I am about to configure a NAS that’s suppose to supply the storage for 3 virtualization servers. And I need some advise regarding which base-system to chose. The NAS has good processors, sufficiently RAM, good disks and 10G connections between the servers… So I am mostly looking for general recommendations.
I was either thinking about a system primarily based on Ceph (RBD) or a system primarily based on some iSCSI variant. And I am leaning toward the Ceph (RBD) based system for 2 reasons: The development is more active and the full snapshots support. On the other hand iSCSI is a very well-tested technology (absolutely no gambles) and with ZFS over iSCSI I would also have full snapshots support.
The 3 virtualization servers will of course run Proxmox VE…
Do any of you have experiences/recommendations related to the differences between Ceph (RBD) and iSCSI?
Best regards
Jacob Tranholm
