Soft Error Considerations for Computer Web Servers

Soft errors are caused by cosmic rays striking sensitive regions in electronic devices. Termed as Single Event Upset (SEU), in the past this phenomenon mostly affected the high altitude systems or avionics. The small geometries of today's nanodevices and their use in high-density and high-complexity designs make electronic systems sensitive even to the ground-level radiation. Therefore, large computer systems like workstations or computer web servers have become major victims of single event upsets. Given that the idea of cloud computing is an unavoidable trend for the next generation internet, which might involve almost every company in the IT industry, the urgency and criticality of the reliability rise higher than ever. This paper illustrates how soft errors are a reliability concern for computer servers.
