Supermicro CSE-826BE1C4-R1K23LP 2U server chassis 12×3.5″ hot-swap 4×2.5″ NVMe redundant 1200W Titanium

Chassis for dense 2U storage

The Supermicro CSE-826BE1C4-R1K23LP is a 2U rackmount chassis designed for storage-heavy workloads. It holds twelve hot-swap 3.5-inch bays and four hot-swap 2.5-inch NVMe bays on a 12Gbps expander backplane. Redundant 1200W Titanium power supplies with PMBus 1.2 deliver 96%+ efficiency. Seven low-profile expansion slots support add-in cards.

Verify motherboard size and backplane cabling

Confirm the motherboard measures no more than 12 by 13 inches for E-ATX fit; the rear 2.5-inch option is only supported with a 12 by 13 board. Ensure the system provides enough 12Gbps SAS cables or a compatible HBA to drive the expander backplane. Check that the 8cm PWM fans meet the thermal design of the chosen processors, rated up to 205W each. Validate rack depth clearance for the 25.50-inch chassis length.

Replaces smaller 2U or non-redundant enclosures

This chassis upgrades from 2U units limited to eight 3.5-inch bays or lacking NVMe hybrid slots. The jump is worth it when a single node must serve both capacity and latency-sensitive tiers without a separate JBOD. It also supersedes builds using single power supplies by adding Titanium redundant units. Buyers needing full-height cards or more than seven low-profile slots should consider a different form factor.
