Supermicro RSC-R2UU-2E4E8R

The Supermicro RSC-R2UU-2E4E8R is a dedicated riser card engineered for Supermicro 2U rackmount servers. It provides a structured way to expand PCIe connectivity in high‑density systems where space, airflow and cable management are critical.

This riser is intended for use in compatible Supermicro chassis and motherboards only. It is typically deployed in data centers and enterprise IT environments to extend I/O capabilities without changing the server footprint.

• Optimized for 2U servers – Designed to fit Supermicro 2U rackmount systems, allowing horizontal installation of expansion cards in limited vertical space.
• PCIe expansion capability – Enables the addition of extra PCIe add‑in cards such as network adapters, storage controllers or accelerators, depending on server configuration and compatibility.
• Improved system flexibility – Supports more versatile configurations, for example adding dedicated HBAs, high‑bandwidth NICs or other specialized controllers to adapt the platform to specific workloads.
• Mechanical and thermal alignment – Form factor and connector positioning are tailored to Supermicro chassis for proper seating, cable routing and unobstructed airflow.
• Serviceability – Riser‑based expansion allows easier access to add‑in cards compared to tightly stacked vertical slots in low‑profile enclosures.

Typical usage scenarios

• Enterprise virtualization hosts requiring additional network ports or higher bandwidth links.
• Storage servers needing more dedicated HBAs or RAID controllers.
• Appliance or edge systems where PCIe expansion must fit within a 2U mechanical envelope.

Important note

Specific electrical characteristics, supported PCIe generation, slot layout and exact card compatibility depend on the server platform. For precise technical specifications and validated configurations, refer to the official Supermicro documentation for the RSC-R2UU-2E4E8R and the target chassis/motherboard.
