CSE-846BE1C-R1K03JBOD Supermicro Rack 4U JBOD Chassis

High-Density 4U JBOD Storage Enclosure with SAS3 Expansion Architecture in the CSE-846BE1C-R1K03JBOD

The CSE-846BE1C-R1K03JBOD is a 4U direct-attached JBOD shelf designed to extend server storage without introducing a separate CPU or GPU platform, keeping compute on your existing hosts while centralising capacity in a serviceable enclosure. It integrates 24 x 3.5in hot-swap bays for SAS or SATA media, enabling nearline HDD tiers and bulk capacity pools with predictable operational handling.

Built around a SAS3 12Gb/s single-expander backplane, the CSE-846BE1C-R1K03JBOD connects through an external SAS HBA or RAID controller, allowing you to align PCIe expansion choices with the host server generation and slot topology. This approach preserves PCIe bandwidth and management boundaries on the server while delivering scalable storage attachment, streamlined drive replacement workflows, and consistent signal integrity across a dense 24-bay chassis for backup, archive, and high-capacity object or file tiers.

Why Choose the CSE-846BE1C-R1K03JBOD?

The CSE-846BE1C-R1K03JBOD provides an efficient density-to-capacity profile for enterprises that need to scale storage independently of compute, using a proven SAS3 expander design for consistent multi-drive connectivity. With 24 hot-swap bays in 4U and redundant 1U 1000W power supplies, the CSE-846BE1C-R1K03JBOD supports resilient deployments where serviceability, predictable cabling, and repeatable shelf expansion are priorities.

Supermicro engineers the CSE-846BE1C-R1K03JBOD for data centre practicality, focusing on validated chassis thermals, robust component selection, and rack-integration options that align with modern operational standards for uptime, maintainability, and lifecycle continuity.
