New Proxmox infrastructure on OVH

[Nick Carter]

Hello, my company is planning to move from VmWare 7 to Proxmox and we would like to buy dedicated server on OVH.
I have been studying a lot on this but i still have some confusion in mind.
We have some Vms, and we are hosting several website in the old infrastructure on them; to preserve business continuity, we had 3 vmware nodes distributed in 3 different geographical location (roubeaux, gravelines, strasburg).

My idea was to buy 3 advanced nodes (25 gbit/sec private network, latency between them attested to 10 ms averagely)+backup server on OVH to install proxmox in three different geographical location (all in France this time), and use their storage to create a single ceph distributed storage .

Am i crazy?

Do you suggest different solutions? I mean i could do it with 2 nodes and ZFS + backup server (with added qdevice functionality, so i can have 3 nodes). What do you think about it ?

Hi @Nick Carter , welcome to the forum!

I doubt there are many mental health professionals who visit proxmox forum, so I would not take anyone's diagnosis from here

Get 3 nodes in different locations and implement application level redundancy - do not create a bolt-on, latency-sensitive HA solution that is relying on external provider without SLA guarantees . If they were to provide you a full solution - sure, go for it. They have tested it and are responsible for it.

Use load-balancer, you can easily build an Nginx-like one for your Web infrastructure. Or if OVH provides one - use that. Frankly, if you are offloading your infrastructure to the Cloud, you want to use as many cloud-provided tools as you can.

Cheers

sadly they don't provide cloud solution proxmox-oriented.

Hi Nick

Ceph or any cluster should only ever operate in one datacentre. <1ms latency between each other.

The key to your question is what is your stated RTO/RPO goals? Would you be better hosting in 2 regions with 2 PBS instances which then synchronise backups between each other? If one fails then restore your VM's from a backup. Or does your application support active/passive & active/active configurations in which go with the suggestion above.

I've not yet tried to run PVE on OVHCloud. I've got Proxmox backup server running as a Virtual server image with attached storage. I added the repositories to a base Debian image and installed it manually. That works perfectly fine.

The concern I'd have is that a lot of cloud images can be configured with packages that would conflict with PVE so you may get weird issues.

EDIT: Hopefully not about to break a rule here.. OVHCloud work with Nutanix. They have full DR recovery cross datacenter that's fully automated. If you need a more managed solution they may be worth a look as well as they're fully supported on that platform.
