ESX is (in a word) the base OS. Really there is a console OS and the VM Kernel . The Console is Redhat (modified) but the overhead for it is bound to the first CPU and is very light. I would assume though the boxes we recommend are generally pretty large and we only do hand installs right now since there are only a few big boxes per environment.=20 Ron Oglesby Senior Technical Architect Microsoft MVP, Windows Server=20 =20 RapidApp Office 312.372.7188 Mobile 815.325.7618 email roglesby@xxxxxxxxxxxx =20 -----Original Message----- From: Tony Lyne [mailto:Tony.Lyne@xxxxxxxxxxxxxxxxxx]=20 Sent: Sunday, February 22, 2004 2:33 PM To: thin@xxxxxxxxxxxxx Subject: [THIN] Re: VMWare Server Sizing That's the exact kind of information I need.
