A fan-out cable (for example 8x to 2 × 4x, or 8x to 8 × SATA) splits those lanes across several device connectors. Use straight-through when the device is a single 8-lane backplane; use a fan-out when the device is individual drives or 4-lane connectors.\u003c\/p\u003e\n\n\u003ch3\u003eCan I use this cable for PCIe NVMe instead of SAS?\u003c\/h3\u003e\n\u003cp\u003eYes. SFF-8654 carries both SAS and PCIe, and 8-lane SlimSAS is a common input on PCIe NVMe backplanes. Deployments are typically Gen3 or Gen4. For PCIe 5.0 links, confirm the signal budget with your backplane vendor first — a passive 80 cm assembly at 32 GT\/s leaves very little margin.\u003c\/p\u003e\n\n\u003ch3\u003eWill a 12G SAS backplane work with a 24G controller?\u003c\/h3\u003e\n\u003cp\u003eYes. The link negotiates to the slowest component, so a 24G HBA with a 12G backplane and 12G drives runs at 12 Gb\/s. The cable itself does not limit the link.\u003c\/p\u003e\n\n\u003ch3\u003eDo I need to check the pinout before buying?\u003c\/h3\u003e\n\u003cp\u003eFor a straight host-to-backplane link on standard equipment, no — both ends follow the SFF-8654 8x pinout. If your backplane comes from a system vendor that re-purposes the connector, send us the model and we will check the lane order with you before you order.\u003c\/p\u003e\n\n\u003ch3\u003eWhat is the difference between SlimSAS and MiniSAS HD?\u003c\/h3\u003e\n\u003cp\u003eSlimSAS is SFF-8654: 74-pin for 8 lanes, 38-pin for 4 lanes, designed for SAS 4.0 and high-density PCIe. MiniSAS HD is SFF-8643: 36-pin, 4 lanes, the previous generation. They are not compatible; the board and backplane must both use the same standard.\u003c\/p\u003e\n\n\u003ch3\u003eIs the 80 cm version available in other lengths?\u003c\/h3\u003e\n\u003cp\u003eYes, this cable is also stocked in 70 cm for shorter 1U runs.
