9. Moore's law is the observation that the number of transistors in a
dense integrated circuit doubles approximately every two years.

17. Redundancy
Redundancy In engineering is the duplication of critical
components or functions of a system with the intention of
increasing reliability of the system.
27. Reliability
According to (Institute of Electrical and Electronics Engineers)
Reliability is defined as the ability of a system or
component to perform its required functions under
stated conditions for a specified period of time

37. Fault tolerance is the ability of a system
to continue performing its intended
functions in presence of faults.

39. Estimating power demand is the
biggest challenge for data centers.

40. AFCOM segments data center density into four
categories:
1. Low Density (up to 4 kW per rack)
2. Medium Density(5 kW to 8 kW)
3. High Density(8 kW to 15 kW)
4. Extreme Density(more than 16 kW per rack average)

41. Generally, data centers operate with about 50%
low density cabinets
35% medium
15% high density.
Estimating power demand
Demand Per Rack = 0.5x 4kW + 0.35x 6.5kW + 0.15x12kW
= 2kW + 2.275kW + 1.8kW
= 6.075kW

42. average power draw per cabinet
1) "Ten years ago, was probably 700 to 800 watts “
2) "Five years ago, it was 1.5 kW”
3) “Now, 3 kW”
4) “we'll see 5 or 6 kilowatt average power draw in five years”
said Jason Black, VP of data center services at Cosentry.
