Migrating all servers (with months apart) to 8-bay hot-swap cases with backplane, and adding my remaining 6 #SMR HDDs to them (2 for each of the three servers) for a low-performance #RadosGW/S3 glacier type storage (with SSD DB-pool, but that's not the point).
Reducing the footprint of bulk/backup storage on my expensive CMR-drives.
