Frequently Asked Questions

What is HDR100 InfiniBand?
HDR100 is a half-rate HDR InfiniBand speed delivering 100Gb/s per port — suitable for HPC clusters where full HDR (200Gb/s) is not required.
Can this operate as Ethernet only?
Yes — the ConnectX-6 supports Ethernet-only mode at 100GbE, making it usable in standard Ethernet data center environments without InfiniBand fabric.

The HPE P08256-001 MCX653106A-ECAT delivers dual-port 100Gb InfiniBand HDR100 and Ethernet in a PCIe 3.0 x16 adapter validated for HPE ProLiant — a versatile high-performance interconnect for HPC, AI/ML, and storage networking.
