MCIO 74Pin to Dual SFF-8643 Breakout Cable
This 50 centimetre cable converts a single MCIO 74Pin 8X host port into two independent SFF-8643 Mini SAS HD 8X connections. It enables direct attachment of NVMe backplanes or RAID controllers to a PCIe 5.0 host adapter inside server chassis. The assembly is built for enterprise storage expansion projects requiring high-density internal wiring.
PCIe 5.0 Bandwidth and Signal Integrity
The cable is specified for PCIe 5.0 full-speed operation across both 8X branches, preserving maximum protocol throughput without throttling. Multi-layer shielding and high-purity conductors suppress electromagnetic crosstalk during sustained heavy-load transfers. Gold-plated contacts on the 36-pin SFF-8643 ends and the 74-pin MCIO plug resist oxidation and maintain tight mating force over long operational periods.
Verify Connector Types and Chassis Clearance
Confirm the host side presents an MCIO 74Pin 8X male receptacle and each target device accepts an SFF-8643 8X Mini SAS HD interface. The fixed 50 centimetre length suits standard server cases but may not reach distant drive bays in extended-depth enclosures. This cable does not carry sideband management signals; ensure the RAID card or backplane operates without them.

Questions about this item
Which PCIe 5.0 MCIO 74Pin 8X to dual SFF-8643 8X cable length should I choose?
The cable is supplied in a single 50 centimetre length designed to fit standard server chassis and keep internal routing tidy.
What does PCIe 5.0 support mean for actual throughput on each SFF-8643 link?
The cable is built to the PCIe 5.0 specification so each SFF-8643 8X path can carry the full protocol bandwidth without throttling.
Does the MCIO 74Pin 8X interface limit the dual SFF-8643 8X breakout in any way?
The MCIO 74Pin 8X input splits into two independent SFF-8643 8X channels, giving each link its own full 8-lane path.
