Connects a SlimSAS 8X host to two OCuLink 4X ports for SAS, SATA and NVMe drives with 80 cm routing length

  • Connects Broadcom 95xx tri-mode controllers to dual OCuLink 4X ports
  • Supports SAS, SATA and NVMe devices over PCIe Gen4 bandwidth
  • 74-pin SFF-8654 to two 36-pin SFF-8611 connectors with impedance matching
  • 80cm length suits server chassis and workstation cable routing
  • Plug-and-play installation enables storage expansion without complex configuration

Broadcom 95xx Tri-Mode Adapter Cable

The Vszerda RSL74-6658 connects a SlimSAS 8X host port to two OCuLink 4X ports using SFF-8654 74-pin and SFF-8611 36-pin connectors. It is built to Broadcom line-order standards for the 9560, 9580 and 9500 series controllers. The 80cm length suits internal routing in enterprise servers and high-performance workstations.

Builders Using Broadcom 95xx Series Controllers

This cable suits administrators adding NVMe, SAS or SATA drives to compatible MegaRAID or HBA tri-mode adapters. It is not for systems lacking a SlimSAS 8X host connector or for direct drive attachment without a supported Broadcom 95xx series controller.

Single 74-pin to Dual 36-pin Connector Layout

The defining specification is the SFF-8654 74-pin plug splitting to two SFF-8611 36-pin receptacles. This exact pinout enables one 8X controller port to drive two independent 4X device links for tri-mode storage configurations.

Questions about this item

What signal integrity limit appears first when the 80cm cable runs at PCIe Gen4 speeds?

The 74-pin SFF-8654 and dual 36-pin SFF-8611 connectors use precise impedance matching to minimise loss, keeping the link within spec for Gen4 bandwidth across the full 80cm length.

Does the cable add noticeable heat or power draw when the controller drives NVMe, SAS and SATA devices all day?

As a passive copper assembly it draws no extra power and generates no measurable heat; the Broadcom 95xx tri-mode controller handles all signal conditioning.

Which controller must already be installed for this 74-pin to dual 36-pin cable to work?

A Broadcom 95xx series tri-mode adapter such as the MegaRAID 9560, 9580 or HBA 9500 with an SFF-8654 8X port is required.
