Walter and Many Cryogenic Sleep Pods (spoilers)

we know it is carrying 2000 colonists in hypersleep.

Looks like Sections of 30, Two Levels of 15 Cryo-Pods each section and there are Sections each side of the Wall.

I can make out at least 6 Sections on the Right of Walter so thats 6 X 30 =180 and the same must be on the other side for 360 Colonist but indeed they may be all in this area of there may be a number of Cryo-sleep Rooms, separated depending on maybe relation to what duty they perform.
