OT:Exchange good? (Was:Re: new hotness?)

[Bryan O'Neal]

Agreed, for larger companies ( I would even say over 500 users) the disk IO
can brutal.  Especially since it writes every message or change to the store
before scanning for discard.  Which is another reason why $500/year for off
site spam scanning is a must. Also remember it is handling much more then
just your mail.  That and you can split it up so the actual mail box stores
reside on faster disks with and mirrored to a more robust raid.  Then again
I have seen some very nice hybrid drives and well cached raid controllers
produce phenomenal results for very little coin.  The triad off some a
company that size is quite good.  Remember I did the bulk of my exchange
work for a company with less then 75 people and a monthly cash flow of
~$10Mill so the $250K/year IT budget they tossed me was nothing.  Especially
since I maintained a 300% ROI on had documented savings and value
generation.  I could not have done this if I had forced everyone onto
cyrus-imapd for all communications ;)

I know the 2 bugaboos for excahnge in requirements is Disk IO for large
companies, (not as much an issue in a small sub 1000 users
company) and ram. exchange up to 2003 is a 4gb of ram beastie.

im not sure about the mailbox recovery, but i know it can run on ESXi vm as
long as you have 2 cores and 4gb of ram to give it. we are getting ready to
convert ours to a Virtual machine ill let ppl know the results if they want.

Also excahgne 2007  is fully 64 bit and VM supported as well. we are hoping
to deploy that and migrate soon

but for mailbox recovery im not sure what has changed but i know alot has.
but it is better than it has been in the past (comparing 5.5 to
2k3 personally)
