Deep-dive on tsys4/5 storage controllers revealed:
- tsys4: 4-port SATA, all occupied; D3 SSD is USB 2.0
- tsys5: LSI SAS1068E (8-port, 5 free) + ICH10 SATA (2 free) + USB 3.0
Decision: move D3 (SK hynix SSD) to a tsys5 SAS port. Eliminates USB
bottleneck and consolidates all fast storage on tsys5: NVMe (local) +
D3 SSD + T5-SSD + 4 HDD exports.
Updated storage architecture, speed tiers, critical VM placement,
failure survival matrix, StorageClass design, and Friday plan.
