Supermicro CBL-SAST-1256-100 Serial Attached SCSI SAS cable 56 m Slimline X4 4x SATA

The Supermicro CBL-SAST-1256-100 Serial Attached SCSI (SAS) cable is a 56 cm high-speed interconnect designed to link a SAS host or controller with multiple SATA drives. One end uses a Slimline X4 style SAS connector while the other end breaks out into four SATA connectors, providing a compact solution for internal server drive connectivity. The cable supports typical SAS-to-SATA configurations used in rackmount and tower servers and is intended for reliable, point-to-point data paths in storage subsystems.

Advantages

This SAS-to-4xSATA cable offers a space-efficient form factor and a single-cable route for connecting up to four drives, reducing cable clutter inside server chassis. The Slimline X4 connector provides a stable mating interface while the SATA breakout enables direct attachment of standard SATA drives. The overall construction is intended to deliver consistent signal integrity for high-speed transfers and to fit common server layouts where short, robust internal cabling is required.

Suitable for

• Connecting a SAS controller to up to four SATA hard drives or SSDs in a server
• Internal cable routing in 1U–4U rackmount and tower servers
• Storage array or RAID backplane expansions requiring SAS-to-SATA breakout
• Maintenance or replacement of damaged internal SAS/SATA cabling in data centre equipment

Key specifications

• Cable type: Serial Attached SCSI (SAS) to SATA breakout
• Connector A: Slimline X4 style SAS connector
• Connector B: Four SATA data connectors
• Length: 56 cm
• Usage: Internal server/storage interconnect

How to use

Power down the server and follow proper electrostatic discharge precautions before handling internal components. Plug the Slimline X4 SAS connector into the matching SAS port on the controller or backplane, ensuring correct orientation and a secure seating. Route the cable to each drive bay and connect the SATA plugs to the drive data ports. Verify that drive power cables are connected separately and that there is no undue strain or sharp bends on the cable. After reassembly, power on the system and check controller BIOS/firmware or operating system storage utilities to confirm that all attached SATA drives are detected and functional.

Usage recommendations

Use this cable for short internal connections only; avoid using it in exposed external environments. Keep cable bends gentle and secure the cable to chassis tie points to prevent movement. Confirm compatibility of the server controller and drives with SAS-to-SATA connections and ensure firmware and drivers are up to date for optimal interoperability.
