Your boss is impressed with the information you presented to the president on the Hard Drive project, so he asks you for your input on another issue.

Folks in the company have complained time after time that the file server downtime is bogging down their work. He would like to know what would be needed to implement Hardware RAID for speed and fault tolerance.

You check the file servers configuration and discover it has a single hard drive using a Serial Attached SCSI connection with Windows Server 2012 installed. There are four empty bays in the computer case and four extra power cords. There is also an empty PCIe x4 slot on the motherboard. BIOS setup does not offer the option to configure RAID but you think the slot might accommodate a SAS RAID controller card.

Investigate and do the following:

Decide what hardware you must purchase and screen print or attach web pages showing the products and their cost.

What levels of RAID does the RAID controller card support? Which RAID level is best to use for speed and redundancy? Screen print or attach any important information in the RAID controller documentation that supports your decisions.

What is the total hardware cost of implementing RAID? How much time do you think it would take for you to install the devices and test the setup? $655.00 this would only take about 10 minutes to install the hardware and twenty minutes to test.
