Suppose you turn on a system and everything is dead – no lights, nothing on the monitor screen, and no spinning fan or hard drive. You verify that the power to the system works, all power connections and power cords are securely connected, and all pertinent switches are turned on. You can assume the power supply has gone bad. It’s time to replace it.

CIS 291 Wk 5 Discussion – RAID Selection

Post a total of 3 substantive responses over 2 separate days for full participation. This includes your initial post and 2 replies to classmates or your faculty member.

Due Thursday

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 that 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.

Research RAID and discuss the following in a minimum of 175 words:

• What hardware do you need to purchase? Share with the class the web pages showing the products and their costs.
• 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.
• 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.
• Why did you choose this RAID controller? Share your reasoning with the class.
