I'm am looking to replace an aging server and would like to hear some thoughts/comments on the "best" way to proceed.
We currently have a pretty simple setup with 1 server running Windows 2008 R2, which is used as our DNS, DHCP, and Domain Controller. In addition we run our client database software (for a dental practice) including print services and general file sharing.
I am in the market to replace this and considering all my options. I'm considering whether HA would be a good idea for something like this or if it's overkill for the $$. I like the idea of having failover as I am approx 4 hours away from this location if something were to go wrong. Of course this would require 2 phyiscal servers/hosts with shared storage (ie QNAP NAS etc.)
Another option would be to continue similar to how we're setup now, with a new Server 2016 server. If I go that route I would setup the local storage RAID 5 (with a hotspare?). From what I'm reading I would be able to then install 2 virtual machines using hyper-v so I can separate my roles/services etc. If I go this route I would opt for 24/7 4 hour support in the event anything were to wrong.
I'd like to hear comments on whether or not HA would be a viable/affordable option or if I should just go with the 4 hour support.
