Update on my #homelab: I received the R210 II and R420 a couple weeks ago and have been fiddling with them ever since, mostly on the R420.
iDRAC Enterprise is a fantastic tool and I've been loving Proxmox. This R420 is primarily to replace my current NAS (WD EX2100) so I have ZFS setup with 4x 3TB drives in a RaidZ2.
This is my first time purchasing used HGST drives but all seems well. I do have multiple backups though. My old NAS is a secondary local backup and Backblaze as the offsite.
