Dual-port InfiniBand adapter with 20 Gbps links on a PCI Express x8 low-profile card

  • Speed20 Gbps
  • Connectors2 x MicroGiGaCN Infiniband
  • InterfacePCI-Express
  • Dual-port design doubles cluster bandwidth
  • 20 Gbps per port for high-throughput workloads
  • PCI Express x8 host interface for server integration
  • Low-profile form factor fits dense chassis
  • RoHS compliant for regulated environments

Dual-port 20 Gbps InfiniBand HCA

The Mellanox MHGA28-XTC is a low-profile InfiniHost III Ex host channel adapter that occupies a PCI Express x8 slot. It presents two MicroGiGaCN connectors each running at 20 Gbit/s double data rate. The card is RoHS compliant and ships new.

Suited for clusters needing dual SDR/DDR links

This adapter fits existing InfiniBand fabrics that operate at 10 or 20 Gbit/s per port and require a PCI Express x8 host interface. It is not for builders who need single-port adapters, higher-speed EDR or HDR links, or cards with QSFP or SFP+ cages instead of MicroGiGaCN connectors.

PCI Express x8 host interface

The card connects to the host through a PCI Express x8 slot, which is the single specification that determines whether it can be installed in the target server or workstation. Verify that the system provides an available x8 electrical slot before purchase.
