In high-performance enterprise storage and server systems, efficient connectivity between array cards and storage devices is crucial for unlocking maximum throughput. The SFF-8654 8i 76P to 2*SFF-8643 array card connection cable serves as a professional breakout solution, bridging the high-density SlimSAS SFF-8654 interface with dual HD Mini SAS SFF-8643 ports to optimize data transmission in space-constrained environments.
Engineered to meet rigorous enterprise standards, this cable features a 76-pin SFF-8654 8i connector on one end—supporting 8 high-speed data lanes—and splits into two SFF-8643 connectors on the other, each delivering 4 lanes of transmission. Fully compliant with SAS 4.0 and PCIe 4.0 specifications, it supports data transfer rates of up to 24 Gbps per lane, enabling exceptional bandwidth for data-intensive tasks such as real-time analytics, large-scale backups, and NVMe storage operations. The 8i to dual 4i configuration efficiently distributes signal resources, making it ideal for connecting a single high-bandwidth array card to two separate storage modules or backplanes.
Crafted with high-quality 32AWG HF copper conductors and multi-layer shielding, the
SFF-8654 8i 76P to 2*SFF-8643 cable ensures superior signal integrity with 100±10% ohm impedance matching. Its robust shielding—combining aluminum tape and copper braid—effectively minimizes electromagnetic interference (EMI) and crosstalk, guaranteeing stable performance even in dense server racks. The compact SFF-8654 connector features a low-profile design that saves valuable internal space, while the secure latching mechanism on both connectors prevents accidental disconnections during maintenance or high-vibration operations.
Designed for universal compatibility, this array card connection cable seamlessly integrates with most enterprise-grade RAID controllers, storage arrays, and rack-mounted servers. It is specifically optimized for internal interconnections, as SFF-8654 and SFF-8643 are both industry-standard internal interfaces, making it a perfect fit for data centers, high-performance workstations, and JBOD storage systems. The cable supports backward compatibility with SAS 3.0 and PCIe 3.0 devices, ensuring seamless integration with existing hardware without the need for costly upgrades.
With a focus on durability and longevity, the cable adopts gold-plated PCB plating for enhanced corrosion resistance and reliable contact, supporting over 250 mating cycles for long-term use. Available in lengths ranging from 0.5m to 1m, it offers flexible routing inside server cases without obstructing airflow, a key factor for maintaining optimal cooling in high-density setups. RoHS compliant and built to operate stably in a temperature range of -40℃ to 85℃, it adapts to harsh data center conditions with consistent performance.
For IT professionals and system integrators, the SFF-8654 8i 76P to 2*SFF-8643 array card connection cable stands out as a cost-effective, high-performance solution. It simplifies complex storage architectures by splitting a single 8-lane interface into two 4-lane ports, maximizing connectivity efficiency without compromising speed. Backed by a 3-year warranty, it provides peace of mind for mission-critical applications, making it the go-to choice for upgrading or building high-density storage systems.
