Evolution of a data centre

Evolution of a data centre

Server age is coloured green - recent, to red - old. At each cycle a random number of servers over 36 months old is upgraded. This reflects the choice of servers to upgrade, and that not all servers take the same time to bring up to date. Even with a fixed budget the number updated will vary. The chosen servers are marked in blue - and then they will have an age of zero.
