For most, an External Accelerator Enclosure is a long-term investment. Choosing then deploying the right enclosure can have a dramatic impact on high-compute workflows, delivering the performance and reliability you need to fully exercise of your high-value Gen5 accelerator cards.
The Checklist
While many enclosure products claim Gen5 support, few can deliver on the three critical areas required for maximum performance: Bandwidth Reliability, Sustained Power, and Physical Compatibility.
HighPoint’s Rocket 8631D is one such solution. The following table compares this revolutionary enclosure to conventional solutions.
Feature | Conventional Solutions | RocketStor 8631D Advantage | Why It Matters to You (HPC/AI) |
Peak Power Supply Capacity | 850W or lower | 1300W Dedicated PSU | Prevents throttling and instability from transient power spikes of current and future Gen5 cards. |
Signal Integrity Technology | Passive Repeater or none | Astera Labs Gen5 Retimer | Guarantees the full 64GT/s bandwidth over the external cable with zero bit errors. |
Physical Card Support | Dual-slot max | Triple-Slot Width Design | Accommodates the largest, highest-TDP professional GPUs and accelerator cards. |
Thermal Management | Basic multi-fan | Self-monitoring, Smart Fan Control | Proactively manages thermal load on the hosted device, ensuring sustained, non-throttled performance for hours on end. |
External Standard | Proprietary or unknown | PCI-SIG CopprLink | Ensures open interoperability with CopprLink HICs and a standards-based future. |
The difference is clear - the RocketStor 8631D’s advanced signaling technology, broad form factor support and superior power delivery makes it the is the only choice for those who need uncompromised performance.
Conclusion: The RocketStor 8631D Doesn’t Compromise on Critical Features
In the world of AI and HPC, ultimate performance is measured by what can be sustained, not a theoretical peak. Conventional enclosures force considerable trade-offs—you either compromise on the power capacity needed for maximum TDP, or you compromise on the signal reliability needed for sustained Gen5 speed.
The RocketStor 8631D makes no such compromise. It is the only solution on the market that integrates a 1300W PSU, proven Astera Labs Gen5 Retimer technology, and support for 3-Slot devices into a single PCI-SIG CopprLink-certified chassis.
