SAS 4.0 adapter cable for enterprise storage

The Vszerda SAS 4.0 cable connects an SFF-8654 8i controller to SFF-8643 8i storage devices. It supports 12Gbps per lane for 48Gbps aggregate throughput across four lanes. The 50cm length suits internal server and high-density rack installations. This product targets IT professionals building or expanding enterprise-grade SAS storage arrays.

Verify controller and backplane connector types

Ensure your host bus adapter or RAID controller presents an SFF-8654 8i interface and that the target backplane or drive cage uses SFF-8643 8i ports. The cable uses male-to-male 36-pin connectors with a low-profile Slimline design on the SFF-8654 end. Confirm physical clearance for the secure locking mechanism within your chassis.

Low-profile design and locking connectors improve

The Slimline SFF-8654 connector reduces bulk in tight server enclosures where space is limited. Advanced EMI shielding preserves signal integrity in electrically noisy data-centre environments. Secure locking mechanisms on both ends prevent accidental disconnection during vibration or maintenance. These features support continuous operation in critical multi-lane SAS storage and RAID systems.

Questions about this item

Does the cable ship with any mounting hardware or do I need to buy brackets separately?

The cable is supplied as a single 50 cm assembly with SFF-8654 and SFF-8643 connectors; no brackets, screws or additional hardware are included.

Should I choose the 36-pin SFF-8643 version or a different pin count for my controller?

The 36-pin SFF-8643 connector provides four lanes at 12 Gbps each for 48 Gbps aggregate bandwidth, matching the 8i SFF-8654 end.

What does the 12 Gbps per lane rating mean when the cable is installed in a RAID array?

Each of the four lanes carries up to 12 Gbps, giving the RAID array a total of 48 Gbps throughput for sustained enterprise workloads.
