You work as an IT support technician for a boss who believes you are really bright and can solve just
about any problem he throws at you. Folks in the company have complained one time too many that the
file server downtime is just killing them, so he asks you to solve this problem. He wants you to figure out
what hardware is needed to implement hardware RAID for fault tolerance. You check the file server’s
configuration and discover it has a single hard drive using a SATA connection with Windows Server
2016 installed. There are four empty bays in the computer case and four extra SATA power cords. You
also discover an empty PCIe ×4 slot on the motherboard. BIOS/UEFI setup does not offer the option to
configure RAID, but you think the slot might accommodate a RAID controller. Complete the
investigation and do the following:
1. Decide what hardware you must purchase and save or print webpages showing the products and their
cost.
2. What levels of RAID does the RAID controller card support? Which RAID level is best to use? Cite
any important information in the RAID controller documentation that supports your decisions.
3. What is the total hardware cost of implementing RAID? Estimate how much time you think it will take
for you to install the devices and test the setup.
Answer
Step 1 of 3:)
Because the server does not have an onboard RAID controller, we have to have an add-on RAID controller
card that can be fixed in the PCIe slot. In order to configure the hard drives in RAID, we need at least 4
port RAID controllers. I have attached a screenshot of a website that sells a 4 SAS/SATA slot RAID card.
Please note that we need to look at the port form when ordering, as the server only has SATA ports with
one SATA hard drive to use the new SATA HARD DRIVE. We need to purchase a RAID controller card
with SATA slots. We can achieve high performance with better RAID setup by removing the current HDD
and putting all SAS drives.
Step 2 of 3:)

The RAID controller we chosen will help RAID- 0,1,3,4,5,6. We need to look at performance vs.
availability when configuring the RAID as the goal of configuring RAID in this scenario is to achieve fault
tolerance. RAID 5 is the best RAID level to achieve performance along with fault tolerance.
RAID 5 consists of stripping block levels with distributed parity. Data will be written across all the
available drives in this process and parity will be written across all drives for each block.
Step 3 of 3:)
The overall hardware cost of a RAID implementation is around INR 15000/- approximately. Setting up
the RAID and checking the setup takes at least 1 day.
