when final driver files and operating system modules are stored on a selected hard disk. After this storage the device driver modules and operating system modules necessary to develop a boot image of the operating system are gathered and linked. The boot image is generated and stored, allowing use on the following boot operations. The computer system detects device changes and rebuilds the boot image as necessary. If the devices have remained the same the previously stored boot image is loaded and operating system execution commences.
