Hi, I'm running dc p4610 6TB (nvme), no performance problem. not sure what is the difference with d3-s4610. ----- Mail original ----- De: "Kai Wembacher" <kai.wembacher@xxxxxxxxxxxxx> À: "ceph-users" <ceph-users@xxxxxxxxxxxxxx> Envoyé: Mardi 12 Mars 2019 09:13:44 Objet: Intel D3-S4610 performance Hi everyone, I have an Intel D3-S4610 SSD with 1.92 TB here for testing and get some pretty bad numbers, when running the fio benchmark suggested by Sébastien Han ( [ http://www.sebastien-han.fr/blog/2014/10/10/ceph-how-to-test-if-your-ssd-is-suitable-as-a-journal-device/ | http://www.sebastien-han.fr/blog/2014/10/10/ceph-how-to-test-if-your-ssd-is-suitable-as-a-journal-device/ ] ): Intel D3-S4610 1.92 TB --numjobs=1 write: IOPS=3860, BW=15.1MiB/s (15.8MB/s)(905MiB/60001msec) --numjobs=2 write: IOPS=7138, BW=27.9MiB/s (29.2MB/s)(1673MiB/60001msec) --numjobs=4 write: IOPS=12.5k, BW=48.7MiB/s (51.0MB/s)(2919MiB/60002msec) Compared to our current Samsung SM863 SSDs the Intel one is about 6x slower. Has someone here tested this SSD and can give me some values for comparison? Many thanks in advance, Kai _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
