We're preparing to migrate our single SBS 2011 box to "full" Exchange 2016. We don't like the SBS limitations nor interface. The environment is 35 active users, 75 mailboxes, and 400 GB of active Exchange data.
I'm being advised to buy at least two boxes, one for DC and one for Exchange. A consultant is saying that 3 boxes would be better, 2 for DC. He's also talking about 4 boxes, which would include a shadow server that would pick up if the primary Exchange server failed. This all sounds a bit excessive. We can use the old server as a backup DC, so I'll probably buy two new boxes.
Some people say that virtualizing Exchange is the way to go, for rapid recovery. I'm inclined to stay with bare metal and a RAID 10 box for Exchange -- (8) 1TB enterprise hard drives should do it. Is there any reason not to go for SSD (aside from price, which may be out of our budget)?
Our environment is 100% Mac so we'll be upgrading to standalone Outlook 2016. No one likes Word, Excel, etc 2016 for Mac -- these programs are sluggish and less stable than 2011.
Finally, we want to stick with Dell because we know the platform inside out. However, we can't find any email notifier that works with Dell servers for hardware failure notification. Is there anything out there below the Enterprise level?
All suggestions welcome.
