MCIO 8x 74P to 2 U.2 SFF-8639 with 15P Power Cable

The MCIO 8x 74P to 2 U.2 SFF-8639 with 15P Power Cable is a highly specialized hybrid cable assembly designed for enterprise storage systems requiring both high-speed data transmission and integrated power delivery. This innovative solution converts a single 8-lane MCIO (SFF-TA-1016) host interface into two fully independent U.2 (SFF-8639) drive interfaces, each with dedicated power connectivity through a 15-pin power connector. Engineered for next-generation data centers, it seamlessly integrates data and power transmission, providing a complete connectivity solution for high-performance NVMe storage deployment while simplifying cable management and improving airflow in server environments.

Features

• Integrated Data and Power Solution: Combines PCIe 5.0 data transmission with dedicated power delivery in a single cable assembly, eliminating the need for separate power cables and reducing cable clutter.
• Dual U.2 Connectivity: Efficiently fans out one x8 MCIO host port to two standard U.2 (SFF-8639) interfaces, enabling connection of two NVMe SSDs from a single host port.
• PCIe 5.0 Performance: Supports data rates up to 32.0 GT/s per lane, delivering the bandwidth necessary for high-performance NVMe SSDs in enterprise storage applications.
