vmserver or esxi

[wjh]

I have a Blackberry server running on ancient hardware.  It has about 
100 users on it.  I'm thinking I will P to V it, rather than do a knife 
edge cutover.  Would you consider just using VMserver or would you use 
ESXi?  The new box will be a DL360 (single processor) with 15k scsi 
drives and 2 gigs of RAM.  It will do nothing but host the BB server.

Thanks for any input.
