Question

A technician is talking to end users about the specifications for an upgraded application server. The users of the application report that there cannot be any unscheduled downtime or data loss. Additionally, they would like the performance of the application to improve over the previous server in any way possible. The previous running server was RAID 5. Which of the following RAID solutions should be implemented according to this scenario?

Answer 1

Answer: RAID 10

Explanation: RAID is a data storage technology that joins various physical disk drives into 1 or more logical units. The aim of this is to improve performance, reduce data redundancy, or to incorporate both of these aspects.

RAID 1+0 or RAID 10, makes use of a minimum of 4 disks, to stripe data across these disks in pairs. This action combines disk striping with disk mirroring to protect data. Data is retrieved so long as 1 disk in the mirrored pair is operational. These functions can improve the system that the technician is trying to fix.
