Internal SAS cable for dense server storage

The Vszerda SFF-8654 8i 74pin to dual SFF-8643 4i cable links a slimline backplane to a controller in servers, data storage arrays and workstations. It carries four channels at 24 Gbps for SAS and 8 GT/s for PCIe per channel, meeting SAS 4.0 and PCIe Gen3/4 specifications. The 50 cm length suits tight chassis layouts where space is limited.

Upgrade from bulkier Mini SAS HD assemblies

This cable replaces wider SFF-8643-only looms that occupy more backplane real estate and restrict airflow. The jump is worth it when a motherboard or HBA adds SFF-8654 8i ports and the existing cabling cannot reach or fit the new connector pitch. It also removes the need for an intermediate adapter that would add insertion loss and mechanical strain.

Fits slimline backplanes and standard controllers

The male SFF-8654 8i 74-pin plug seats directly into ultraport slimline receptacles on modern drive cages, while the dual female SFF-8643 Mini SAS HD ends attach to common RAID HBAs or motherboard headers. The black jacket and compact connector bodies free up routing space behind the backplane and reduce cable-management complexity in 1U and 2U enclosures.

Questions about this item

What clearance does the 50 cm SFF-8654 8i 74-pin connector need inside the chassis?

The Slimline SFF-8654 8i 74-pin connector is smaller than legacy Mini SAS HD plugs, so it fits in tight backplane bays and leaves room for airflow around adjacent cards.

Which end of the cable plugs in first when linking a backplane to a RAID controller?

Connect the single SFF-8654 8i 74-pin end to the backplane, then attach each SFF-8643 4i Mini SAS HD branch to the controller ports; reversing the order can bend the thinner Slimline latch.

When should the cable be inspected or replaced in a 24 Gbps SAS environment?

Check the latch tabs and cable jacket during any drive-tray service; replace the assembly if the 74-pin latch no longer clicks or if the 50 cm length shows kinks that could degrade 24 Gbps signal integrity.
