Silent Data Corruption at Scale

by Caroline Trippel on Aug 15, 2022 | Tags: Datacenters, Errors, Reliability, Testing

Hyperscalers are reporting frequent silent data corruptions (SDCs)—a.k.a. silent errors or corrupt execution errors (CEEs)—in their cloud fleets caused by silicon manufacturing defects. Notably, SDCs at-scale exhibit error occurrence rates on the order of one fault...
