all exchange version starting from 2007, uses high IOPs and this led to many organizations to go with Virtual setups.<br />

If you do not have budget constrains I would suggest you to start with VMware. Less head aches and easy management.

I have an Exchange server 2013, over the weekend I have installed Cumulative Update 6. After the installation I have noticed that the CPU is stuck at 100%. When I have checked the processes there is a process noderunner.exe using large amounts of memory and CPU.<br />
<br />
I am also experiencing intermittent connection to the Exchange server from Outlook. I do not know if this is related to the high CPU usage but if anyone has any ideas on how to troubleshoot and find a solution I appreciate your help.
