Question

An administrator is building a server that will run a data warehousing application. The server was ordered with eight 300GB drives. The application requires a dedicated storage location for the OS and one for critical files. The critical file storage needs fast access but must provide high redundancy. The OS requires 100GB and the file requires 950GB. Which of the following configurations will BEST suit the data warehouse needs?

Options

  • AOS: 3 Drives, RAID 1 with hot spare
  • BOS: 2 Drives, RAID 1
  • COS: 2 Drives, RAID 0
  • DOS: 2 Drives, RAID 1

Why each option

For a data warehousing server requiring 100GB for the OS and high redundancy, a RAID 1 configuration with two 300GB drives provides the best balance of redundancy and sufficient capacity.

AOS: 3 Drives, RAID 1 with hot spare
BOS: 2 Drives, RAID 1
COS: 2 Drives, RAID 0

RAID 0 provides no redundancy, meaning the failure of a single drive would result in complete data loss for the operating system, making it unsuitable for a critical server.

DOS: 2 Drives, RAID 1Correct

Using two drives in a RAID 1 configuration provides mirroring for the OS, ensuring high redundancy and fault tolerance for the operating system, which is crucial for a critical server. This setup also provides 300GB of usable space, satisfying the 100GB OS requirement efficiently.
