[The following views only behalf of myself, not relate with Intel..] Looking forward for the performance data on Atom. Atom perform badly in Swift, but since Ceph is slightly efficient than Swift, it must be better. I have some concern about weather Atom can support such high throughput( you have 16 disks, assuming 50MB/s per disk, you would like to have 50*16 *2(include journal write)=1600MB/s ,together with corresponding network throughput, say 10GbE. The total IO throughput seems too high for Atom. Baidu (www.baidu.com) use Arm based storage node(not using ceph,but their own DFS), a node with a quad-core Arm together with 4 disks, and a 2U box can put up to 6 nodes, the 6 nodes share a 10Gb NIC. Although Atom is different with Arm, but you can take Baidu as a reference.
