DC question

[Olliedawg]

Wanting to pick everybodys brains on this one - Is there any point in running more than 1 Domain Controller if I only have a single host server running VM's? To my knowledge the only reason you would run 2 / 3 DC's is if you have multiple hosts for redundancy.. although some threads i have read state otherwise & that it is always best practice to run 2 DC', even if you only have the 1 host. I'm guessing this is to take into account for corrupted DC's / VM corruption? Although I suppose this wouldn't matter too much if you have good backups?

Even with 1 host I'd run 2 DC's. Just in case one VM goes kaput you don't have any downtime

 

Ideally 2 hosts 2 DCs, but if for budget reasons this isn't possible then 1 host 2 DCs

2 on 1 host won’t help with hardware redundancy but will help if something happens to the guest operating system.

I think I will spin up another DC, even with backups it’s better to be safe than sorry I suppose!

 

We have 2 HP ProLiant DL380’s which I’m just about ready to retire which have been in service since 2015.. Consolidated a lot of stuff down & also have way less VM’s now after decluttering.

 

Got a Poweredge 760XS with a 7 year next business day warranty as a replacement.

Yea if some hardware goes kerput it makes no difference.. SLT are aware of the downtime possibility though so that’s that!
