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.
