Internal SAS Cable Supermicro CBL-SAST-1231-85 Slimline x8 to Slimline x8, MPN CBL-SAST-1231-85

Supermicro CBL-SAST-1231-85 is an internal SAS cable that connects Slimline x8 to Slimline x8 ports for direct point-to-point links between compatible storage devices and backplanes inside servers and storage enclosures. Designed for internal routing in high-density rack and tower systems, this cable supports SAS signalling over a compact Slimline x8 form factor to enable reliable data paths in constrained spaces.

Advantages

The cable provides a compact internal connection with full Slimline x8 compatibility, allowing straightforward integration into server chassis and storage arrays without using external adapters. Its internal design reduces clutter and shortens trace paths to lower latency between host controllers and target devices. The Slimline x8 connectors are keyed for secure mating, helping maintain consistent electrical contact for sustained performance in continuous server operation.

Suitable for

• Connecting Slimline x8 SAS backplanes to host HBA/RAID controllers inside servers
• Internal point-to-point links in rackmount and tower server chassis
• High-density storage enclosures where space and cable routing are constrained
• Server maintenance and upgrades that require direct SAS connections between modules

Key specifications

• Connector type: Slimline x8 to Slimline x8
• Connection: Internal point-to-point SAS link
• Compatibility: Designed for SAS storage devices and backplanes using Slimline x8 interfaces
• Form factor: Compact internal cable for use inside server and storage chassis

How to use

Identify the Slimline x8 ports on the host controller or backplane and align the keyed Slimline x8 connectors before insertion. Gently push the connector straight onto the socket until it seats fully; avoid excessive force or angled insertion. Route the cable inside the chassis to minimize sharp bends and keep it clear of cooling fans and moving parts. Reconfirm secure connections on both ends before powering the system and perform any required system BIOS or controller checks to verify device detection.

Usage recommendations

Use this internal Slimline x8 to Slimline x8 cable in environments that require short, direct SAS connections inside the chassis. Keep cable length appropriate for internal routing to maintain signal integrity, avoid tight bends, and ensure connectors are fully seated. Handle connectors by their housings and avoid pulling on the cable jacket to preserve terminations.
