The solution uses CX7 adapters that can be configured as InfiniBand or Ethernet, as needed.
For InfiniBand deployments, a pair of Mellanox QM9700 IB NDR 400 Gbps switches (as shown in the following figure) are required for full HA, unless the customer HPC cluster has enough free ports for all the redundant connections for the different NG-Stor servers.

For Ethernet deployments, a pair of Mellanox SN3700 Ethernet 200 Gbps switches (shown in the following figure) are required for full HA, unless the customer HPC cluster has enough free ports for all the redundant connections for the different NG-Stor servers. There is also a 100 Gbps version of the switch, the SN3700C (not shown), and a 400 Gb/s version, the SN4700 (not shown).
