## Problem Storage controller upgrades (restarts, more generally) can cause multi-second availability gaps. While the storage controller does not sit on the main data path, it's generally not acceptable to block management requests for extended periods of time (e.g. https://github.com/neondatabase/neon/issues/8034). ## Summary of changes This RFC describes the issues around the current storage controller restart procedure and describes an implementation which reduces downtime to a few milliseconds on the happy path.
