Frequently Asked Questions
- What is QDR InfiniBand?
- QDR (Quad Data Rate) is the 40Gb/s generation of InfiniBand — delivering 40Gb/s per port. It preceded FDR (56Gb/s), EDR (100Gb/s), and HDR (200Gb/s) and is considered a legacy InfiniBand generation, though still deployed in many HPC environments.
- Is this compatible with newer EDR or HDR InfiniBand switches?
- QDR InfiniBand is not directly compatible with EDR or HDR switches at full speed. Inter-generation connectivity requires gateways or adapters. For new deployments, EDR or HDR InfiniBand switches are recommended.
The Mellanox MIS5030Q-1SFC InfiniScale IS5030 delivers 36-port 40Gb/s QDR InfiniBand switching in a 1U form factor — a proven QDR InfiniBand fabric switch for HPC cluster interconnects and high-performance storage networking.
