While you make a valid point about RAM and response times, which seems to be the point of the article, I struggle to see how this a valid from a Disk I/O viewpoint.
Have you completed testing to validate this using a typical storage design for an Enterprise?
a) Have you tested Exchange 2010 using SATA disk? FC disk is very expensive compared to DAS/JBOD/SATA which is supported by 2010 now. Unless you have CX/FC storage available, there are arguably more appropriate storage solutions for Exchange 2010 now.
b) Why use a user profile of just 100MB mailboxes? Exchange supports mailboxes of many GB now, mostly due to Enterprise data/retention demands.
If you repeated this testing using 2GB and 5GB mailboxes on SATA/SAS storage then this would validate running Exchange 2010 on vSphere for me.
thanks

Exchange 2010 Disk I/O on vSphere
In the first part of this series on Exchange 2010 on vSphere the focus was scale-up performance of a single Mailbox Server VM. The results showed performance was great across all points tested, ranging up to 8000 users. This article will take a look at disk I/O which is an important aspect of E...
