Drive converter bracket icybox MCIO 8i 74-pin SFF-TA-1016 to 2× OCuLink 42-pin 4i MB302L-B

The icybox MCIO 8i MB302L-B is a drive converter bracket that adapts a 74-pin SFF-TA-1016 (8i) interface to two OCuLink 42-pin 4i connectors. It enables connection of devices or host cards using OCuLink to systems with an SFF-TA-1016 port. The bracket is intended for use in storage expansions, drive enclosures and server or workstation retrofits where a direct conversion from SFF-TA-1016 to dual OCuLink 4i is required.

Advantages

The converter bracket provides a straightforward mechanical and electrical adaptation between SFF-TA-1016 and two OCuLink 4i interfaces, allowing compatibility between different generations of storage host cards and enclosures. By offering two OCuLink outputs from a single 8i port, it supports connection of multiple OCuLink devices without complex cabling changes. The design focuses on preserving signal mapping and maintaining a compact installation footprint suitable for drive bays and adapter slots.

Suitable for

• Upgrading servers or workstations to connect OCuLink-based storage devices
• Integrating OCuLink host cards with chassis or backplanes that provide an SFF-TA-1016 connector
• Expanding drive enclosures to accept OCuLink drives or modules
• Retrofit projects where physical interface conversion is required without replacing existing cabling

Key specifications

• Interface input: 74-pin SFF-TA-1016 (8i)
• Interface output: 2 × OCuLink 42-pin 4i connectors
• Purpose: mechanical and electrical conversion between SFF-TA-1016 and OCuLink
• Application areas: storage expansion, drive enclosures, server and workstation retrofit

How to use

Install the MCIO bracket into the appropriate drive bay or adapter slot and connect the SFF-TA-1016 plug to the host SFF-TA-1016 port. Attach OCuLink cables from the bracket’s two 42-pin connectors to the target devices or host cards. Ensure connectors are fully seated and any securing screws or latches are engaged. After physical installation, verify that the system firmware or operating system recognizes the attached devices and update drivers or controller firmware if required.

Recommendations

Use compatible OCuLink cables and ensure the connected host controller supports the mapping provided by the 8i to dual 4i conversion. Avoid forcing connectors and confirm power and signal requirements of attached devices match those supplied by the host system.
