Rocket 7638D PCIe Gen5 x16 Switch Adapter
Powering Next-Generation AI, HPC, Scientific Research, and Media Production
The Rocket 7638D PCIe Gen5 Switch Adapter is a game-changing connectivity solution designed to eliminate bandwidth bottlenecks in high-demand computing environments. A dedicated 48-lane Gen5 PCIe switch chipset enables each adapter to intelligently allocate bandwidth to ensure hosted GPUs and NVMe storage operates at their maximum performance potential.
The unique hybrid 1x external CDFP-CopprLink port and 2x internal MCIO 8i ports configuration enables the Rocket 7638D to establish a direct, high-speed data pathway between hosted GPUs and NVMe storage arrays. The result is ultra-fast rendering, seamless real-time data processing, and accelerated workflows—making it the ideal choice for mission-critical applications in AI/ML, HPC, scientific research, and professional media production.
The Rocket 7638D is powered by industry proven PCIe Gen5 Switching Architecture, which delivers a full x16 lanes of PCIe bus bandwidth, and is capable of transmitting data at a staggering 60 GB/s, in either direction, with minimal latency! This level of sustained transfer speed is essential for data intensive applications including AI, ML, Scientific modeling and Engineering, and 3D design and animation workflows, all of which increasingly rely on high end GPUs and today’s fastest NVMe storage to maintain optimal performance.
Convert an MCIO 8i port into a Full-Sized PCIe 5.0 x16 Slot
The MCIO-PCIEX16-G5 Expansion bridge card can transform industry standard MCIO ports into PCIe Gen5 x16 slots. Each card can accept up to two MCIO connections and provide up to x16 lanes to the hosted PCIe device. This capability significantly boosts system connectivity, effectively overcoming the PCIe limitations of conventional motherboard design.
