SAS Slim 4.0 cable for dense server builds

This Fervit breakout cable connects a single SFF8654 74-pin Slimline port to two SFF8643 4i Mini SAS HD connectors. It is designed for administrators expanding PCIe Gen4 SAS storage inside low-profile or high-density chassis where space is limited. The slim form factor keeps airflow paths clear in tightly packed storage nodes.

Fits Gen4 backplanes and RAID controllers

The cable links a Gen4 Slimline Ultraport interface on a RAID controller or motherboard to dual Mini SAS HD ports on a backplane or expander. Its PCIe-compliant pinout preserves signal integrity across the breakout, letting you populate more drive bays without adding extra controller cards. No additional power adapters or active circuitry are required for the connection.

Precision pin alignment reduces signal loss

Factory-engineered pin mapping maintains stable high-speed transmission across both 4i branches, lowering the chance of link errors during heavy array rebuilds or sustained throughput workloads. The compact connector hoods sit flush in narrow drive cages, freeing neighbouring slots for additional cables or cooling. No software, drivers or mounting hardware are bundled with the cable.

Questions about this item

What throughput limit does the Gen4 SFF8654 8i interface impose under sustained workloads?

The Gen4 SFF8654 8i link runs at 4.0 speeds, so sustained throughput is capped at the PCIExpress Gen4 lane rate across the 8 lanes.

How much heat or noise does the cable add when the backplane runs all day?

The passive cable assembly generates no noise and negligible heat; thermal and acoustic load comes from the attached RAID controller and drives.

Which controller connector must my server already have to plug this breakout cable in?

Your RAID or HBA card needs a Slimline SFF8654 8i 74pin port to accept the host end of this cable.
