Rocket 7634D: The Cornerstone of External PCIe Gen5 Fabric

The HighPoint Rocket 7634D is the industry's first independent PCIe Gen5 External CDFP Adapter and is engineered to address the bandwidth and reliability challenges of external device expansion. By strictly adhering to the PCI-SIG CopprLink specification, the Rocket 7634D functions as the definitive external Host Interface Card (HIC), delivering uncompromised Gen5×16 performance for disaggregated computing and mission-critical storage.

Uncompromised Gen5 Performance & Connectivity

Core Technology: Dedicated Broadcom Switch

At the heart of the Rocket 7634D is the powerful Broadcom 89048 – 48-lane Gen5 Switch Chipset. This dedicated silicon is key to delivering clean, non-blocking bandwidth:

Maximum Throughput: The Rocket 7634D will fully utilize a PCIe Gen5×16 connection from the host platform to deliver up to 64 GB/s of dedicated, bi-directional throughput—vital for feeding high-performance accelerators.

Intelligent Lane Allocation: The 48-lane switch IC intelligently manages this bandwidth, ensuring the external port delivers the uncompromised performance necessary for today’s fastest NVMe storage and compute accelerators.

Widely compatible with Indstry Standard Cooprlink Devices

The Standard of Reliability: PCI-SIG CopprLink

The Rocket 7634D's compliance with the PCI-SIG CopprLink Specification is paramount to its professional-grade reliability and universal compatibility.

Universal Interoperability: Ensures seamless communication and connection with any CopprLink-compliant external device or cable, establishing an open ecosystem standard.

Signal Integrity: CopprLink defines the necessary electrical parameters to maintain the integrity of the 32GT/s Gen5 signal over the external cable link.

CDFP Connector: Chosen for its enterprise-grade reliability and ease of use, the CDFP (Compact Form-factor Pluggable) connector is the industry's most compact and secure external high-density I/O solution.

Full Ecosystem Support for Industrial Applications

The Rocket 7634D's compliance ensures it functions as a universal Host Interface Card (HIC), enabling it to serve as a critical bridge for connecting industrial servers and workstations to performance-hungry external compute devices and NVMe storage.

Key Features:

The combination of the Rocket 7634D and CopprLink-ready enclosures delivers:

Rapid Integration: pair the Rocket 7634D with validated, off-the-shelf NVMe Storage Enclosures, such as the RocketStor 6600 series, or eGPU Expansion Enclosures, such as the RocketStor 8000 series, for quick deployment into existing industrial server or workstation environments.

Maximum Performance: State of the Art PCIe Switching technology ensures that expensive external devices are never bottlenecked by outdated PCIe standards or tunnelling protocols.

Peace of Mind: The reliance on the PCI-SIG CopprLink specification guarantees compliance and interoperability, protecting your long-term hardware investments.

Engineered for Integration and Control

Designed for Space-Constrained Servers: The Rocket 7634D is built with system integration in mind. Its CEM Low-Profile form factor ensures the card fits seamlessly into compact, space-constrained server environments, maximizing rack density without sacrificing the massive Gen5×16 bandwidth it enables.

Firmware Customization and Project Support: The integrated Broadcom 89048 Switch and HighPoint’s engineering expertise enables flexible Firmware customization for customer defined projects. This makes the Rocket 7634D ideal for OEM solutions or looking to integrate HighPoint NVMe Storage or external PCIe expansion enclosures.

Expansion on Demand: Disaggregated Computing Solutions - External CDFP/CopprLink connectivity enables administrators to quickly add or remove accelerators and I/O devices to the host platform, as needed, simplifying integration and maintenance procedrues while freeing up valuable interior space for core hardware componentry.

Offset Power Consumption and Heat Management from Server and Workstation environments: The Rocket 7634D can enhances the efficiency and reliability of of compact server and workstation platforms. The external CopprLink connectivity enables demanding I/O and accelerator cards to be hosted outside of the chassis, effectively isolating sensitive computing hardware from waste heat and power deamnds of high-performance PCIe Gen5 devices.

Always In Control: HighPoint MPT Solution

HighPoint's MPT (Management, Performance, and Troubleshooting) solution provides system administrators and solution providers with the tools to maintain continuous oversight:

Health Status: Administrators are always in control of the connectivity health status.

Performance Monitoring: Real-time visibility into link status and performance metrics ensures the external Gen5 fabric is operating optimally, providing true peace of mind.
