I need a new cluster strategy - cloud computing

[berkaybulut]

Hello, I am a long-time proxmox user.
We have purchased the following hardware for a new project and are about to launch a cloud computing platform at the entry stage. But I still haven't clarified the installation strategy and scenario.

Hardwares:
5 x Dell PowerEdge R630
1 x Dell Unity 600F
5 x Intel X520-DA2 10G Network Card
5 x FC Card

Our Requirements:
HA must be active.
It must have snapshot and clone support.
Shared Storage (for HA)

On the hardware and infrastructure side, we are fully prepared, but we still haven't clarified how we will proceed on the storage side.

Scenario 1:
Use thick LVM with iSCSI. (It does not support snapshot - a big disadvantage for us)

Scenario 2:
Ceph installation and using iSCSI for OSD disks. (Everything is perfect, but I have fears for the performance.)

Does anyone know any other scenarios?

Don't use ISCSI for OSD disks, this will trash the performance. Ceph needs fast local disks.

You could go with shared FC-LUNs and a cluster filesystem like OCFS2. This allows a shared file based storage in Proxmox which allows thin provisioning and snapshots.

As mentioned by @gurubert Ceph is not meant to work with external storage, its designed for local disks.
Given your infrastructure investment and your requirements, you've backed yourself into the only solution possible - OCFS2 formatted luns with QCOW2 as VM storage.
