Hewlett Packard Enterprise Mini-SAS Cable, 2m Length, Black, Model: 716191-B21

Hewlett Packard Enterprise Mini‑SAS Cable

The Hewlett Packard Enterprise (HPE) Mini‑SAS Cable, 2 m Length, Black, Model: 716191‑B21 is a high‑performance external cable designed to connect servers, storage arrays, and other enterprise devices that use the Mini‑SAS High Density (HD) interface. This cable provides reliable data transfer between a 26‑pin Mini‑SAS HD connector on one end and a 36‑pin Mini‑SAS connector on the other, enabling seamless integration with HPE’s Smart Array controllers, D3600/D3700 chassis, and other compatible hardware.

Key Technical Specifications

• Model Number: 716191‑B21
• Length: 2 meters (approximately 6.56 feet)
• Color: Black (Negro)
• Connector Types:
  • Connector 1: Mini‑SAS HD (26‑pin, 4x Shielded)
  • Connector 2: Mini‑SAS (36‑pin, 4x)
• Application: External data transfer between servers and storage devices
• Compatibility: Designed for HPE D3600, D3700, H241 chassis; Smart Array 2040/10Gb; Smart Array P431; and other systems requiring Mini‑SAS HD to Mini‑SAS connectivity.

Design Features & Construction

The cable is engineered with a robust shielded twisted pair (STP) construction that minimizes electromagnetic interference (EMI) and crosstalk, ensuring data integrity at high speeds. The connectors are precision‑machined to meet the stringent tolerances required for Mini‑SAS HD interfaces, providing secure mating and reducing signal loss.

The black exterior not only offers a professional aesthetic but also helps in heat dissipation during prolonged operation. Each connector is marked with clear labeling to prevent misconnection, which could otherwise lead to data corruption or hardware damage.

Installation & Usage Guidelines

1. Preparation: Verify that both the source and destination devices support Mini‑SAS HD (26‑pin) and Mini‑SAS (36‑pin) connectors. Ensure that the cable is free from physical damage before installation.
2. Connection: Insert the Mini‑SAS HD end into the host device’s port, aligning the keying notch to avoid incorrect insertion. Connect the Mini‑SAS end to the target storage controller or array.
3. Securing: Use cable ties or Velcro straps to secure the cable along its length, preventing accidental disconnection and reducing strain on the connectors.
4. Testing: After installation, perform a link status check through the host operating system or management software. A successful link indicates proper alignment and signal integrity.

Performance Characteristics

The HPE Mini‑SAS Cable is engineered to support data rates up to 6 Gb/s per lane, which translates to a maximum aggregate throughput of 24 Gb/s across the four lanes. This performance aligns with the specifications of modern SAS controllers and ensures that high‑bandwidth workloads, such as database replication or virtual machine storage, run smoothly.

The cable’s shielding and twisted pair design also provide excellent resistance to external noise sources, which is critical in data center environments where multiple cables and power lines coexist. As a result, the cable delivers consistent performance even under heavy load conditions.

Maintenance & Longevity

To preserve optimal functionality:

• Avoid sharp bends or kinks; maintain a minimum bend radius of 10 cm (4 inches).
• Store the cable coiled loosely, not in tight loops.
• Inspect connectors periodically for signs of wear or corrosion. Replace if any damage is observed.

When properly cared for, the HPE Mini‑SAS Cable can maintain its performance characteristics for many years, making it a reliable component in long‑term infrastructure deployments.

Typical Use Cases

• Enterprise Storage Environments: Connecting HPE Smart Array controllers to external storage arrays or SAN switches.
• High‑Availability Clusters: Linking servers in a cluster that requires low‑latency, high‑throughput data paths.
• Data Migration Projects: Facilitating the transfer of large datasets between legacy systems and newer storage platforms.

Conclusion

The Hewlett Packard Enterprise Mini‑SAS Cable, Model 716191‑B21 is a meticulously engineered component that delivers reliable, high‑speed connectivity between servers and storage devices. Its robust construction, precise connector alignment, and shielding make it an essential element for any enterprise seeking to maintain data integrity and performance in demanding environments.
