advertisement: Until recently, most high-availability systems were “hand-rolled” with proprietary architectures. The Advanced Tele - com Computing Architecture (ATCA) and MicroTCA specifications from the PICMG organization, collectively known as xTCA, have changed this regime. The xTCA platforms provide a systematic approach to building standard, reliable, modular, network-centric systems with multi-vendor support. xTCA features include redundancy, cooling, fault isolation, ESD protection, rapid MTTR, and advanced system management. The xTCA specifications were developed and fine-tuned to provide availability as high as 99.999%. This is equivalent to an average system downtime of less than 5.26 minutes each year, using standard commercial off-the-shelf enclosures and boards! For the first time in embedded system engineering, there is a costeffective, standard commercial approach to building high-availability systems. The Network Rules Figure 2.
