HP InfiniBand Cable - Quad SFF Pluggable - 7M Length - Copper

DDR (Double Data Rate) and QDR (Quad Data Rate) refer to different generations and speeds of InfiniBand technology. QDR offers significantly higher bandwidth than DDR. This cable supports both, connecting to ports configured for either protocol.

While the cable's physical connectors and basic signaling might be compatible with other InfiniBand QSFP ports, it is optimized for and best supported within HP's InfiniBand ecosystem. Compatibility with third-party hardware is not guaranteed and may require specific configuration or result in reduced performance.

The cable itself supports the rates of the InfiniBand protocols it's connected to. For QDR, this can be up to 40 Gbps (4 lanes x 10 Gbps per lane). For DDR, it can be up to 20 Gbps.

Gently blow compressed air across the connector port and the cable's plug. If dirt persists, use a lint-free wipe with a small amount of isopropyl alcohol, allowing it to dry completely before reconnecting.

Specific warranty information should be obtained from the point of purchase or HP's official product documentation, as it can vary by region and reseller.

No, this is a specialized InfiniBand cable and is not compatible with standard Ethernet ports or protocols.

Verify that both connected devices have compatible InfiniBand ports. Ensure the cable is securely seated in both QSFP ports. Check device drivers and network configuration. Try a different known-good InfiniBand cable to isolate the issue.

Inspect the cable for visible damage. Ensure connectors are clean and free from debris. Check for excessive bending or stress on the cable. Ensure the environment is free from strong electromagnetic interference.

Confirm that both devices and the intervening infrastructure support the same InfiniBand protocol speed (DDR/QDR). Ensure network configurations are optimized for high throughput. Check for bottlenecks on the connected devices or other network segments.
