Hi Azure community,
we are trying to setup a HPC cluster with NVIDIA GPU DIRECT RDMA capabilities. For this we are planning to use https://learn.microsoft.com/en-us/azure/virtual-machines/nda100-v4-series
the documentation says it supports NVIDIA Mellanox HDR InfiniBand connection. But can anyone please confirm if they have soft roce support?
thanks.

Thanks for considering the query. One correction is, it will be RoCEv2 instead of Soft RocE, the Software emulation might not support NVIDIA GPU Direct RDMA. So if you can check and confirm if the ND A100 v4-series support RoCEv2 that will be very helpful.
