Sounds like you are looking at vSphere ESX/ESXi and not VMware Server (long gone) or Workstation (runs on top of Windows or Linux). Given that you said servers and not server, I take that to mean a cluster of ESXi servers, which are typically managed by a vCenter Server (can be a virtual appliance, virtual machine, or physical machine).

Your next step would be to point the vSphere Client at the management IP (it is displayed on the command line screen) of the ESXi server.

Drop me a PM (or a DM on twitter @d_glynn), and I'll get on the phone with you, I play with this VMware stuff all the time
