Take a look at the following topic. It is not just relevant for TrueNAS but ZFS in generel. https://www.truenas.com/community/threads/whats-all-the-noise-about-hbas-and-why-cant-i-use-a-raid-controller.81931/
Be aware! The dell R730 most likely comes with a raid controller which is not suited for ZFS. You need a true HBA instead. Some raid controllers do let you set them up in JBOD mode but it still is not suited for ZFS as you need a proper HBA and or a raid controller where you can flash the firmware to IT mode.
For ZFS storage and many apps and more Truenas scale might be interesting to you.
I in fact run a AD domain controller *and *a rhel IDM controller. For me other then it is fun to play with, makes it a load more simple to manage the user accounts of my famalie. Also auto mounting network shares and setting a few policys for updates and security is great to from a central location. having SSO for many if my services also makes it more easy to use for the fam. The rhel IDM controller I use to manage a few user accounts. I also use it to manage the ssh keys and set sudo rules on all my servers.
Fully anonymouse and FREE P2P network great for torrenting and somewhat encouraged even.
I am already using this for publick services i have things jellyfin.publick.com domains. Which works fine for that usecase. What I am looking for here is to make SSL work properly for services that are part of the 2 local domains. where the 2 controllers are authoritative of those 2 domains.
you can still use sudo and all the other good stuff while only having one source of truth for identity.
I am aware that linux devices can join the AD domain. The reasons i setup up FreeIPA/IDM is the linux specific rules I can make. Like the Sudo rules for example. As far as i am aware you can not do this with a windows domain controller.
Yeah I love it. Also if you are stuck with outlook. Use Caldav synchronizer it is a add-on you can use with outlook to sync calendars with nextcloud.
