Question 2 In this task, you need to demonstrate the creation and usage of virtual machine using Debian OS. A pet store chains WonderPet has purchased a server with 10 hard disks (each hard disk has a storage size of 2 TB). The server is installed with Debian OS, and it has an operational life of 3 years. The requirements for the storage space are stated as follow: 4.5 TB is needed for the marketing department to store various marketing materials to promote the pet store. Redundancy is needed such that no data should be lost. 1 TB is needed for each store (total 7 stores) to store pet related materials. Redundancy is needed such that no data should be lost. A temporary storage space for all the staff for fast sharing of non-sensitive information It is estimated that this space will need 2000 GB in the first year, and it will increase 10% in the second year, and it will grow by 50% (from second year) in the third year. No redundancy is needed although performance is important Note that besides the Debian operating system, which is installed in a hard disk, you will need to use ZFS to implement the rest of the 9 hard disks. Part (a) Calculate, explain, and justify how do you plan and utilize the 9 hard disks? Sketch a diagram to help in your explanation. Appropriate RAID systems need to be used. (15 marks) Part (b) Install additional hard drives in your Debian virtual machine, and simulate the scenario using ZFS with relevant pools and reservations (For this task, you will need to install another 9 hard disks in your Debian virtual machine), Demonstrate what you have done with clear explanations and appropriate screen-shots.
