Low Profile SlimSAS SFF-8654 8x 74P to 2 U.2 SFF-8639 with 15P Power Cable

The Low Profile SlimSAS SFF-8654 8x 74P to 2 U.2 SFF-8639 with 15P Power Cable is a hybrid cable assembly engineered for enterprise storage systems requiring high-speed data transmission and integrated power delivery. This solution converts a single 8-lane Low Profile SlimSAS host interface into two independent U.2 (SFF-8639) interfaces, each equipped with a dedicated 15-pin power connector. Designed for space-constrained environments, the low-profile connector ensures compatibility with ultra-slim servers while delivering robust performance for NVMe storage deployments. The cable simplifies cabling infrastructure, improves airflow management, and supports next-generation storage devices with optimal signal and power integrity.

Features

• Integrated Power and Data: Combines PCIe data transmission (up to PCIe 5.0) and power delivery in a single cable, reducing clutter.
• Low Profile Design: LP SlimSAS connector (6.5mm height) enables deployment in high-density servers with limited clearance.
• Dual U.2 Connectivity: Efficiently splits one 8x host port into two U.2 interfaces for connecting NVMe SSDs.
• High-Speed Performance: Supports data rates up to 32 GT/s (PCIe 5.0), ensuring bandwidth for high-performance storage.
• Enhanced Signal Integrity: Precision engineering with impedance matching and multi-layer shielding minimizes signal loss and EMI.
• Reliable Power Delivery: Integrated 15-pin SATA power connectors provide stable power (up to 9A per connector) for U.2 devices.
