New Installation

[mountainview]

Hi,

I have a few Servers that are currently running KVM VM's and another purely Plesk Server on bare metal, I want to consolidate the 3 machines into
1 Proxmox cluster
The machines have 128 GB of RAM and around 120 cores each with 4 SSD's in each machine.
Each machine has a MegaRAId controller that I think should just present the SSD's directly to Proxmox ?
Each machine has 6 Ethernet ports but all are 1Gbe I could upgrade to 10Gbe but don't really want to.

I would like to use some kind of shared storage or so that if one machine goes down the others pick up, all data could be stored for all machines on one server so the amount of Data is small backups can be made to cheaper slower storage.

the number of VM's will be around 11 initially and I was going to use v-Protect which I have downloaded and installed to look around and provides a good incremental rock solid backup system I can escape the cost by keeping it to under 11 machines and simply do backups for less demanding VM's (PBX etc) via cli or scripting.

I have some RAID storage I can use for backups and could build a SAN / NAS if required or even buy some SAN storage at 10Gbe in the same DataCentre fairly cheaply but would like to avoid that if possible.

My question is what would be a good structure to implement to achieve HA failover of machines and storage ?

If anyone can help I would be very happy, otherwise I'll be reading an awful lot to find out what I should do.

I have dowloaded proxmox 5 and created a two machine cluster some months ago to test and look around the system which was fairly straight forward.

Thanks

There is a list of available storage types on the wiki.

Proxmox VE has its own backup system.

Clusters can ensure high availability.

Hi yes I see Proxmox has its own system but I woudld like to do Snapshots every few minutes ie every 5 minutes, then ewvery hour then every day etc....
I can do this on a ZFS file system with some scripting and avoidv-Protect all together.
Proxmox does not do incremental backups or the last version 5 did not....
Should I install on a ZFS boot system I am tempted to do this as Proxmox now supports this.
Yes I will be using Clustering, when I had version 5 the cluster system was perfect, storage for HA required to be SAN / NAS type which is obvious but is it possible to have high speed duplication of storage across nodes ?
I just need some guides I am capable of building / configuring what ever is required.

The different shared storages distribute data in different ways across the nodes.

The official Proxmox VE Administration Guide is your best option.https://pve.proxmox.com/pve-docs/pve-admin-guide.html
