[GPU] Request for suggestions for OpenStack deployment

Hi, We are planning to buy some servers with GPU cards from DELL(R740/R750)/HPE/Supermicro with NVIDIA A100 40GB (GPU). I have the following questions: 1. What is the best ratio for Memory to GPU? or It doesn´t matter. 2. Anyone using A100? A100 has any known issues with OpenStack deployment? 3. If you have set up with similar server with GPU, could you share the server configuration? It will help us in deciding / identifying the components we have missed. Thanks in advance. Regards, ~ Jayachander.
