Experience with fibre channel in the environment of the ATLAS DAQ prototype “−1” project

Abstract Fibre Channel equipment has been evaluated in the environment of the ATLAS DAQ prototype “−1”. Fibre Channel PCI and PMC cards have been tested on PowerPC-based VME processor boards running LynxOS and on Pentium-based personal computers running Windows NT. The performance in terms of overhead and bandwidth has been measured in point-to-point, arbitrated loop and fabric configuration with a Fibre Channel switch. The possible use of the equipment for event building in the ATLAS DAQ prototype “−1” has been studied.
