HI Everyone,

I have a super micro server sponsored to me by my company for educational purposes as we recently moved our corporate environment to the cloud. I have 11x 3TB physical drives setup with redundancy as one 28TB raid6 array.

I attempted to install proxmox on this by just following through the basic installation without creating anything manually. When I get into proxmox after installation it manually created 100 GB drive where iso's can be loaded too and the rest i can use for vms and whatever else I wanna do. this worked fine for a while until I re-installed the entire system then things started to go wrong. I cant even do a fresh install of proxmox to a different ip. If i set it up to the same IP i initially used then I cant use novnc to connect to the vms I create and I dont know why. I know this bit of information is a tad bit irrelevant, but my question is as follows.

Can someone maybe advise me if using on 28TB raid 6 setup is bad? and if so what would be a better solution and how would I go about setting that up. any help please?
 
11 is a really strange number of disks.

Can you use your controller as HBA? If this is for educational purposes then you could try to install ZFS. But ZFS on hardware RAID is bad.

The usual recommendation is to use (multiple) Mirrors. This would maximize IOPS while your Raid6 maximizes space.
For educational purposes everything might work though...

Best regards
