best practice for Proxmox Server with ISCSI SAN Storage

[parker0909]

Hi All,

We would like to setup the Proxmox cluster with SAN Storage(ISCSI), but i found alot reference in internet the iscsi not support LVM-Thin. it meaning we unable to create the virtual machine with Thin provisioning. May i know some best practice if we world like to setup three node proxmox cluster with SAN Storage? Thank you.

Sad, but true.

use LVM, best with multipath if your storage supports it. Best to have HA inside your storage box.

There are other options available that are natively supported in Proxmox. Each one comes with its own advantages and disadvantages.
It all depends on your needs and the type of SAN you have.

The primary starting point is here: https://pve.proxmox.com/wiki/Storage

There is no information on that page that will solve OPs problem.

@LnxBil I find that most people prefer to stay within the officially supported solution, especially for production. The table of PVE supported storage that lists features/functionality is the starting point to chose the direction. Once that's decided upon then best practices can be discussed.
Otherwise, without knowing what is important for OP (snapshots, automation, management complexity, replication, HA, security, etc.) the question is too ambiguous.

But the OP is already talking about a SAN, there is only iSCSI and FC for a "real" SAN (something that can be bought straight from a big company like HP, Dell/EMC, IBM, etc.) and the support of those is still very slim and unfortunately not on-par with the integration that exists on e.g. VMware. Therefore, LVM is the only supported option.

I don't know about he customers with your all-NVMe storage appliances, but all of our customers have at least one fully-ha SAN storage (2HE) till multiple racks full of big 3PARs.
