We have a 4-core physical server happily running along with Win2k3, IIS6, and SQL Server 2k5. Our service provider would like us to P2V the box to ESX. We are not opposed to it, but I've gotten really comfortable with assessing performance on the physical server and feel a bit squeamish about how the virtual replacement will be configured and perform. My quesitons:
The box is multi-slot, 4-core - what will the O/S 'think' it has for CPU? Will this make Windows want to re-register?
How will the performance compare? IIS and SQL love lots of cores and each is <10% on the physical box now. What will VMWare do with that?
Thanks in advance to all for your thoughts.
