HPE 716189-B21 SAS External Cable

Overview

The HPE 716189-B21 is a 3.3-foot external SAS cable designed to bridge the gap between older SFF-8088 interfaces and newer SFF-8644 connections. This cable is essential for integrating modern SAS storage arrays or controllers with legacy SAS expanders or backplanes, ensuring data continuity and system compatibility in environments where mixed SAS generations are present. Its construction supports high-speed data transfer required for demanding storage applications.

Compatibility

This cable is engineered for use with systems requiring an external SAS connection. It features a 26-pin 4x Shielded Mini MultiLane SAS (SFF-8088) male connector on one end, compatible with external SAS host bus adapters or RAID controllers that utilize this interface. The other end terminates in a 4x HD Mini-SAS (SFF-8644) male connector, designed for connection to external SAS enclosures, disk shelves, or other storage devices equipped with the SFF-8644 port. Verify your specific server, storage array, or controller documentation for SFF-8088 and SFF-8644 port compatibility.

Installation Notes

Ensure both the SFF-8088 and SFF-8644 connectors are fully seated in their respective ports to establish a stable connection. The cable's shielding helps mitigate electromagnetic interference, crucial for maintaining data integrity in dense server rack environments. Avoid sharp bends or excessive tension on the cable to prevent damage to the conductors or connectors.
