Intel® Xeon® Processor E7 Family for New RAS Servers: White Paper
Today’s businesses increasingly depend on Intel® Xeon® processor-based servers to run data-intensive and mission-critical applications. Server reliability, availability, and serviceability (RAS) are crucial issues for modern enterprise IT shops that deliver mission-critical applications and services, ...as application delivery failures can be extremely costly per hour of system downtime. Furthermore, the likelihood of such failures increases statistically with the size of the servers, data, and memory required for these deployments. The Intel® Xeon® processor E7 family offers an extensive and robust set of RAS features in silicon to provide error detection, correction, containment, and recovery in all processors, memory, and I/O data paths. This feature set is a powerful foundation upon which hardware and software vendors can build higher-level RAS layers to provide overall server reliability across the entire hardware-software stack from silicon to application delivery and services. The Intel Xeon processor E7 family delivers all these RAS server features at a highly competitive price point and power consumption level compared to traditional RISC-based solutions in the market.
An Introduction to Reliability, Availability, and Serviceability
Mission-critical applications such as database, enterprise resource planning (ERP), customer resource management (CRM), and business intelligence (BI) applications require newer technologies at better price points to deliver to their promise. Many of these applications also need to be available 24/7 on a wide area or global basis. While clustering and virtualization can help meet availability requirements, they are not adequate solutions for very large databases, BI, and high-end transactional systems. A failure affecting a single core business application can easily cost hundreds of thousands to millions of dollars per hour. All this evidences a need for scalable and highly resilient servers that are well suited for critical business applications and large-scale consolidation.
