Vszerda MCIO 8i to Dual SFF-8643 Cable

This 80 cm cable converts a single MCIO 8i 74-pin port into two SFF-8643 Mini-SAS HD connectors. It is built for server and data-centre environments that need high-density SAS or PCIe 5.0 links between backplanes, controllers or expanders.

Suited For And Not Suited For

Suited for integrators wiring 32 GT/s SAS or PCIe 5.0 connections in dense chassis where a secure latch matters. Not suited for installations that need a different connector pitch, a longer reach than 80 cm, or a cable rated for a signalling standard other than SAS or PCIe 5.0.

32 GT/s Over 8 Lanes

The assembly supports 32 GT/s across eight differential pairs and is backward compatible with PCIe 4.0 speeds. Silver-plated OFC conductors and an aluminium shell maintain signal integrity at the full 32 GT/s rate.

Questions about this item

Does the 80 cm MCIO 8i to 2xSFF-8643 cable come with any extra adapters or mounting hardware, or is it just the cable?

The package contains only the 80 cm MCIO 8i to 2xSFF-8643 cable itself; no additional adapters, brackets or screws are included.

Should I choose a different length or connector count for a PCIe 5.0 server backplane that needs four 8643 ports?

This model provides two SFF-8643 connectors from a single MCIO 8i plug; if four 8643 ports are required you would need two of these cables or a different cable with four 8643 ends.

What does the 32 GT/s rating mean when the cable is installed in a PCIe 5.0 storage array?

The cable supports the PCIe 5.0 32 GT/s standard across eight lanes and is backward compatible with PCIe 4.0, so it can carry full-gen 5.0 bandwidth between the controller and the backplane.
