We just got in a test chassis of the 4 node in 4U fattwin setup with 10 spinning disks, 2x DC S3700s, 1 system disk, and dual E5 CPUs per node. The guys in our data center said the thing weighs about 260lbs and hangs out the back of the rack. :D Mark > > > ----- Mail original ----- > > De: "Robert van Leeuwen" <Robert.vanLeeuwen@xxxxxxxxxxxxx> > À: "Alexandre DERUMIER" <aderumier@xxxxxxxxx>, ceph-users@xxxxxxxxxxxxxx > Envoyé: Mercredi 15 Janvier 2014 14:36:32 > Objet: RE: servers advise (dell r515 or supermicro ....) > >> I would like to have this kind of configuration for each node: >> >> - 2U >> - 2,5inch drives >> os : 2 disk sas drive >> journal : 2 x ssd intel dc s3700 100GB >> osd : 10 or 12 x sas Seagate Savvio 10K.6 900GB > >> Another option could be to use supermicro server, >> they have some 2U - 16 disks chassis + one or two lsi jbod controller. >> But, I have had in past really bad experience with supermicro motherboard. >> (Mainly firmware bug, ipmi card bug,.....) >> Does someone have experience with supermicro, and give me advise for a good motherboard model? > > We are using Supermicro 2uTwin nodes. > These have 2 nodes in 2u with each 12 disks. > > We use X9DRT-HF+ mainboards, 2x Intel DC S3500 SSD and 10x 2.5" 1TB 7.2k HDD Seagate Constellation.2 > They have SAS2008 controllers on board which can be flashed to be a JBOD controller. > > For ceph we install the OS on the SSDs > Each SSD also gets 5 journals. > > We have been using these machine for over a year now for various purposes (including, a somewhat similar workload: Openstack Swift) and are happy up to now. > > You might want to look at the new recently announced 2uTwin pro nodes if you want to have 10Gb copper on board. > The above machines just have 2x 1Gb. > > I think all brands have their own quirks, the question is which one you are the most comfortable to live with. > (e.g. we have no support contracts with Supermicro and just have parts on stock) > > Cheers, > Robert van Leeuwen > _______________________________________________ > 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 _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
