A temporary storage space for all the cafe staff for fast sharing of non-essential information. It is estimated that this space will need 2000 GB in the first year, and the space will increase by another 50% in the second year. No redundancy is needed although performance is important. 2. 2.2 TB is needed for chef and barista to store secret recipe and sensitive recordings of brewing of coffee and baking of cake. The coffee chain will come up new coffee and cake frequently, and redundancy is important for this storage space. 3. 1 TB is needed for each cafe (total 7 cafe) to store transactions and staff scheduling. Redundancy is needed such that no data should be lost. Note that besides the ubuntu OS, which is pre-installed in a hard disk, ZFS needs to be used to implement the rest of the 8 hard disks. Part (a) Illustrate and justify what RAID system(s) should be used for the scenario. Calculate and explain how do you plan and utilize the 8 hard disks? Sketch a diagram with necessary labelling such as hard disk used (/dev/sdb, /dev/sdc, etc.), pool name and file system name to help in your explanation. Part (b) Install additional hard drives in your ubuntu virtual machine and simulate the scenario using ZFS with relevant pools and reservations. For this task, you will need to install another 8 hard disks in your ubuntu virtual machine. Demonstrate what you have done with clear explanations and appropriate screenshots.
