How to know if my PC is compatible with VMware Player
Solution 1:
Any reasonable machine will run VMware Workstation or VMware Player. I have (had also) Workstation on Lenovo X1, X230, M73, M70s (all current right now), Lenovo T61 and machines before.
The item you need to know is if BIOS (UEFI) supports Hardware Virtualization and VT-d. You need these enabled to run 64-bit guests.
If a machine does not have Hardware Virtualization, then you can only run 32-bit guests.
You also need ample memory, minimally 16 GB.
Your machine is a Server and I did not see it on the Player list. See if you can find the Hardware Virtualization specs for it.
Solution 2:
Anything that can run (any version of) ESXi can run VMWare Player.
The requirements for VMWare Player are a subset of ESXi.
So your Proliant server is fine for that.
But I hope you realize that VMWare Player is an application on top of a normal Operating System. You will have to install Windows or Linux on that Proliant first.
