1) In a data centre, there are three types of servers: Web Servers (W), Database Servers (D), and Application Servers (A). The daily energy consumption (in kilowatt-hours) of each server type and their interaction with each other are represented by the following matrix:
W
D
A
W
0.4
0.4
0.3
D
0.2
0.3
0.3
A
0.3
0.2
0.3
Here, the entry of the matrix represents the proportion of energy consumed by server type due to the presence of one server type .
If the data centre contains 200 Web Servers, 500 Database Servers, and 300 Application Servers, calculate the total energy consumption contributed by each server type. How would you interpret the results in the context of optimizing energy efficiency in the data centre?
