50cm PCIe 4.0 SFF-8654 8i 74Pin to Dual SFF-8643 4i Mini SAS HD Fanout Cable, MCIO Slimline SAS Internal Breakout Cable for Server RAID & NVMe Backplane

This 50-centimeter internal Slimline SAS fanout conversion cable features one SFF-8654 8i 74Pin MCIO host connector that fans out to dual SFF-8643 4i Mini SAS HD target ports. It connects next-gen SlimSAS RAID/HBA controllers to traditional SFF-8643 storage backplanes for mixed SAS/NVMe server storage systems.

Compliant with SFF-TA-1016 MCIO and SAS 4.0 specifications, the cable retains complete 8-lane bandwidth split into two independent 4-lane channels without performance degradation, supporting both high-speed NVMe SSD and SAS/SATA hard drive arrays. High-purity tinned copper conductors wrapped in aluminum-mylar shielding effectively isolate electromagnetic noise from internal power supplies and cooling fans, enabling stable 24/7 non-stop heavy workload operation in data centers.

The short 0.5-meter structure avoids tangled excess cables and simplifies internal cable management. Every SFF-8643 connector comes with reinforced locking latches to prevent unstable contact caused by long-term fan vibration, and gold-plated contact pins resist oxidation for thousands of plug cycles.

Perfect for enterprise storage hardware upgrades, dual-channel RAID array assembly, high-density NVMe server deployment and large-capacity NAS system expansion, compatible with all mainstream brand rack servers and storage adapters.
