Hello, I have a single physical host running CloudStack. Primary storage is currently mounted as a NFS share. The underlying filesystem is XFS running on top of Linux Soft RAID-0. The underlying hardware consists of 2 SSD-NVMe drives.
The question is that, could I reach faster I/O on VMs if I would use Ceph adding 2 physical devices directly to the cluster and expose it via RBD? How much could it make the I/O faster? Thanks
