Backplane only; no drives, host controller, chassis or cables are implied. Listed drive counts are supported connections, not installed drives. Verify the exact chassis revision, power/data cabling, host controller and drive protocol. A SAS/SATA-only variant is not an NVMe backplane; hybrid capability applies only to the explicitly specified ports.
