Cable ADAPTEC I-RA-HDMSAS-4SATA-SB 0.8 m — SFF-8643 to SFF-8448, 6 Gbit/s, grey

ADAPTEC I-RA-HDMSAS-4SATA-SB 0.8 m is a compact SAS to SATA fan-out cable that converts a single Mini-SAS HD (SFF-8643) connection into four SATA signal lines with sideband support (SFF-8448). With a length of 0.8 m and support for 6 Gbit/s per link, the cable is intended for short external or internal high-speed connections between SAS/SATA host adapters, controllers or backplanes and individual SATA drives in server and storage array environments.

Advantages

This cable provides a reliable, space-efficient way to connect a Mini-SAS HD port to multiple SATA devices while preserving sideband signals required by many backplanes and enclosures. The right-angle SFF-8448 end reduces strain and improves routing in dense chassis, and the 6 Gbit/s signaling supports legacy and mid-generation SATA performance. The grey jacket and robust connector terminations are designed for data centre and rack-mount installations where short, high-integrity links are needed.

Suitable for

• Connecting a SAS/SATA host adapter to SATA drives in a storage array
• Linking server controller cards to backplanes that require sideband signals
• Short point-to-point connections inside rack servers or small enclosures
• Upgrading or expanding existing SAN or DAS systems with SATA disks

Key specifications

• Connector A: Mini-SAS HD (SFF-8643)
• Connector B: SFF-8448 sideband fan-out to four SATA lines
• Length: 0.8 m
• Maximum per-link transfer rate: 6 Gbit/s
• Orientation: one end straight, one end right-angle to aid routing
• Cable colour: grey

How to use

Insert the SFF-8643 connector into the Mini-SAS HD port on the host adapter or controller, and route the right-angle SFF-8448 end to the target backplane or device ensuring proper alignment of the sideband contacts. Secure connectors to avoid movement during operation and verify that the connected SATA devices are recognised by the controller firmware or operating system. Use cable management to maintain clearance and prevent sharp bends that could impair signal integrity.

Usage recommendations

Use this 0.8 m ADAPTEC fan-out cable for short, high-speed internal or external connections in server and storage installations. Avoid excessive bending near the connectors, keep cable runs within recommended length for 6 Gbit/s operation, and ensure firmware and backplane compatibility with sideband signals before deployment.
