Do you think 4GB RAM for two OSD's is low, even with 1 OSD and 
4GB memory i encounter OOM during recovery.

This is just a test setup to try with ceph.

I am planning to use ceph in 36 drive system with Xeon e5v2 proc, 32 
GB RAM, 10Gb nic.

So, i am trying to optimize on memory usage on test setup which can be 
latter used if using ceph.

For bluestore setups by default 1 OSD need 4GB RAM, actually ~5-6GB for 
recovery purposes.

For 36OSD's you'll need 256GB RAM.
