1. Storage.

Three of these storage devices

CPU model:           x86_64
CPU(s):              8
CPU socket(s):       1
Core(s) per socket:  8
Thread(s) per core:  1
NUMA cell(s):        1
Memory size:         66656984 KiB

'ceph df' gives

'df -h' yields

Ten of the following osds in each of the three storage devices roughly corresponding to MAX AVAIL above. That is, a total of thirty of these.
