We are currently deploying Ethernet and hope to upgrade to an IB architecture in the future. Can we purchase this network card for our current Ethernet deployment and future upgrade?

Yes, you can. This card is a VPI card, supporting both Infiniband and Ethernet. You can switch between the two modes using the command mlxconfig –d mlx5_x s LINK_TYPE_P1=1 (or 2).

Does HCA refer to the InfiniBand adapter?

Yes, the InfiniBand adapter is also known as the Host Channel Adapter (HCA).

Connect X-6 card LED not turning on and ports are down always.

As far as triage of this issue goes, we recommend the following: Restart the OFED driver - /etc/init.d/openibd restart. Restart MFT - mst restart. Cold boot/power cycle the system. Ensure that a subnet manager is running - the subnet manager is required for Infiniband connections to establish. See if the problem persists. If so: Reseat the adapter, or try using the adapter in a different PCIe slot. Attempt use of a known-good adapter in this system.

Difference between ConnectX-6 DX and ConnectX-6 VPI cards.

ConnectX-6 VPI models do not have the same offload capabilities as the ConnectX-6 Dx. VPI models have the capability to change the port-type to Ethernet or Infiniband.

Can connectX-6 VPI Adapter Card accept QSFP28 transceivers?

Yes, ConnectX-6 VPI adapter supported PAM4 and NRZ.So,the QSFP28 transceivers can be used on QSFP56 ports.

Questions & Answers

Ask a Question

Does the IB card in Ethernet mode support RDMA?

Yes, it supports Ethernet RDMA, specifically RoCE (RDMA over Converged Ethernet). For large-scale networking, the NVIDIA Spectrum-X solution is recommended.

Is there a distinction between simplex and duplex for IB network cards?

They are all duplexes. The terms simplex or duplex are merely conceptual for current devices, as the physical channels for sending and receiving have already been separated.

Can a server allow the use of two types of cards (encrypted and non-encrypted) together?

Yes.
