Supermicro CBL-SAST-0703 SAS cable 0.23m

The Supermicro CBL-SAST-0703 is a 0.23m copper Serial Attached SCSI (SAS) cable with a MiniSAS HD SFF-8643 connector on one end and four SATA connectors on the other. Designed for internal server use, this compact cable supports high-speed data transfer between a MiniSAS HD host or controller and multiple SATA drives while helping maintain tidy cable routing and airflow inside chassis.

Advantages

The 0.23m length is suitable for short internal runs where space is limited, reducing excess cabling and improving airflow. The copper construction provides reliable signal integrity for SAS/SATA connections, and Supermicro certification ensures compatibility with Supermicro systems. The MiniSAS HD to 4×SATA breakout design enables connection of four SATA drives from a single SFF-8643 port.

Suitable for

• Connecting a MiniSAS HD (SFF-8643) port to up to four SATA drives
• Internal server and storage enclosure cabling in compact spaces
• SAS/SATA breakout applications where short cable length is required

Key specifications

• Brand: Supermicro
• Model / MPN: CBL-SAST-0703
• Type: MiniSAS HD (SFF-8643) to 4×SATA copper cable
• Length: 0.23 m

How to use

Power off the server and storage hardware before connecting. Insert the SFF-8643 MiniSAS HD connector into the host port or HBA, and attach the four SATA connectors to the target drives ensuring correct orientation. Route the cable to avoid blocking fans or airflow paths and secure it with cable ties if necessary. After connections are made, power on the system and verify drive detection in BIOS/RAID controller utility or operating system.

Recommendations

Use this short Supermicro breakout cable for internal, short-reach connections inside server chassis or storage enclosures. Avoid kinking the cable, maintain gentle bend radii, and keep the cable clear of moving parts and hot components to preserve signal integrity and device cooling.
