>> SATA: Micron 5100-5200-5300, Seagate Nytro 1351/1551 (don't forget to disable their cache with hdparm -W 0) We didn’t find a measurable difference doing this on 5100s, ymmv. Depending on your use-case, CRUSH rules (EC vs R), etc. sub-DWPD models may be fine for OSDs, but I suggest higher durability for mon DBs. I thought this list was dead and we were using the ceph.io list now? _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
