We didn’t find a measurable difference doing this on 5100s, ymmv.
It depends on the controller...With chipset SATA and LSI 9200 HBA the difference is huge. I have some evidence here: https://yourcmc.ru/wiki/Ceph_performance#Server_SSDs
With some controllers it may be not the case. -- With best regards, Vitaliy Filippov _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
