In this task, you need to demonstrate the creation and usage of virtual machine using Debian OS. A logistic company ZSonic Pte Ltd has purchased a server with 12 hard disks (each hard disk has a storage size of 1 TB). The server is installed with Debian OS, and it has an operational life of 2 years. The requirements for the storage space are stated as follow: 3 TB is needed for the sales department to store various documents and videos. Redundancy is needed such that no data should be lost.

5 TB is needed for the operation department to store various documents. Redundancy is needed such that no data should be lost.

500 GB is needed for the accounting department to store various accounting reports. Redundancy is needed such that no data should be lost.

Each staff will be given 10 GB of home storage space, and there is a total of 80 staff. Redundancy is needed such that no data should be lost. 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 11 hard disks. (a) Explain and justify how do you plan and utilize the 11 hard disks? Sketch a diagram to help in your explanation. Appropriate RAID systems need to be used. (15 marks) (b) Install additional hard drives in your Debian virtual machine, and simulate the scenario using ZFS with relevant pools. (For this task, you will need to install another 11 hard disks in your Debian virtual machine.)

Demonstrate what you have done with clear explanations and appropriate screen-shots. (15 marks)
