SAS Cable BlueOptics 01DC679-BL 3m MiniSAS-HD SFF-8644

The BlueOptics 01DC679-BL is a 3m MiniSAS-HD (SFF-8644) to MiniSAS-HD (SFF-8644) SAS twinax cable designed for high-speed data transfer in server and storage environments. With a lightweight construction weighing approximately 160 g, this cable provides a compact, space-saving connection for racks and adjacent rack systems, supporting SAS devices such as hard drives, controllers and storage area network hardware.

Advantages

This MiniSAS-HD cable supports high data transmission rates up to 12 Gb/s when used with compatible SAS protocols and hardware. The compact MiniSAS-HD connector reduces space requirements in dense storage systems while offering low latency and low power consumption. Passive twinax construction keeps the design simple and reliable, minimizing failure points and enabling straightforward, quick installation in data center environments.

Suitable for

• Connecting SAS storage devices (HDD/SSD) to controllers or expanders
• Inter-rack and intra-rack connections in server rooms and data centers
• Short-distance high-bandwidth links for storage arrays and SAN equipment

Key specifications

• Cable length: 3 meters
• Connector type: MiniSAS-HD (SFF-8644) to MiniSAS-HD (SFF-8644)
• Transmission type: Twinax copper (passive)
• Maximum supported transfer rate: up to 12 Gb/s (with compatible SAS protocol and hardware)
• Typical use case: short-range rack interconnects and server/storage links
• Approximate weight: 160 g

How to use

Connect each SFF-8644 MiniSAS-HD connector to the corresponding MiniSAS-HD port on your storage controller, HBA, expander or target device. Ensure that connected devices support the SAS protocol and the expected link speed. Route the cable within rack-mounted systems to avoid sharp bends and mechanical stress; secure it with appropriate cable management to maintain signal integrity and accessibility. Power on and verify link negotiation and data transfer rates via your host controller or device management interface.

Recommendations

For reliable operation, use this passive MiniSAS-HD cable for short-distance connections inside racks or between adjacent racks. Avoid excessive bending near the connector heads and keep the cable away from sources of strong electromagnetic interference. Verify compatibility with your hardware's SFF-8644 interface and SAS speed settings before deployment.
