As I'm understanding now that's in this case (30 disks) 10Gbit Network is not a bottleneck! With other HW config ( + 5 OSD nodes = + 50 disks ) I'd get 3400 MB/s, and 3 clients can work on full bandwidth, yes? OK, let's try ! ! ! ! ! ! ! Perhaps, somebody has more suggestions for increasing performance: 1. NVMe journals, 2. btrfs over osd 3. ssd-based osds, 4. 15K hdds 5. RAID 10 on each OSD node ..... everybody - brainstorm!!! >John: >Your expected bandwidth (with size=2 replicas) will be (900MB/s * 3)/2 = >1300MB/s -- so I think you're actually doing pretty well with your >1367MB/s number. ************************************************************************************ This footnote confirms that this email message has been scanned by PineApp Mail-SeCure for the presence of malicious code, vandals & computer viruses. ************************************************************************************ ************************************************************************************ This footnote confirms that this email message has been scanned by PineApp Mail-SeCure for the presence of malicious code, vandals & computer viruses. ************************************************************************************ _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
