Intel® Xeon® Processor E7 Family: Reliability, Availability, and Serviceability Advanced data integrity and resiliency support for mission-critical deployments EXECUTIVE SUMMARY Today‟s businesses increasingly depend on intensive and mission-critical applications. (RAS) are crucial issues for modern enterprise applications and services, as application of system downtime. ...Furthermore, the with the size of the servers, data, and Xeon® processor E7 family offers an provide error detection, correction, and I/O data paths. This feature set is a software vendors can build higher-level RAS across the entire hardware-software stack services. The Intel Xeon processor E7 family competitive price point and power solutions in the market. Intel® Xeon®-based servers to run data- Server reliability, availability, and serviceability IT shops that deliver mission-critical delivery failures can be extremely costly per hour likelihood of such failures increases statistically memory required for these deployments. . The Intel® extensive and robust set of RAS features in silicon to containment, and recovery in all processors, memory, powerful foundation upon which hardware and layers to provide overall server reliability from silicon to application delivery and delivers all these features at a highly consumption level compared to traditional RISC-based A failure of a single core business application can easily cost hundreds of thousands to millions of dollars per hour. Data Center Group Intel Corporation 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. Traditional approaches to server RAS limited their scope to only those errors that could be dealt with at the hardware level. In the traditional approach, an unrecoverable hardware error brings down an entire server and the applications running on it, causing major service disruption and costing users and businesses alike. This traditional approach is no longer sufficient. Today‟s crucial business challenges require the handling of unrecoverable hardware errors, while delivering uninterrupted application and transaction services to end users. Modern approaches strive to handle unrecoverable errors throughout the complete application stack, from the underlying hardware to the application software itself (Figure 1). Such solutions involve three components: (1) reliability, how the solution preserves data integrity; (2) availability, how it guarantees uninterrupted operation with minimal Intel Xeon Processor E7 Family: Reliability, Availability, and Serviceability Table of Contents Executive Summary .................................... 1 An Introduction to Reliability, Availability and Serviceability........................................ 1 Hardware Errors and Self-healing................2 Error Detection and Correction......................3 Memory Errors .........................................................3 Advanced RAS and the Intel Xeon Processor E7 Family...............................................4 The Intel Xeon Read the full WHITE PAPER The Intel® Xeon® Processor E7 Family RAS Features.
