Server Case Supermicro 836BE1C-R1K03B Rack Black

The Supermicro 836BE1C-R1K03B Rack Black is a 2U rackmount server chassis designed for dense storage and enterprise use. It supports up to sixteen 3.5" drives, accepts EATX motherboards and includes a redundant 1000 W Titanium-level (96%) efficiency power supply with PMBus. The chassis offers SAS3 (E1C) expander support and can be configured as JBOD or as a headunit. Physical dimensions are 437 mm (W) x 647 mm (D) x 132 mm (H).

Advantages

The case provides high power efficiency via a Titanium-level 1000 W redundant PSU with PMBus for monitoring and control, and full cooling redundancy through five hot-plug redundant fans and an adjustable air shroud. The design supports SAS3 expander solutions and flexible deployment modes (JBOD or headunit), enabling straightforward integration into storage-dense server racks.

Suitable for

• High-density storage servers and SAN/NAS appliance builds
• Data center racks requiring redundant power and cooling
• Enterprise environments needing modular JBOD or headunit configurations

How to use

Install an EATX motherboard and populate the 16 front-access 3.5" bays with compatible drives. Connect the included 1000 W redundant PSU to the system and use PMBus-compatible management tools for monitoring and configuration of power parameters. Fit the SAS3 expander as required for multi-drive connectivity and set the chassis to JBOD or headunit mode according to your storage architecture. Hot-plug fans allow servicing without powering down the system.

Recommendations

For reliable operation in data center environments, deploy with a compatible SAS controller or HBA, perform regular firmware updates for the expander and power supply, and ensure rack airflow follows the chassis front-to-back cooling orientation. Use enterprise-class 3.5" drives intended for continuous operation.
