ARCTIC SlimSAS 8X to 2× OCuLink 4X 80cm cable 2 in 1 accessory

SKU CH-6MK4-MG2FD

Connects a SlimSAS 8X host adapter to two OCuLink 4X ports for SAS, SATA and NVMe drives using PCIe Gen4 bandwidth

  • Connects Broadcom 95xx tri-mode controllers via SlimSAS 8X to dual OCuLink 4X
  • Supports SAS, SATA and NVMe devices on a single 80cm cable assembly
  • Uses SFF-8654 74-pin and SFF-8611 36-pin connectors with impedance matching
  • Enables PCIe Gen4 bandwidth for high-speed NVMe SSD and SAS/SATA transfers
  • 80cm length suits internal routing in server chassis and workstation builds

Broadcom-compatible SlimSAS cable

This new cable connects a SlimSAS 8X host adapter to two OCuLink 4X ports. It is built to Broadcom line-order standards for the 95xx tri-mode controllers such as the MegaRAID 9560, 9580 and HBA 9500 series. The 80cm length suits internal routing in server chassis and workstations.

Splits one 8X link into two 4X links

The 74-pin SFF-8654 connector breaks out to two 36-pin SFF-8611 connectors. This lets you attach SAS, SATA and NVMe drives to a single controller port. Impedance-matched connectors preserve signal quality for PCIe Gen4 bandwidth.

Check controller and drive connectors first

Your host adapter must present a SlimSAS 8X port compatible with Broadcom 95xx tri-mode controllers. Each target device needs an OCuLink 4X receptacle. The cable does not convert protocols, so the controller must natively support the attached drive type.

Questions about this item

Will the SFF-8654 or SFF-8611 connectors need periodic replacement?

The SFF-8654 74-pin and SFF-8611 36-pin connectors are built for durable internal use and do not have a scheduled replacement interval.

What bandwidth limit appears first when driving two NVMe drives through the SlimSAS 8X link?

The single SlimSAS 8X host connection caps aggregate throughput at PCIe Gen4 x8, so both OCuLink 4X ports share that total bandwidth.

Does the 80cm cable add noticeable heat or power draw during all-day operation?

The passive cable draws no power and generates no measurable heat; only the attached controller and drives contribute to thermal load.
