12GB/s Mini SAS HD 4i plug (SFF8643 36P) to U.2 plug (SFF8639 68P) cable with SATA power Connector 1: 1 x SFF8643 male Connector 2: 1 x U.2 SFF8639 male 1 x SATA 15pin female connector 12GB/s Mini SAS HD 4i plug (SFF8643 36P) to U.2 plug (SFF8639 68P) cable with SATA power Data transfer rate: PCI Express 2.0 is up to 2 GB/sec; PCI Express 3.0 is up to 4 GB/sec. PCIe Gen 3 4 lanes 4 GB/s X 4 16 GB/s Conductor diameter: 32 AWG data wire; 24 AWG power wire Key benefits and why you need this cord Enables bridging between a SFF8643 Mini SAS HD 36P interface and a U.2 SFF8639 interface while delivering SATA power, expanding storage connectivity options. Supports speed data transfer aligned with PCIe generations up to PCIe Gen 3 x 4 lanes, yielding up to 16 GB/s in capable configurations. Built with dedicated data and power conductors to help maintain signal integrity and provide the SATA power for connected drives. Compact and rigid construction suitable for data center racks, servers, and workstation deployments that require flexible interconnects between SAS/SATA and U.2 drives. Compatible use scenarios Server storage expansion: Connect SAS/SATA backplanes with a SFF8643 interface to a U.2 host controller or adapter (SFF8639), with SATA power supplied through the same cable. Storage upgrade projects: Bridge from legacy Mini SAS HD connections to U.2 NVMe or SATA drives in workstations or servers that support U.2 interfaces. Data center rack deployments: Use in configurations where speed parallel data transfer is needed between controllers and 2.5 inch U.2 drives, while also powering SATA devices as required. Notes on specifications The cable is specified for 12GB/s Mini SAS HD 4i to U.2 connections with SATA power. Data transfer rate references cover PCIe 2.0 and 3.0 scenarios, with Gen 3 x4 totaling up to 16 GB/s. Conductors use 32 AWG for data paths and 24 AWG for power paths to support the required current and signal quality.
