Question 2 Demonstrate the creation and usage of virtual machine using Ubuntu OS. Scenario: A florist business BeautyFlower has purchased an Ubuntu server with 8 hard disks (each hard disk has a storage size of 1.5 TB). The server is pre-installed with Ubuntu 22.04 LTS (Jammy Jellyfish), and it has an operational life of 3 years. The requirements for the storage space are stated as follow: 1.2 TB is needed for storing transactions records such as order entry, delivery, and back-office accounting purpose. As these are important operational data, no data should be lost, and redundancy is a must. 1 TB is needed for the marketing department to store various marketing materials to promote the florist shop. Redundancy is important and no data should be lost. 1.1 TB is needed for each florist shop (total 3 florist shops) to store flower related materials. Redundancy is needed such that no data should be lost. A temporary storage space for all the staff for quick sharing of non-sensitive information. It is estimated that this space will need 1.1 TB in the first year, and it will increase 20% in the second year, and it will grow by 30% (from second year) in the third year. Performance is important but no redundancy is needed. Besides a hard disk that host the Ubuntu OS, ZFS needs to be used to implement the rest of the 7 hard disks.

Illustrate what RAID system(s) should be used for the scenario and why. Note that you will need to calculate and explain how you plan and utilize the 7 hard disks. Sketch a diagram to help in your explanation.
