Suggestions how to best setup storage for new Proxmox server

Hi

 

I am currently running a Esxi server but want to try Proxmox, so I will reinstall everything. No need to save or convert any VMs.

I have some question how I best configure the storage for the new server. I want to have as much redundancy as possible, I already have a offsite backup.

 

This is what I currently have.
3 x 6 TB HDD
1 x 12 TB HDD
2 x 1 TB SSD
1 x 1 TB NVME SSD
1 x 256 GB SSD
1 x 128 GB SSD

 

What I have in mind so far is:

Fast storage: 2 x 1 TB SSD - Raid 1
Normal storage, buy one more 6 TB disk and configure all 4 as raid 10, if possible use the Nvme disk as cache?
Leave the 12 TB as a single disk for now and get one more later for raid 1.

 

Not sure what to use the small SSDs for, they are quite old so I don't really trust them.
One thought was to install proxmox itself on one of them but not really sure due to above.

 

Any suggestions?

It be tempted to make this a raid z1 in zfs or raid 5 for vm storage, etra space is nice, and performance will still be fine.

Id probably go raid z1 here too, and go raid 5 instead of raid 10. More space. The 12tb will have wasted space, but not too much you can do there.

"Id ake these 2 raid 1 for boot"
Great tip, will do this.

 

I was not sure how I could combine the 1 TB SSDs, I will consider using all of them in a single pool even if it might mean losing some performance for the Nvme disk.

I am unfamiliar with raid z1, will investigate this.

 

If combining all large disks in a single pool means losing 6 TB from the 12 TB disk I rather not do that and just get one more 6 TB disk instead.

 

Thanks for the help. 🙂

You could partition the 12tb drive, so 6tb of it is int he raid, and the other 6tb can be used for something else.

I will consider this. I assume I can swap out the 12 TB disk to a normal 6 TB drive in the raid if I want to free it up in the future?

Yup you could swap it out for a 6tb hdd later too.
