Dual-port 10 Gbps InfiniBand adapter

This Mellanox MHEA28-XTC is a dual-port InfiniBand Host Channel Adapter rated at 10 Gbps per port. It connects to the host through a PCI Express 1.0a x8 interface and uses MicroGiGaCN copper connectors. The card suits servers, blade systems or storage platforms that need an InfiniBand fabric link.

Check PCIe slot width and generation

Verify that the target system has a free PCI Express x8 or wider slot compatible with the 1.0a specification. Confirm the chassis can accommodate a standard-height bracket and that the operating system or hypervisor includes driver support for InfiniHost III Ex hardware. Ensure the InfiniBand fabric you are joining runs at single data rate to match the 10 Gbps ports.

Fits x8 slots and frees CPU cycles

The adapter plugs directly into any PCI Express x8 or larger slot without extra risers or brackets. On-board RDMA and hardware transport offload move data between memory regions without CPU intervention, leaving processor cores free for application work. Two MicroGiGaCN ports provide redundant or aggregated fabric links using copper cables, while an optional media adapter module can extend reach over fibre up to 300 m.

Questions about this item

Does the card ship with MicroGiGaCN cables or must they be purchased separately?

The adapter includes two 4X MicroGiGaCN copper connectors; cables are not supplied and must be sourced separately.

How do I choose between the 10Gbps SDR and 20Gbps DDR versions of this adapter?

Select the SDR model for 10Gbps dual-port links or the DDR model for 20Gbps dual-port links; both share the same PCI Express x8 form factor.

What throughput can I expect from the 10Gbps rating when the card is installed in a PCI Express 1.0a x8 slot?

The x8 Gen 1.0a interface provides ample bandwidth for dual 10Gbps InfiniBand ports, so the card can sustain its rated 10Gbps per port in a real server.
