    Abstract: The invention relates to a method for providing improved reliability of any node attaching to an InfiniBand fabric, the method comprising the steps of: a) providing a first and a second physical Channel Adapter having a first and a second number of ports, b) providing program means for registering the first and second physical Channel Adapters as one logical Channel Adapter having a number of first and second ports, c) providing first and second caching means for storing first and second control information for the first and second Channel Adapter, d) providing system memory means for storing first and second control information, and e) providing means for copying the first control information from the system memory to the second caching means in case of a failure of the first Channel Adapter and for initiating an Automatic Path Migration from the first number of ports to the second number of ports.

    Abstract: A method and apparatus relates to hardware-to-hardware data transmission in computer systems, and in particular, it relates to method and system for operating I/O adapters attaching either one or more computing devices to an I/O periphery, to a network, or to other computing devices. It is proposed to operate a memory local to the network coupling adapter as a cache memory relative to a system memory associated with the one or more computing devices for storing transmission control information.

    Abstract: The expansion system allows hindling of a third class of functions in addition to the first class of non-redundant basic functions and the second class of functions wholly obtained via the basic functions. The third class of functions are only obtained in part via the non-redundant basic functions. A switch mechanism switches the processor between an external operating mode for handling the commands and microprogram instructions for the first class of functions and an internal operating mode for obtaining the second and third class of cuntions. In the latter mode, an auxiliary operator can supply additional functions for obtaining a new overall architecture.
