Performance Without Physical Limits

The RocketStor 8631D is not just an expansion box; it is a guaranteed high-performance solution for your most expensive compute resources. This is made possible

by the designs two key features:

The RocketStor 8631D is the industry's first enclosure to satisfy all these requirements simultaneously, making it the definitive platform for scaling accelerator performance across demanding vertical industry applications.

Unlocking Uncompromised Gen5×16 Performance

Maximum performance requires maximum technological commitment. The RocketStor 8631D is built around the fastest and most reliable connectivity standards available today:

Astera Labs Gen5 Retimer Technology: Integrated Retimer technology actively cleans, reshapes, and amplifies the PCIe signal. This is crucial for maintaining signal integrity and resetting the jitter and insertion loss budgets over the external cable, ensuring the host server sees a clean, low-latency Gen5×16 link for reliable, sustained throughput.

PCI-SIG CopprLink Standard: The enclosure features a robust, enterprise-grade external PCIe x16 Gen5 CDFP connector. By adhering to the PCI-SIG CopprLink specification, the RocketStor 8631D guarantees maximum bandwidth and seamless interoperability with HighPoint's CopprLink Host Interface Cards (HICs) and other compliant devices.

Application Focus: Dedicated PCIe Gen5 Fabric

When paired with a HighPoint External PCIe Switch Adapter, the RocketStor 8631D delivers true host-to-device PCIe Gen5 x16 performance for workloads such as scientific modeling, real-time analytics, and high-resolution rendering.

Engineered for Maximum TDP & Reliability

High-speed technology must be paired with superior physical engineering. The RocketStor 8631D is landmarking the industry's first enclosure to address the power and cooling requirements of next-generation accelerators, ensuring maximum TDP (Thermal Design Power) is sustained without throttling or component breakdown.

Unrestricted Power Delivery

Massive 1300-Watt PSU: The RocketStor 8631D upscales power support from 850W to 1300 Watts via a new integrated PSU. This immense capacity significantly widens the range of supported compute and accelerator cards from all vertical industry applications.

This guarantees dedicated, stable power delivery for performance-hungry workflows, preventing unexpected system shutdowns and prolonging component lifespan.

Advanced Thermal Management

Advanced, Intelligent Cooling Solution: A robust, reliable cooling system is a critical component of any expansion chassis. The RocketStor 8631D advanced Gen5 cooling solution is second to none.

The enclosure’s powerful cooling fans, backed by a bank of integrated hardware sensors and programmable Smart Fan Control, dynamically adjust airflow within the chassis to address thermal load in real time. This sophisticated system prevents performance throttling while keeping the solution’s acoustic performance in mind.

Streamlined Internal Layout: The RocketStor 8631D chassis was precision engineered to reduce cable clustering and minimize obstructions, ensuring superior, unhindered airflow directly over the most critical components.

Universal Physical Compatibility

Triple-Slot Width Design: The enclosure's chassis is specifically designed for universal PCIe GPU compatibility, including industry-standard full-height, 2-slot, and 3-slot PCIe Gen5 GPUs from all leading manufacturers. This commitment to physical sizing ensures maximum flexibility for integration projects.
