The External Mini SAS Cable HPE 407337-B21-RFB is a 1 meter external Mini SAS connection cable with 26-pin SFF-8088 connectors on both ends. Designed for use with HP storage arrays, host bus adapters and external enclosures, this cable provides a direct, point-to-point link for high-throughput data transfer. The 407337-B21-RFB model offers a standardized SFF-8088 interface to ensure compatibility with equipment that supports Mini SAS external connections and to maintain signal integrity in dense rack and storage deployments.

Advantages

This External Mini SAS cable supports high-speed data transfer and stable connectivity between compatible storage devices and controllers. The SFF-8088 26-pin connectors on both ends allow simple plug-and-play installation without additional adapters. The 1 m length balances reach and signal reliability for rack-mounted or adjacent chassis setups. Built to HP specifications, the cable is suitable for enterprise environments where consistent performance and connector durability matter.

Suitable for

• Connecting HP storage arrays to host bus adapters (HBAs)
• Linking external disk enclosures to servers or controllers
• High-density rack installations where short external SAS runs are needed
• Replacing or extending existing Mini SAS external connections in data centers

How to use

Ensure both devices to be connected are powered down or follow hot-swap procedures as recommended by the equipment manufacturer. Align the SFF-8088 26-pin connectors with the external Mini SAS ports on the host adapter and the enclosure or target device, then insert each end firmly until the connector latches if applicable. Power on equipment and verify that the host recognizes the external storage or enclosure. For multi-controller environments, connect according to your storage vendor’s recommended topology to maintain redundancy and performance.

Usage recommendations

Use this HPE 407337-B21-RFB cable for short external SAS runs within racks or between adjacent chassis to minimize signal loss. Avoid sharp bends and excessive pulling on the cable; maintain bend radius as specified by your hardware vendor. Replace cables showing visible wear, bent pins or intermittent connectivity to preserve data integrity.
