Hi there, I‘m rather new to napp-it and am looking to use several drives to maximize their potential. I was wondering if anyone can comment to see if this makes sense and apologies ahead of time if it’s not the right sub forum. My primary use case is for a large virtualized Nextcloud host, and iSCSI ESXi target for VMs at home for 5-8 users within a 40GBe (may upgrade to 100GBe) network. The ZFS pool will have the following resouces:
1) up to 24 cores from a Xeon 8176M Platinum
2) up to 256GB DDR4 RAM allocated
3) 3x Optane 905p 960GB U.2 drives
4) 2x Intel D4502 7.68TB QLC drives
5) 3x Samsung PM1733 15.36TB TLC drives
a) I’m looking to create 2 namespaces per 15.36TB drive (at 7.68TB each) so that it can match the 2x 7.68TB drives, giving me 8x 7.68TB to work with
b) should I overprovision each drive (7.68TB —> 6.4TB) and use RAIDz1 granting me 44.8TB usable vs. no overprovisioning and use RAIDz2 granting me 46.08TB usable?
c) with the Optane drives, I’m planning on using one for SLOG, and then mirroring 2 of them for special VDEV. Is this the best way to utilize the drives?
I might be missing something, but much appreciated in advance!
