A method and apparatus for connecting between a serial fibre channel link and a global memory provide a bidirectional high throughput path for enabling reliable communications and translation from the fibre channel format to the format required by the global memory. The apparatus includes, in series from the fibre channel link, a bidirectional physical interface, a bidirectional conversion circuitry for converting between an electrical protocol from the fibre channel and a high speed conventional protocol such as a PCI bus, a bidirectional lower machine controlled by a central processing unit and able to add block protection words to the passing data stream, and for separating the data stream into one of a plurality of pipes as directed by the CPU, an error detection and correction circuitry for adding yet additional error correcting data to the data stream as it written in the global memory and for detecting and correcting, if possible, any errors in data being retrieved from global memory. The apparatus further includes dual port random access memories for buffering between the error detection and correction circuitry and the global memory. A secondary port interface is provided, connected to the CPU bus, for providing information to configure at least conversion circuitry.
