I’m wondering what the best (cheap) option is to have as much storage as possible. I have two DL380 g7 servers with one running lemmy, npm, wireguard and busy getting nextcloud and jellyfin installed. The other one is to run a Proxmox cluster. Just for fun tbh. Amd if needed spare parts. I only have a few tb of storage. Problem is that these have a 2.5 inch harddrive. So expensive drives. Is it a good idea to just buy more drives which will cost me more in the long run i guess… Or should i go for a dedicated storage server with 3.5 drives…
Get a dedicated NAS server with 3.5" drives for bulk storage. Used SAS drives on eBay are pretty cheap. Use iSCSI or NFS shares mounted to your bulk data directories for Nextcloud and Jellyfin. Buy some SSDs for local storage on the DL380 servers and use those as system disks for your VMs.
You could install Proxmox Backup Server on one of your nodes and backup the VM disks on SSD pool to the NAS and have a backup then.
