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

GLOBAL:
   SIZE     AVAIL     RAW USED     %RAW USED 
   163T      163T         203G          0.12 
POOLS:

'df -h' yields

Ten of the following osds in each of the three storage devices roughly corresponding to MAX AVAIL above.

Thread(s) per core:  1
NUMA cell(s):        2
Memory size:         133765852 KiB

3. Director node info.

One of this

CPU model:           x86_64
