Very interesting, I hadn't seen SLOG before. It seems like there's a fairly similar core insight: placing data near where it's used can help with some system properties. They appear to be more latency-focused and we were (primarily) aiming at availability. The other different part of Physalia is our focus (again, for availability) on placement for 'blast radius'. That means we try limit the number of cells than any one failure (software, infrastructure, etc) can touch. Geo-replicated systems can have similar concerns, but I haven't seen the same level of focus on it as a key design goal.
