Somewhat of a misnomer. Yes, ZFS likes RAM, and yes it’ll use a lot if you let it. So the moar the better, obviously. But to suggest anything under 8GB is unworkable is a bit in the dramatic side. You may not get optimal performance in all cases but the system will function well enough to saturate a Gbps LAN and honestly if your budget is $600 with some found rust I doubt OP’s requirements are to stream several full bitrate 4K videos simultaneously.
I’m installing a new TrueNAS Core server with 8 bays. I have 6 disks of rust for the ZFS pool (3 2-disk mirror vdevs), 1 SSD for the OS, and 1 leftover SSD which long-term I intend to use as L2ARC.
My question is, for migrating my existing data (about 10TB) across the LAN (coming from a RAIDZ2 array), will it be much benefit to temporarily use that spare SSD as a SLOG? AFAIK SLOG is only useful for synchronous writes and since the new server won’t yet be in production there won’t be any contention for iops.
And does the answer change if I decide to use zfs send vs eg rsync?
“I understand sir, and I’m sorry to hear your WiFi is slow, I can absolutely help you with that. To get started, I’ll need your ticket number, 4-digit access PIN, and most recent math test.
Oh, I see here you earned a ‘C’, that only entitles you to 200Kbps down. If you are interested in our 1Mbps service we need proof of a ‘B’ - or if you would like to submit an ‘A’ we can offer our gold-tier 500Mbps service, and if you would like to take advantage of that offer during this marking period I can add in complementary 5ms ping SLA as well. Also your mother has told you three times to take the trash out, Anthony.”

Piggyback: anyone using LTO for backup/archival in their homelab?
Email and DNS. I have self-hosted both and I have no regrets. What I ALSO have is zero desire to do so again in the future.
Just bought some rack gear and I’ve been monitoring with the Kill A Watt - it’s not nearly as bad as folks make it out to be. My old tower based stack was maybe $20/mo whereas the new rack gear will be roughly $50/mo.
It’s certainly not nothing. But comparing price to value vs cloud hosts - setting aside topics like professional learning/development, hosting flexibility, privacy, and data sovereignty - it’s very reasonable (in my context and for my use cases).
That’s an underrated razor. Not the whole decision tree for me, but a huge part of it.
I did for years quite successfully. Ultimately blocklists did me in however - I don’t have the knowledge to resolve those timely and it became a headache I couldn’t tolerate at that time.
