SAS Cable QNAP CAB-SAS20M-8644 2m Black Metallic

The QNAP CAB-SAS20M-8644 2m Black Metallic is a SAS data cable with SFF-8644 connectors on both ends, designed for point-to-point connections between host controllers and storage enclosures. At 2 metres in length, this cable provides sufficient reach for typical rack-mounted and desktop configurations while maintaining signal integrity for high-speed SAS transfers. The metallic black finish improves mechanical resilience and assists with durable handling in professional IT environments.

Advantages

This SAS cable supports high-bandwidth serial-attached SCSI communication with stable connections at standard SAS data rates. Its dual SFF-8644 terminations ensure compatibility with modern SAS controllers and expanders, while the 2 m length balances flexibility and low signal loss. The metallic outer jacket and robust connector housings enhance physical durability and help reduce interference from external sources.

How to use

Power down devices or follow hot-swap procedures recommended by your storage system before connecting or disconnecting SAS cables, if applicable. Align each SFF-8644 connector with the corresponding port on the controller and storage enclosure, insert firmly until the connector seats, and secure any retention clips if present. Arrange the cable to avoid sharp bends and excess strain; use cable management in racks to maintain airflow and reduce mechanical stress.

Usage recommendations

For reliable operation, use this SAS cable within its recommended bend radius and avoid tight kinks or repeated flexing. Verify firmware and controller compatibility with SFF-8644 connections in mixed vendor environments. When deploying in rack systems, route cables to minimize electromagnetic interference and label both ends for easier maintenance.
