I'm incredulous, have come across an environment where there are 4 CAS servers in the same AD Site.....for only 600 users! There is one MBX server and one HUB server All roles are split...so each role with it's own VM - resulting in a server footprint of 6 servers. No HA! No DAG! "The VMware guy told me we had to split the roles on one machine each for better performance" 3 of the CAS servers had been added to a CAS Array....a year after the MBX DBs were created... (the same idea is true for AD...each office of max 10 users has it's own AD Site and own DC...) Does anyone have the words to express this nonsense - ? I have writers block trying to sum it up :)

Yes the VMware tail is always wagging the Exchange dog it seems... I forgot to add they were attempting to run a product called 'Neverfail' for SAN replication and Exchange HA....couldn't get it to work. Hopefully they'll actually read my report that tells them simple is usually the way forward unless there's a reason to justify it. Let Exchange do it's job and stop messing around with third party items Exchange isn't even aware of (Vmotion etc) :) I see a consolidation of servers.... to 2x multi-role server/DAG/2 KEMP LM2600...consolidation of AD Sites and DCs...
