Overview
Chenbro's rackmount storage chassis line covers the disk tiers that sit behind GPU compute in an AI factory. The RM41824 is a 4U modular enclosure that concentrates 2.5-inch SAS/SATA hot-swap bays into a space-saving layout, paired with an E-ATX motherboard position and a CRPS power supply cage — the standard combination for high-density all-flash or mixed-flash storage nodes.
The RM31616 moves in the other direction on density: a 3U chassis holding sixteen 3.5-inch SAS/SATA hot-swap bays for bulk-capacity tiers where HDDs still deliver the lowest cost per terabyte. Like the RM41824 it accepts an E-ATX board and CRPS power, so a single platform family can serve both flash and disk tiers. The RB13804 adds a 1U tri-mode option: four hot-swap 3.5-inch bays that accept SAS, SATA or NVMe drives in the same slots, with a 735.0 x 438.5 x 43.2 mm footprint.
Together these chassis give integrators a consistent mechanical and power story — CRPS supplies, E-ATX boards, hot-swap drives — while scaling from a 1U edge cache up to 3U and 4U storage nodes. They are the mechanical layer for AI dataset staging, checkpoint storage and secondary storage that keeps NVMe tiers from absorbing bulk data.
Key Benefits
Three density tiers — 1U tri-mode, 3U 16-bay and 4U modular — from one vendor and one power standard. Tri-mode flexibility on the RB13804 accepts SAS, SATA or NVMe in the same bays. CRPS redundant power across the line. E-ATX board support for real server platforms, not just storage controllers. 19-inch rackmount mechanicals consistent with the rest of an AI rack build.
Applications
AI dataset and checkpoint storage nodes, warm and cold storage tiers behind GPU clusters, NVMe flash cache arrays with tri-mode drives, JBOD and secondary storage chassis, edge storage nodes in 1U, and ODM/OEM barebone programmes.
