SOLVED Lost in ZFS stuff

[Binary Buddha]

Anybody know of any ZFS RAIDZ calculators?

I'm planning on an upgrade and I'm trying to figure out how much RAM I would need at a minimum to follow the 1GB RAM per TB disk space rule.

My server case can fit 15 drives and I already have 5x 8TB drives running seperate from the boot drive and the cache drive. I'm trying to figure out how much ram I would likely need if I were to fill the other 10 bays with 12TB drives. Or even get them all up to 12TB.

I'm hoping that 64GB DDR3 ECC/non-ECC UDIMM would be sufficient. Else I'd have to drop a pretty penny and max out at 512GB DDR3 ECC LRDIMM. I'm using an Supermicro MBD-X9SRH-7F-O.

Yes, I've already googled it. But, I don't see any that options in the different types of RAIDZ stuff.

The general rule is outdated these days. FreeNAS requires a minimum of 8GB RAM with 16GB being recommended by the community. 64GB RAM will be plenty for the size of pool you have in mind.

No. It works fine in Chrome, Fire Fox, Internet Explorer and even Microsoft Edge.
If it isn't working for you, your browser or your firewall is not allowing it to work.

I retract my statement. Unbound took a shit

Domo.... What's the "Drive Cost" thing?

How much a drive costs to buy (in whatever currency you want to work in.)
