Introduction to ECC Servers (引言)

In the era of digital transformation, the role of Error-Correcting Code (ECC) servers has become indispensable. As data centers process exabytes of information daily, even a single bit error in memory can lead to catastrophic system failures. ECC servers, leveraging advanced error correction techniques, ensure data integrity across mission-critical applications. This document provides a comprehensive analysis of ECC server technologies, covering architectural innovations, practical implementations, and optimization methodologies.
