Database servers of any flavor - heck no! They need as much horse power as they can get.

To be precise, you need a proper physical disk controller since ERP database access is both very chatty and disk intensive. Virtualization isn't ready to handle disk-intensive applications yet - but we're getting close (with iSCSI etc)

Deployment server - we tried that a few years ago in the early days of virtualization, it was a trainwreck. Physical is the way to go.
[/ QUOTE ]I totally disagree with this. The deployment server is just a Windows fileserver - if you build packages on virtual workstations, there is no reason necessary to keep the deployment server physical. Its not mission critical, and its a "development" server in the eyes of the auditors - so go ahead and virtualize it.

Terminal servers - PY no big deal, PD is acceptible as long as you don't expect to have as many users on that server as you can get on a physical box. Just multiple the number by .5

Whats a terminal server ?! JK !!! Actually, putting a citrix box on a virtualized platform is really not a good idea, because citrix is like a virtual platform for the end users. I'd say its pointless, like running a virtual machine inside of a virtual machine - you just end up with performance headaches. I'm not sure the original post asked about citrix/TSE boxes however...

Web Servers......<clip>

These work well under Virtualized server. Remember, the only "officially" supported virtual platform is Oracle VM for production - so be very careful about doing this.
I noted that Greg didn't talk about JDE App servers - but those also work excellent virtualized. Again, don't do it for production since Oracle VM is the only "official" virtualized platform for production servers. But both the web and the JDE App servers are mostly CPU or memory intensive - so work very well in a virtualized environment.

Fat clients - not an issue virtualizing them. Been there, done that for the last 3 years.

Actually, theres also VDI coming out now, so that option is being refined even more - but I agree with Gregg, fat clients always work well as virtualized machines.
