How to maximize NVME SSD

[wagabae]

Hello Experts,

Thank you in advance.

Any way you can suggest maximizing my unused NVME Disk?
I am planning to have it use the following for.
- Store a Backup Data
- and VM disk. (VM will be run on Hard Disk and if I need additional data, I am planning to get from the NVMe Disk.

any way that you can recommend that is much better?

Please guide me.

Thank you

Just out of curiousity, why store your vm on Hard Disk and not NVME? The VM would run a lot faster than on HDD. Backup does not need fast storage. And when you store more VMs on that HDD it would be a lot slower considering the low IOPs of HDD

+1. I run three Proxmox nodes (not in a cluster). One is my "production" machine running my public Wordpress sites, one is my testing machine that can be running anything at any given moment, and one is my backup machine running open media vault as one of my local back up destinations for my Synology NAS. All three machines use NVME drives (in a ZFS mirror arrangement) for the OS and for the VMs. My testing machine also has spinning drives just for storage of ISOs and such. My backup machine also has SATA SSDs for storage.

I know that ZFS supposedly will destroy consumer SSD and NVME drives, but that hasn't been my experience yet (over the last 18 months). I do however disable corosync, pve-ha-crm, and pve-ha-lrm on all my hosts.

noatime / atime=off definitely helps as well.

I hope not backups of the VMs/LXCs that also got virtual disks on that same NVMe SSD?

I was planning on storing the backups and the images of my VMs and Containers.

Is it that would be okay?

Never store your backups on the same disk as the VMs/LXCs you are backing up. Once that disk dies (and it will sooner or later) you not only lose your VMs/LXCs but also your backups at the same time.

Hi @Dunuin , thank you much for this input, this will help to learn more managing proxmox datacenter.
