- Power supply
- Cooling
What do datacenters - Fire prevention and detection
provide? - Equipment racks
- other facilities needed to host the installed
infrastructure components
What were early For large mainframe systems & peripheral systems like
datacenters designed for punch card readers and large tape units
- All end users were connected directly to the
mainframe leading to large cable bundles. With a
raised floor, the cables were installed in cable trays
why did early datacenters
underneath
have a raised floor?
- In these days there were watercooling systems and
(computer floor)
the water pipes for this were in the raised floor as well
Many datacenters still have raised floors
They had to be present in the computer room most of
the time because most equipment was installed there.
What were typical tasks
Typical tasks were:
for operators in
- Loading punch card decks
datacenters/computer
- Replacing paper in printers
rooms in the early days?
- Switching tapes in tape units
- Collecting printed paper

- Datacenters got equipped with standardized 19"
racks, installed in rows forming corridors between
them
What changed in the - More flexible air cooling (instead of water cooling)
datacenters when smaller - Sophisticated fire prevention, detection and
midrange x86 based extinguishing systems were installed
systems emerged? - lights-out datacenters were introduced; almost all
work on the servers could be done without touching
the physical equipment. During normal operation, no
people were needed inside the datacenter
- Sub Equipment Room (SER)
