" summary

Clyso describes concrete upgrades: a Nautilus cluster moves live from old HDD nodes to NVMe and upgrades to Quincy with minimal interruption and measurable speed gains, demonstrating live HDD→NVMe migration. Work prototypes EC partial read support from a five‑year PR in a few days and shows strong performance while IBM and Bill’s team extend it toward partial writes. Ongoing builds include background defragmentation in deep scrubs, an online Ceph analyzer, S3 migration tooling, and optimizations for QLC flash and lower‑power CPUs to cut TCO.
