ADAPTEC Microchip Technology 2280100-R Serial Attached SCSI (SAS) cable 0.8 m, mini‑SAS HD (SFF‑8643) to 4×1 SAS

ADAPTEC Microchip Technology 2280100-R is an internal mini‑SAS HD ×4 (SFF‑8643) to 4×1 SAS fan‑out cable with sideband signal support, designed to link SAS/SATA host adapters or RAID controllers to individual SAS drives or SAS/SATA backplanes in server and storage environments. At 0.8 m length and supporting up to 6 Gbit/s per link, the cable enables point‑to‑point high‑speed data transfer and is suitable for compact rack or chassis installations where a short, reliable connection is required.

Advantages

The cable provides a compact, factory‑terminated fan‑out solution that reduces the need for multiple separate connectors and adapters, simplifying cabling inside storage enclosures. With support for sideband signals (SFF‑8482) it preserves necessary control lines for drive and backplane compatibility. The straight mini‑SAS HD to 4×1 SAS configuration ensures predictable signal paths and consistent performance up to 6 Gbit/s, while the 0.8 m length balances flexibility and signal integrity in typical server layouts.

Suitable for

• Connecting SAS/SATA host bus adapters or RAID controllers to individual SAS drives
• Linking HBA or RAID adapter ports to SAS/SATA backplanes in server chassis
• Short‑reach internal cabling inside rack servers, storage enclosures, and JBODs
• Upgrading or replacing internal fan‑out connections in enterprise storage systems

Key specifications

• Cable type: internal fan‑out cable, mini‑SAS HD ×4 to 4×1 SAS
• Connector (host end): mini‑SAS HD (SFF‑8643), straight
• Connector (device end): four 1‑lane SAS connectors (SFF‑8482 compatible sideband), straight
• Length: 0.8 m
• Rated data speed: up to 6 Gbit/s per lane
• Compatibility: SAS and SATA drives and backplanes when used with compatible host adapters and controllers
• Color: multicolour/white jacket

How to use

Power down the system before making internal cable connections. Insert the mini‑SAS HD (SFF‑8643) connector into the matching port on the host adapter or RAID controller until it seats securely. Route the fan‑out cable to the drive bay or backplane and connect each 1‑lane SAS plug to the corresponding drive or backplane port, ensuring correct orientation of the keyed connectors. Secure any cable routing to avoid undue strain and verify that sideband connections are aligned where required by the target backplane or drive. After connections are secured, power the system and confirm device detection in the controller firmware or operating system.

Usage recommendations

Use the cable for short internal runs within the chassis to maintain signal integrity; avoid tight bends near the connectors and keep the cable away from high‑power or high‑EMI components. Confirm compatibility with the host adapter and backplane documentation before deployment, and replace the cable if connectors show signs of wear or damage.
