@MajorP93 I think there are multiple issue for memory . Pillow and acebmxer uses proxy , so the backup memory is handled differently
are you using XO from source or a xoa ? would you be ok to export a memory heap ?
Different use cases: Ceph is better with more hosts (at least 6 or 7 minimum) while XOSTOR is better between 3 to 7/8.
We might have better Ceph support in the future for large clusters.
