Hi, Nice benchmark ! Maybe It could be great if you can add some fio benchmark. I'm interested to see random iops values, as I never be able to reach more than 8000iops with a rbd cluster. random read: (iops) fio --filename=/dev/[device] --direct=1 --rw=randread --bs=4k --size=1G --iodepth=100 --runtime=120 --group_reporting --name=file1 --ioengine=libaio random read: (iops) fio --filename=/dev/[device] --direct=1 --rw=randwrite --bs=4k --size=1G --iodepth=100 --runtime=120 --group_reporting --name=file1 --ioengine=libaio seq read: (bandwith) fio --filename=/dev/[device] --direct=1 --rw=read --bs=4M --size=1G --iodepth=100 --runtime=120 --group_reporting --name=file1 --ioengine=libaio seq write: (bandwith) fio --filename=/dev/[device] --direct=1 --rw=write --bs=4M --size=1G --iodepth=100 --runtime=120 --group_reporting --name=file1 --ioengine=libaio Regards, Alexandre ----- Mail original ----- De: "Sébastien Han" <han.sebastien@xxxxxxxxx> À: "ceph-devel" <ceph-devel@xxxxxxxxxxxxxxx> Envoyé: Lundi 27 Août 2012 22:47:06 Objet: Ceph benchmarks Hi community, For those of you who are interested, I performed several benchmarks of RADOS and RBD on different types of hardware and use case. You can find my results here: http://www.sebastien-han.fr/blog/2012/08/26/ceph-benchmarks/ Hope it helps :) Feel free to comment, critic... :) Cheers! -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html -- -- Alexandre D e rumier Ingénieur Systèmes et Réseaux Fixe : 03 20 68 88 85 Fax : 03 20 68 90 88 45 Bvd du Général Leclerc 59100 Roubaix 12 rue Marivaux 75002 Paris -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
