Supermicro CSE-847BE1C4-R1K23LP server chassis 4U 36x3.5" hot-swap SAS/SATA 1200W
A 4U rack chassis holding 36 hot-swap 3.5-inch SAS/SATA drives with dual backplanes, seven low-profile slots, seven 80 mm fans and a 1200 W titanium supply
- 36 hot-swap 3.5-inch bays for massive SAS/SATA storage capacity
- 1200W Titanium power supply with PMBus monitoring for efficient operation
- 24-port SAS3 12Gbps backplane enables high-speed drive connectivity
- 7 low-profile expansion slots provide flexible I/O configuration
- 7 high-performance 80mm fans deliver targeted chassis cooling
4U Chassis with 36 Hot-Swap Bays
This 4U server chassis supports motherboards up to 13.68 by 13 inches and provides 36 hot-swap 3.5-inch SAS or SATA drive bays with SES3 monitoring. An optional two-bay 2.5-inch hot-swap module can be added. Seven low-profile expansion slots are available for add-in cards. It is built for dense storage deployments that need direct-attached capacity in a single rack unit.
7 High-Performance Fans and Titanium Supply
Seven 80mm high-performance fans move air through the 4U enclosure to keep 36 drives and the backplane within thermal limits. The included 1U power supply delivers 1200 watts at Titanium efficiency with PMBus monitoring and measures 76 by 336 by 40 millimetres. A 1000-watt rating is also supported for lower-load configurations. Acoustic output rises with fan speed under heavy drive activity.
Dual Backplanes and SES3 Management
A 12-port 2U backplane handles up to eight 3.5-inch SAS3 or SATA3 drives plus four SAS3, SATA3 or NVMe devices, while a 24-port 4U single-expander backplane supports 24 3.5-inch SAS3 or SATA3 drives. SES3 on the 36-bay hot-swap cage provides enclosure-level status and drive health reporting without additional software. The PMBus interface on the power supply allows remote power telemetry through standard management tools.

Questions about this item
How do I install the 1200W power supply into the 1U bay, and what step is often missed?
Slide the 1U 1200W Titanium unit (W76xL336xH40mm) into the bay until the latch clicks, then connect the PMbus cable to the backplane so the system can monitor power health — skipping the PMbus link is the common oversight.
Which components will need replacement after extended operation?
The seven 80mm high-performance fans are the primary wear items; plan to swap them when noise or airflow drops, and the 1200W/1000W Titanium power supply may need replacement after its rated service life.
What is the first throughput limit reached when all 36 bays are active under sustained load?
The 24-port 4U SAS3 12Gbps single-expander backplane caps aggregate bandwidth at 12 Gbps per port, so total drive throughput hits that expander ceiling before the 12-port 2U backplane or drive media become the bottleneck.
