Your customer needs a File & Print server that will maximize disk capacity. Fault Tolerance is not required. Which RAID Level should you recommend?

RAID 0, also known as disk striping, is the only RAID level that meets the customer's specific requirements. It combines multiple physical disks into a single logical volume by striping data across them. This configuration utilizes 100% of the available disk space for storage, thereby maximizing capacity. RAID 0 offers no data redundancy or fault tolerance; if any single drive in the array fails, all data is lost. Since the customer has explicitly stated that fault tolerance is not a requirement, RAID 0 is the ideal choice for maximizing storage capacity and performance.

A. RAID 5 uses the capacity equivalent of one disk for parity data to provide fault tolerance, which does not maximize capacity and adds an unrequired feature.
B. RAID 6 uses the capacity equivalent of two disks for parity data, offering a higher level of unrequired fault tolerance while further reducing the available capacity.
D. RAID 1 (mirroring) uses 50% of the total disk capacity to create an exact copy of the data for fault tolerance, which is the least efficient option for maximizing capacity.

1. HPE Smart Array SR Gen10 Controller User Guide:

"RAID 0 (striping)": "This level provides the highest performance and the best storage capacity but no fault tolerance. Any drive failure results in data loss." This directly supports the selection of RAID 0 for maximizing capacity when fault tolerance is not needed.

Page 23

"RAID 1 (mirroring)": "This level provides high performance and data protection by writing the same data on two drives." This confirms RAID 1 prioritizes protection over capacity.

Page 24

"RAID 5 (distributed data guarding)": "This level provides high performance and data protection by striping data and parity across all the drives in the array." This shows capacity is sacrificed for parity.

"RAID Level": The guide describes RAID 0 as having "No fault tolerance" and its primary advantage as "Highest performance

full capacity utilization." In contrast

it describes RAID 1

5

and 6 as having fault tolerance

which involves a capacity penalty for mirroring or parity.
