SAS-kabel ADAPTEC Microchip Technology 2305500-R SlimSAS ×8 naar 2×2SFF-8639 U.2, 0,8 m, zwart

ADAPTEC Microchip Technology 2305500-R is an internal SlimSAS ×8 (SFF-8654) to dual SFF-8639 (U.2) 2×2SFF-8639 cable, designed for short internal connections in server and storage systems. At 0.8 m length and finished in black, the cable provides a direct attached connectivity path that supports SAS, SATA and NVMe tri-mode devices, enabling a single SlimSAS ×8 host interface to connect to two U.2 drives or backplane ports. It is intended for use with SAS controllers, RAID adapters and HBAs where a compact, reliable internal link is required.

Advantages

This SlimSAS ×8 to dual U.2 cable offers a compact, factory-terminated solution that reduces the need for adapter boards or complex cable routing inside chassis. Its tri-mode design ensures compatibility with SAS, SATA and NVMe storage devices through the same connection standard, simplifying hardware configurations. The 0.8 m length is suitable for typical internal server layouts, and the straight connectors on both ends provide predictable mating and alignment during installation.

Suitable for

• Connecting SAS controllers or RAID/HBA adapters to U.2 (SFF-8639) drives or backplanes inside servers
• Short internal linkages in rack and tower server storage bays
• Direct-attached storage setups that require NVMe, SATA or SAS device access through a SlimSAS ×8 interface

Key specifications

• Cable type: Internal SlimSAS ×8 (SFF-8654) to dual SFF-8639 (U.2)
• Supported protocols: SAS, SATA, NVMe (tri-mode)
• Connector orientation: Straight SlimSAS ×8 on host side; two straight SFF-8639 (U.2) on device side
• Length: 0.8 m
• Color: Black
• Application: Direct attached internal server/storage connectivity

How to use

Power down the system and follow standard electrostatic discharge (ESD) precautions before installation. Route the cable inside the chassis to avoid obstructing airflow or interfering with other components. Insert the SlimSAS ×8 (SFF-8654) connector into the compatible controller or adapter slot, then connect the two SFF-8639 (U.2) connectors to the U.2 drives or backplane ports, ensuring secure, firm seating of each connector. After connections are made, verify drive detection in the server firmware or operating system and restore power.

Recommendations

Use this cable for short internal connections only; avoid excessive bending and keep bend radius within manufacturer-recommended limits to maintain signal integrity. Ensure compatibility of the host controller and drives with tri-mode U.2 interfaces and confirm that firmware and drivers support NVMe or SAS modes as required.
