MiniSAS‑HD cable FUJITSU ETJ4KM11‑L 1.1 m SFF‑8644 to SFF‑8644

MiniSAS‑HD cable FUJITSU ETJ4KM11‑L 1.1 m SFF‑8644 to SFF‑8644 is a high‑density SAS interconnect designed for short‑reach connections in storage and server environments. With SFF‑8644 connectors on both ends and a 1.1 metre length, this cable provides a direct link between SAS host controllers, RAID controllers, JBOD/JBOS enclosures and backplanes in rackmount and data centre systems where compact routing and reliable signal integrity are required.

Advantages

The cable offers a compact form factor with SFF‑8644 high‑density connectors that save space in dense server racks. Its 1.1 m length is suitable for direct internal or short external connections, reducing signal loss compared with longer runs. The design focuses on reliable SAS data transfer and compatibility with SAS controllers and enclosures that use MiniSAS‑HD interfaces, providing a straightforward, low‑latency physical connection for storage arrays.

Suitable for

• Connecting SAS host or RAID controllers to SAS backplanes and JBOD enclosures
• Short‑reach internal or external links in rackmount servers and storage arrays
• Upgrading or replacing MiniSAS‑HD interconnects in data centres and server rooms
• Applications requiring compact cabling and preserved signal integrity between SAS devices

Key specifications

• Connector type: SFF‑8644 on both ends
• Length: 1.1 metres
• Interface: MiniSAS‑HD (high‑density SAS)
• Cable category: short‑reach SAS interconnect suitable for direct device connections
• Use environment: storage systems, server racks and backplane connections

How to use

Power off equipment or follow hot‑swap and manufacturer guidelines before connecting. Align each SFF‑8644 connector with the corresponding MiniSAS‑HD receptacle on the controller and on the target enclosure or backplane, then insert until the connector seats securely. Route the cable to minimise bends and avoid sharp kinks; secure with cable ties or retention clips as appropriate to the rack or chassis. Verify link status via controller or enclosure indicators and perform any required device configuration in the host system.

Recommendations

Use the cable for direct, short connections where a 1.1 m length is sufficient; avoid extending with adapters that may degrade signal integrity. Maintain gentle bend radii, keep the cable clear of power cords and moving parts, and follow system vendor guidelines for SAS link setup and firmware compatibility.
