Lenovo D3284 10TB x 42 Expansion Enclosure | Storage, Rack Mount

Scale storage capacity where rack space is already committed. Lenovo D3284 10TB x 42 HD expansion enclosure is designed for dense enterprise environments that need more usable capacity without moving to a larger footprint. With support for 42 drives, it gives IT teams a practical way to extend storage for backup repositories, archive tiers, virtualization support, and data retention workloads. This enclosure fits the kind of deployment where consistency matters: predictable expansion, centralized management, and a chassis built to slot into an existing Lenovo storage architecture. For teams comparing it against lower-density alternatives, the value is in consolidation. Fewer enclosures can mean simpler cabling, fewer rack units consumed per terabyte, and less operational overhead as capacity grows. It is a strong fit for organizations that need to keep critical data close to the compute layer while preserving room for future growth. When storage demand rises, this enclosure helps you add capacity in a controlled way instead of forcing a broader infrastructure change.
