HPE 691971-B21 Concise Descriptor

Overview

The HPE 691971-B21 is a 0.5-meter cable designed to bridge connections between Mini SAS HD (SFF-8644) and standard Mini SAS (SFF-8088) interfaces. This cable is critical for integrating storage controllers with backplanes or disk enclosures in server and storage rack environments, ensuring reliable data transfer for high-density storage solutions.

Compatibility

This cable is specifically engineered for environments requiring the transition from Mini SAS HD (SFF-8644) connectors, commonly found on modern host bus adapters (HBAs) and RAID controllers, to the older, but still prevalent, Mini SAS (SFF-8088) connectors used in many server chassis and external storage arrays. It facilitates direct connections between these differing SAS connector types, ensuring compatibility within HPE ProLiant server configurations and other enterprise storage systems that utilize these specific SAS interfaces.

Installation Notes

Ensure connectors are fully seated to establish a stable link. The 0.5m length is optimized for direct-attached connections within a single rack unit or between adjacent servers, minimizing cable clutter and signal degradation. Verify that both the host controller and the target device support the SAS protocol and data rates intended for the connection.
