Internal SAS cable RAIDSONIC MB206L-B slim 50 cm SAS 8i to OCuLink 4i

The Internal SAS cable RAIDSONIC MB206L-B slim 50 cm SAS 8i to OCuLink 4i is an internal connection cable designed for linking SAS controllers to OCuLink-compatible devices inside servers, RAID enclosures and storage systems. The cable measures 50 cm and features a single 8i SAS connector on one end and four separate 1i OCuLink connectors on the other end (combined as 4i). Its slim profile is intended for compact server layouts and systems where reduced cable bulk and improved airflow are priorities.

Advantages

The slim construction minimizes space usage and cable clutter in dense chassis and rack-mounted systems. A short, fixed 50 cm length limits excess cable that can obstruct airflow, helping maintain internal cooling efficiency. The combination of an 8i SAS connector and four 1i OCuLink connectors provides a direct, internal breakout from a single SAS port to multiple OCuLink devices without external adapters.

Suitable for

• Internal connections between SAS host adapters and OCuLink-compatible drives or expansion modules
• Compact server builds and small form factor storage enclosures
• RAID enclosures where a short slim cable reduces cable management complexity
• Systems where improved airflow and reduced internal obstruction are required

Key specifications

• Cable type: internal slim SAS to OCuLink breakout cable
• Connector configuration: 1 × 8i SAS to 4 × 1i OCuLink
• Length: 50 cm
• Intended use: internal server, RAID enclosure, storage system cabling
• Profile: slim, low-profile design for compact installations

How to use

Install the RAIDSONIC MB206L-B by connecting the 8i SAS plug to the SAS host controller or backplane SAS port. Route the slim cable within the chassis to avoid contact with moving components and maintain airflow. Connect each 1i OCuLink plug to the corresponding OCuLink device or module. Ensure all connectors are fully seated and that the cable is not kinked or sharply bent. Power off the system before installation or removal to prevent signal errors or device damage.

Recommendations

Use the cable in short internal runs to preserve signal integrity; avoid extending with passive adapters. Verify compatibility of the SAS controller and OCuLink devices for supported link speeds and protocols before installation. Keep the cable secured with existing chassis routing points or cable ties to prevent vibration and connector stress.
