Internal Mini-SAS Cable Supermicro CBL-MCIO-1255L4Y — MCIO x8 to 2× SlimSAS LP x4, 55 cm

Supermicro CBL-MCIO-1255L4Y is an internal Mini-SAS breakout cable that connects an MCIO x8 host or backplane interface to two SlimSAS LP x4 device connectors over a 55 cm length. The cable supports multi-lane SAS and SATA links and is intended for compact server and storage systems where space-efficient routing and reliable high-speed connections are required. Its design enables splitting an 8-lane interface into two independent 4-lane SlimSAS LP connections for direct attachment of drive bays, RAID cards or storage modules.

Advantages

The cable provides a compact, low-profile connection that reduces clutter inside racks and chassis while maintaining signal integrity for SAS and SATA multi-lane links. With a standardized MCIO x8 to SlimSAS LP x4 pinout, it simplifies integration between host controllers or backplanes and drive assemblies. The 55 cm length offers flexibility for routing in dense server layouts without excessive slack.

Подходит для

• Подключение контроллеров или плат расширения к корзинам накопителей

• Использование в компактных серверных и стоечных решениях с ограниченным местом
• Организация соединений для RAID-карт и модулей хранения данных

Key specifications

• Connector A: MCIO x8 internal connector
• Connector B: 2 × SlimSAS LP x4 internal connectors
• Supported protocols: SAS and SATA multi-lane links
• Length: 55 cm
• Form factor: internal, low-profile cable for server chassis
• Cable type: breakout (one-to-two) multi-lane assembly

How to use

Install the cable by seating the MCIO x8 connector into the host controller or backplane MCIO port and attaching the two SlimSAS LP x4 connectors to the target drive bays, RAID card ports or storage modules. Ensure connectors are fully inserted and latched as required by the chassis or card design, and route the cable to avoid sharp bends and interference with cooling airflow or moving components. Verify link status and drive visibility in system firmware or operating system after powering on.

Usage recommendations

For reliable operation, maintain gentle bend radii and avoid compressing the cable. Use the 55 cm length to route around hot components and secure the cable with existing cable management points. Confirm compatibility of SlimSAS LP pinouts with attached devices and ensure firmware or controller settings match the intended multi-lane SAS/SATA configuration.
