Explanation of Solution
Given: Consider the data center in the figure “6.30” supports both e-mail and video distribution among other applications. Both the e-mail and video contains 4 racks of servers each. All the racks lie below single tier-2 switch.
To find: Fraction of time that the e-mail and video application uses the 4th rack if both has independent usage.
Solution:
The probability to get the fraction of time that the e-mail and video application needs the 4th rack if both has independent usage is given below:
c.
Explanation of Solution
Given: Consider that the application can have a shortage of servers (for 0.001% of time).
To find:
Solution:
Consider that the 1st three racks are allotted for videos and the 4th rack is shared among both the video and e-mail...
