Shared storage recommendations.

[Esben Viborg]

Hi

Atm. i am running a Proxmox cluster with 6 nodes. They are all configured to run the vms on each nodes own LVM-thin storage.
However i would like to move to a shared storage solution.
I have looked at ceph, however due to storage port limits in my current nodes, im not able to install extra disks in each node to run Ceph.

Performance is key. The solution has to run fairly fast.

Any recommendations?

A storage solution based on Omnios using ZFS over iSCSI is rock stable and gives very good performance given the ZFS pool is properly configured. A raid10 like setup gives the best iops for the sake of available storage. This in depth article is recommendable: https://calomel.org/zfs_raid_speed_capacity.html

Is there a way to have a HA configuration similar to that what some people built around FreeBSD with dual controllers on two boxes with a kind of failover ZFS?

If you have cash to spend (RSF-1): https://www.youtube.com/watch?v=JZ2PK-AXZ0A

Otherwise use UPS to guard your storage server and
Cheap: multiple nics using LACP
Less cheap: Configure multipath on proxmox to storage server preferable using LACP on each path

Oh, I'm familiar with the logo, so I already had at least a look at tit. Looks promising.

After googling a bit, I must say that there are now a few HA solutions. Good to see.
