32k vs. 8k page size: What is there beyond scalability?
I was looking a bit more into the new-ish 32k page size in the AD database and what it means in practise. My take that I came up is: If you don't have an urgent need or aren't doing a new Install, the actual advantage in practise isn't that big unless you have a very large directory. The risks are actual if you haven't checked a couple of things.
It's mostly about records that have a huge amount of multi-valued attributes but I don't see that in the directories I currently have access to. It's likely to happen in very huge directories with deep nested groups etc.
Would you agree with me or am I ignoring something obvious?
There are a couple of things you should check before even considerung the upgrade:
- No inplace upgraded Domain Controllers are OK
- Your AD Backup should support it (i.e. Veeam seems to require specific versions)
- You need to have backups since it's a one-way street, once the DB is converted to 32k page size it's not reversible.
And so far it also seems like this is the only new optional feature in Active Directory that actually requires a Domain and Forest Functional Level of 2025 - right?
