SlimSAS SFF-8654 8i breakout cable

This internal SlimSAS cable splits a single SFF-8654 8i connector into two SFF-8654 4i connectors. It carries SAS and PCIe 4.0 traffic at 24 gigabits per second over a 0.5 metre ribbon assembly. The 85-ohm impedance and 48 conductors suit servers, workstations and datacentre storage links where space is tight.

Practical limits of the 24Gbps interface

Signal integrity is specified for 0.5 metre; longer runs are not covered by the supplied data. The cable complies with the T10 Serial Attached SCSI standard extended for PCIe 4.0, so it handles both storage and add-in card traffic. Builders needing greater reach or a different lane split must choose another assembly.

Installation notes and common issues

The straight-to-straight, male-to-male connectors plug directly into backplanes or controller ports without adapters. Ribbon construction allows tight bends, but sharp folds can damage the 85-ohm lines. Verify keying on each 4i port before seating; forcing a misaligned connector is the usual cause of bent pins or intermittent links.

Questions about this item

Should I choose the 0.5 m or the 1.65 m length for my server chassis?

The 0.5 m version keeps cable routing tight in dense 1 U or 2 U servers, while the 1.65 m option reaches across larger 4 U chassis or between adjacent racks without slack.

What does the 24 Gbps rating mean once the cable is installed in a live system?

Each of the eight lanes runs at 24 Gbps, so an 8-lane controller can deliver the full PCIe 4.0 x8 or SAS-4 throughput to the connected backplane or drives.

Which interface standard does the SFF-8654 connector follow, and what speed does it cap in practice?

The cable follows the T10 SAS-4 specification and is extended for PCIe 4.0, limiting each lane to 24 Gbps with 85-ohm impedance.
