Silent Data Corruptions at Scale

Understand

Silent Data Corruption (SDC) can have negative impact on large-scale infrastructure services.

• SDCs are not captured by error reporting mechanisms within a Central Processing Unit (CPU) and hence are not traceable at the hardware level.
• However, the data corruptions propagate across the stack and manifest as application-level problems.
• These types of errors can result in data loss and can require months of debug engineering time.
