InLine® MCIO x8 to 2x MiniSAS-HD SFF-8643 Cable, 0.5 m, Black

In enterprise server rooms and high-density storage arrays, connecting modern host controllers with MCIO x8 ports to existing SAS/SATA backplanes or drives with MiniSAS-HD SFF-8643 inputs often requires a reliable, high-performance internal link. This InLine® cable bridges that gap, delivering a direct 0.5 m connection that supports both legacy SAS/SATA and NVMe protocols over PCIe lanes.

• Cable length: 0.5 m (50 cm)
• Data protocol support: SAS, SATA, NVMe (via PCIe lanes)
• Lane configuration: 8 lanes (MCIO) to 2x 4 lanes (MiniSAS-HD)
• Max data transfer rate per lane: up to 24 Gbps (SAS-4 compatible)
• Impedance: 100 Ohm
• Conductor material: Copper
• Colour: Black
• Compliance: SFF-8643, SAS-4

Why choose it

Engineered for stable signal integrity, this cable ensures minimal crosstalk and consistent performance in demanding storage environments. Its robust construction and precise connector fit reduce the risk of disconnects, while the compact length minimizes clutter inside server chassis and storage enclosures.

Ideal use cases

• Connecting MCIO x8 host bus adapters or RAID controllers to SAS/SATA backplanes with MiniSAS-HD ports
• Upgrading or replacing internal storage cabling in servers, workstations, or JBOD enclosures
• Building custom storage solutions that require high-speed, multi-lane internal connections

Good to know

This cable is compliant with SFF-8643 and supports SAS-4 speeds, making it suitable for both current and next-generation storage deployments. The MCIO connector is designed for high-density applications, allowing more connections in less space compared to traditional connectors.
