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
