SFF-8644 to SFF-8088 Bridge Cable

This 2-metre hybrid cable connects SFF-8644 ports on newer SAS 3.0 host bus adapters to SFF-8088 ports on legacy SAS 2.0 storage enclosures. It serves system integrators and storage administrators who need to link mixed-generation equipment in rackmount JBOD, RAID or SAN deployments. The male-to-male copper assembly is built for passive, plug-and-play operation without external power.

Installation and Common Issues

The connectors are keyed for correct orientation; forcing them risks bent pins on the dense SFF-8644 side. Cable routing must respect the minimum bend radius of the twinaxial construction to avoid signal degradation. Speed negotiation between 12Gbps and 6Gbps endpoints is automatic, but mismatched firmware on older RAID controllers can occasionally prevent link-up until updated.

Capacity and Headroom

Each of the four differential channels carries up to 6Gbps, yielding 24Gbps aggregate throughput for RAID rebuilds and bulk data migration. The cable is rated at 6Gbps per channel, so SAS 3.0 links operate at their 6Gbps fallback speed rather than the full 12Gbps. For workloads demanding sustained 12Gbps per lane, a native SFF-8644 to SFF-8644 assembly is required.

Questions about this item

How can I confirm the 6 Gb/s per channel link is active after connecting the SFF-8644 to SFF-8088 cable?

Check the HBA or RAID controller BIOS and OS utilities for a negotiated 6 Gb/s link speed on each of the four channels; the cable auto-negotiates between SAS 3.0 and SAS 2.0 without manual setup.

What comes in the box and what must I source separately for the SFF-8644 to SFF-8088 connection?

The package contains the 2 m passive copper cable with male SFF-8644 and male SFF-8088 connectors; you must provide the host bus adapter, RAID card or JBOD enclosure with matching external Mini SAS HD ports.

Which cable version should I choose for a 6 Gb/s per channel link between a SAS 3.0 HBA and a SAS 2.0 enclosure?

Select the 2 m SFF-8644 to SFF-8088 model; it is backward and forward compatible, supports 6 Gb/s per channel across four channels, and meets SFF-8470 specifications for data-centre use.
