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 ;) -----Original Message----- From: plug-discuss-bounces@lists.plug.phoenix.az.us [mailto:plug-discuss-bounces@lists.plug.phoenix.az.us] On Behalf Of Stephen Sent: Friday, February 20, 2009 11:21 AM To: Main PLUG discussion list Subject: Re: OT:Exchange good? (Was:Re: new hotness?) 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) On Fri, Feb 20, 2009 at 11:13 AM, Bob Elzer wrote: > Well I haven't used the latest exchange and it's been a while, so > maybe you can tell me if they worked around the issues I had with it. > > It requires it's own server.
