What are the benefits of implementing bladed architecture instead of traditional rack mount servers? (Select two.)
A. lower initial capital cost
B. shared memory architecture
C. more predictable MTBF
D. higher compute density
E. shared power and cooling
Correct Answer: DE
Explanation/Reference:
Explanation:
D: Blade servers allow more processing power in less space which simplifies cabling, storage, and maintenance. Blades are often used for grid computing. The advantage of blade servers is not only that one "cabinet" houses multiple servers that share power source and other components, but also from the consolidation of related resources, such as storage and networking equipment, into a smaller architecture than would be the case with a farm of regular servers.
E: A blade server most importantly reduces power consumption and improves power management. Consolidating power supplies into the blade chassis reduces the number of separate power supplies needed and also reduces the power requirements per server. Because individual server blades are stripped to bare minimum and do not have other features found in conventional servers such as keyboard, graphic cards, and others, that employ less devices that need to be powered. This reduces overall power consumption. One blade server with 16 server blades uses much less power than 16 individual full-size servers.
