In that case there is no advantage of using a seperate cluster network. As it would only be beneficial when replication data between OSDs is on a seperate interface. Is the cluster heavily loaded? Do you have metrics on bandwith usage / switch port statistics? If you have many "discards" (and / or errors) this might impact the ping times as well. > The mgmt network is a 1 Gbps network, but this one shouldn't be used for > such pings among the OSDs ... I doubt Ceph will use the mgmt network, but not sure if 't doing a lookup on hostname which might use mgmt network in your case or if it's using configured IPs for ceph You can dump osd network info per OSD on the storage nodes themselves by this command: ceph daemon osd.$id dump_osd_network You would have to do that for every OSD and see which ones report "entries".
