Product Positioning & Applications

This high-speed PCIe 5.0 MCIO x8 to dual EDSFF cable is purpose-built for enterprise servers and high-density data centers. It converts a single MCIO port into two EDSFF connectors, enabling seamless integration of E1.S/E1.L/E3.S/E3.L form factor SSDs into existing server infrastructure. Designed for next-gen storage architectures, it is ideal for cloud computing, big data analytics, and high-performance computing workloads requiring reliable, high-bandwidth storage access. This listing is for 2.1 feet (65 cm) version, 1.6 feet (50 cm) alternative length is available separately for different wiring layout demands.

Specifications & Compatibility

Compliant with PCIe Gen5 (32 GT/s per lane, 8-lane configuration), backward compatible with PCIe Gen4 for broad platform support. The cable features a 74-pin MCIO x8 (SFF-TA-1016) male connector on one end and dual male EDSFF connectors on the other, with integrated 15-pin SATA power supply. It is fully compatible with all standard EDSFF form factors (E1.S/E1.L/E3.S/E3.L) and certified to meet enterprise server and data center interoperability requirements.

Construction & Material Advantages

Constructed with high-grade, low-loss materials and precision-engineered shielding, this cable ensures exceptional signal integrity even at maximum PCIe 5.0 speeds. Reinforced connectors provide robust mechanical durability, while optimized impedance control minimizes electromagnetic interference (EMI) and crosstalk. Built for continuous 24/7 operation, the cable delivers consistent, error-free performance in the high-density, high-temperature environments of modern data centers.

Installation Notes

The cable supports hot-swapping, allowing storage devices to be added or replaced without rebooting the host system, significantly reducing maintenance downtime. Installation is straightforward: simply connect the MCIO end to the host adapter and the EDSFF connectors to the SSDs, then connect the 15-pin SATA power lead to the server power supply. The cable is designed for indoor use only and is shipped in anti-static packaging to protect components during transit.
