Hi Experts,I am seeking for if there is achievable significant write performance improvements when separating WAL/DB in a ceph cluster with all SSD type OSD.I have a cluster with 40 SSD (PM1643 1.8 TB SSD Enterprise Samsung). I have 10 Storage node each with 4 OSD. I want to know that can I get better write IOPs and throughput if I add one NVMe OSD per node and separate WAL/DB on it?Is the result of this separation, meaningful performance improvement or not? My ceph cluster is block storage back-end of Openstack cinder in a public cloud service. Thanks in advance. _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
