A build to run a ZFS storage for mirror server

More RAM usually equates to better performance because of the ARC that is in memory. With 3000 clients, there's bound to be files that are accessed multiple times and can be provided from the ARC instead of having to read it from disk again.

FreeNAS user since 2011 - - Currently Running, TrueNAS 12.0-U7 on one server at home and five at work.

This one was built in 2018, but I reused the name from a previous build. This is the 8th FreeNAS unit I have built for home. Eight systems in ten years... I made some mistakes along the way, learned some and I try to share some of those lessons learned experiences here in the forum. I have even put together some hardware just to test things out a time or two...
For a while I had three systems, all at once, at home but I am making some hardware changes right now and only one NAS is online.
The three pools in this one system represent the three NAS systems I had before the consolidation. For a home NAS, this chassis is huge, able to hold 48 data drives and two boot drives with a couple spaces internally for non-hot-swap drives...
