This adapter card converts the motherboard M.2 MKey NVMe PCIe port to the OCuLink based U.2 interface (SFF8639). It is designed to connect a U.2 SSD via an OCuLink SFF8611 to SFF8639 data cable. It uses a gold finger sinking process on a density low resistance circuit board and supports the NVMe PCIe standard. Key benefits Unlock U.2 NVMe storage by using an existing M.2 MKey NVMe PCIe port Reliable, lowresistance connections with goldplated contacts produced by a gold finger sinking process density PCB design promotes stable performance and longterm durability NVMe PCIe standard support ensures compatibility with modern NVMe SSDs through U.2 What it is An adapter card that bridges M.2 MKey NVMe devices to U.2 storage devices via OCuLink cabling Part of a family of adapters developed for other applications Compatibility M.2 MKey NVMe PCIe motherboard slots U.2 SSDs using OCuLink cables (SFF8611 to SFF8639 data cable) Technical highlights Gold finger sinking process for durable, lowimpedance contact surfaces density low resistance circuit board construction Supports NVMe PCIe standards for performant storage expansion Use scenarios Data center expansion: Connect U.2 NVMe drives to servers or workstations that have only an M.2 MKey NVMe PCIe slot, enabling capacity, performance storage without a motherboard upgrade Workstation upgrade: Add a U.2 NVMe SSD to a desktop or workstation to increase throughput for large datasets, databases, or professional applications Testing and benchmarking: Create a flexible test bench by swapping U.2 drives in and out via OCuLink cables to evaluate NVMe performance in a controlled environment Notes Requires an OCuLink SFF8611 to SFF8639 data cable to connect a U.2 SSD Uses the M.2 MKey NVMe PCIe interface and NVMe protocol for storage communication Designed for reliability and compatibility within the specified interfaces and standards
