Hi ceph-users, Most of our servers have 24 hdds plus 4 ssds. Any experience how these should be configured to get the best rgw performance?
We have two options: 1) All osds the same, with data on the hdd and block.db on a 40GB ssd partition 2) Two osd device types: hdd-only for the rgw data pool and ssd-only for bucket index pool But all of the bucket index data is in omap, right? And all of the omap is stored in the rocks db, right? After reading the recent threads about bluefs slow_used_bytes, I had the thought that as long as we have a large enough block.db, then slow_used_bytes will be 0 and all of the bucket indexes will be on ssd-only, regardless of option (1) or (2) above. Any thoughts? Thanks! Dan _______________________________________________ ceph-users mailing list ceph-users@lists.ceph.com http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
