which type of graphic card support 40 VMs with HP DL 38 G9 server?

Dear Support Group of NVidia,

I am in charge of IT support in an educational institution in which we run 40 VMs that we need to install 3D MAX and Photoshop as well. We have a HP DL 380 G9 server on which we installed ESXi 6 on it.
I would be grateful if you could help with the type of graphic card to support 40 VMs that also be compatible with HP DL 38 G9 server and ESXi 6 besides be able to handle our virtual machines graphic needs.

Thank you in advance,

Best Regards
Ebrahim Kakavand
