40 Gbps Dual-Port Fibre Channel HCA

The Mellanox Voltaire HCA 700Ex2-Q is a 40 Gbps Fibre Channel host bus adapter with two MicroGiGaCN ports. It installs in a PCI Express 2.0 x4 slot and supports multi-mode optical fibre. The card is RoHS-5 compliant and ships new.

Enterprise storage and HPC clusters

This adapter suits environments that need dual-port 40 Gbps Fibre Channel connectivity over multi-mode fibre. It is not for buyers who require single-mode fibre reach, a different port count, or a host interface other than PCI Express 2.0 x4.

PCIe 2.0 x4 slot and multi-mode fibre

The card occupies one PCI Express 2.0 x4 expansion slot and connects to two multi-mode optical fibre links. It frees the system from lower-speed interconnects while drawing no additional power connectors beyond the slot.

Questions about this item

Does my server need a PCI Express 2.0 x4 slot for this card?

Yes, the host interface is PCI Express 2.0 x4, so an available x4 or larger slot is required.

Will the 40 Gbit/s ports negotiate down to 20 Gbit/s for older InfiniBand switches?

The HCA family supports 20–40 Gb/s InfiniBand fabrics, allowing negotiation with 20 Gbit/s equipment.

How can I confirm the 40 Gbit/s link is active after installation?

Check the port LEDs on the MicroGiGaCN connectors and verify 40 Gbit/s link status in the OS or switch management console.
