DiLinker SlimSAS 8X to 2x OCuLink 4X Cable - Tri-Mode Connectivity

In this review of the DiLinker SlimSAS 8X to 2x OCuLink 4X cable, the bottom line is simple: this cable is for system builders and server administrators who need a compact, reliable internal interconnect to split a SlimSAS 8X host into two OCuLink 4X ports while preserving high throughput. The reviewer found the cable to be built to Broadcom line order standards and especially suited to systems using Broadcom 95xx tri-mode controllers; the single biggest reason to buy is the combination of precise connector design and support for SAS, SATA and NVMe over PCIe Gen4, which keeps modern storage arrays running at expected speeds.

Key Features

• Broadcom compatibility: Manufactured to Broadcom line order standards for seamless operation with 95xx series tri-mode controllers such as MegaRAID 9560/9580 and HBA 9500 series.
• Tri-mode connectivity: Converts one SlimSAS 8X host adapter into two separate OCuLink 4X ports to support SAS, SATA, and NVMe devices in mixed storage environments.
• PCIe Gen4 capable: Engineered to enable full utilization of PCIe Gen4 bandwidth so NVMe SSDs and high-speed SAS links can perform without being bottlenecked by the cable.
• Durable connectors: Uses robust SFF-8654 74-pin and SFF-8611 36-pin connectors with impedance matching to minimize signal loss and preserve data integrity.
• Practical length: At 80cm the cable provides enough reach for a wide range of server chassis and workstation internal routing while keeping a tidy layout.

Who It's For

The cable is aimed at IT professionals, system integrators, and advanced enthusiasts who populate servers or workstations with mixed SAS, SATA, and NVMe storage and who rely on Broadcom 95xx tri-mode controllers. It is particularly useful where a single SlimSAS 8X port must feed two separate device banks or cages via OCuLink connections.

Those who should look elsewhere include users who need external or longer runs beyond 80cm, or who require passive, legacy-only SATA splitters; this product is optimized for internal routed connections and modern tri-mode controller environments.

Pros & Cons

Pros

• Broadcom line order compatibility ensures predictable behavior with supported controllers.
• Supports SAS, SATA, and NVMe so arrays can mix device types without additional adapters.
• Designed for high-speed transfers and PCIe Gen4 bandwidth to reduce potential bottlenecks.

Cons

• Fixed 80cm length may be too short for some large chassis or external routing needs.
• Not intended for external use or configurations outside supported tri-mode controllers.

Our Verdict

The DiLinker SlimSAS 8X to 2x OCuLink 4X cable is a solid, value-minded choice for builders who need a reliable internal splitter for Broadcom tri-mode controllers. Its Broadcom-standard construction, durable connectors, and PCIe Gen4-capable design make it a practical component when splitting a SlimSAS port to service two OCuLink device banks, provided the 80cm length suits the chassis layout.

Frequently Asked Questions

Will this work with Broadcom MegaRAID 9560?
Yes. It is manufactured to Broadcom line order standards and is compatible with 95xx series tri-mode controllers such as MegaRAID 9560.

Can the cable carry NVMe over PCIe Gen4?
Yes. The cable is designed to enable full utilization of PCIe Gen4 bandwidth for NVMe SSDs when used in supported configurations.
