Adam,

We use different pools for volumes, images, and Nova ephemeral disks with our Openstack+Ceph deployment.  We don’t currently use different disk types, but there is no reason we couldn’t - and we do plan to do so in the future.

We also leverage a non-Ceph SSD solution that we already own for SSD-backed Cinder volumes in addition to our Ceph based Cinder volumes since Cinder lets you have multi-backend.

Has anyone deployed Ceph and accommodate different disk/performance requirements? I.e. Saving ephemeral storage and boot volumes on SSD and less important content such as object storage, glance images on SATA or something along those lines?

Just looking at it's realistic (or discover best practice) on using the same Ceph cluster for both use cases...
