Many 3,5'' SATA Drives for the storage (probably in a RAID config)
A small and cheap SSD for the journal

Many 2,5'' SATA Drives for the storage (RAID10 and/or mutliple OSDs)
Small MaxIOPS SSDs for each OSD journal

Many large SATA SSDs for the storage (prbably in a RAID5 config)
stec zeusram ssd drive for the journal
That's exactly what i thought too but then you need a seperate ceph /
rbd cluster for each type.
Which will result in a minimum of:
3x mon servers per type
4x osd servers per type
---
so you'll need a minimum of 12x osd systems and 9x mon systems.
