Hi everybody, I'm looking for any hints on how to choose the hardware for small ceph cluster, roughly size of a 10-20TB. Primary purpose of this cluster is to have a centralized (from the client point of view), but fault tolerant storage for images served by webserver (i.e. mostly read IO).
I was thinking to buy a microcloud supermicro, two of these: http://www.supermicro.com/products/system/3U/5038/SYS-5038ML-H8TRF.cfm Single node has two disks, so I would put in one SSD on system an OSD journal and one 3TB SATA disk for data. My concern is, that this goes against recommendations mentioned in http://ceph.com/docs/master/start/hardware-recommendations/ i.e. putting the journal and the system on the same disk, but the system IO should be minimal in this setup, if I'm not mistaken. I would welcome any recommendation of how to best pull this off with the Ceph.
