Product Identity

The Mellanox MHGS18-XTC is a single-port InfiniBand host bus adapter built for the PCI Express x8 slot. It carries a MicroGiGaCN connector and is designed for low-profile server chassis. The card delivers 20 Gbps double data rate throughput and includes RDMA, hardware transport and per-queue-pair QoS. RoHS compliance and a green-certified design complete the package.

Target Fit

This adapter suits clusters and storage fabrics that need a cost-effective 20 Gbps InfiniBand link on a single port. It works with existing PCI Express x8 infrastructure and low-profile form-factor requirements. Buyers who want more storage ports, a different connector type or higher link speeds should look at something else because this card provides exactly one MicroGiGaCN port at 20 Gbps.

Deciding Spec

The host interface is PCI Express x8 and the card height is low-profile; verify that your server has an available x8 slot and low-profile bracket clearance before ordering. The 20 Gbps double data rate and single MicroGiGaCN port are the fixed link characteristics that determine compatibility with your fabric. No other speed or port-count options exist on this model.

Questions about this item

Does my motherboard need a PCI Express x8 slot for the MHGS18-XTC?

Yes, the card uses a PCI Express x8 host interface and requires a compatible x8 or larger slot.

Will the single MicroGiGaCN port link with older 10 Gbps InfiniBand equipment?

The adapter runs at 20 Gbps DDR; it can connect to 10 Gbps SDR gear, but the link will operate at the lower 10 Gbps speed.

How do I verify the card is running at 20 Gbps after installation?

Check the link status in your InfiniBand management tools; a healthy DDR connection will report 20 Gbps per lane on the single 4X port.
