An administrator is asked to provision a 1 TB volume to hold non-critical temporary data for a seismic-analysis application. The volume requires the highest possible IOPS.

In this scenario, which configuration would satisfy this requirement?

Answers
A.

RAID 6 Dynamic Disk Pool with a 256 KiB segment size

B.

RAID 5 volume group with a 256 KiB segment size

Answers
B.

RAID 5 volume group with a 256 KiB segment size

C.

RAID 0 volume group with a 32 KiB segment size

Answers
C.

RAID 0 volume group with a 32 KiB segment size

D.

RAID 6 Dynamic Disk Pool with a 32 KiB segment size

Answers
D.

RAID 6 Dynamic Disk Pool with a 32 KiB segment size

Suggested answer: C

Explanation:

Understanding the Requirements: The administrator needs to provision a 1 TB volume for non-critical temporary data that requires the highest possible IOPS.

Non-Critical Data: Since the data is non-critical, redundancy (data protection) is not the primary concern. Therefore, RAID 0, which does not provide redundancy but maximizes performance, is suitable.

Highest Possible IOPS: RAID 0 is known for providing the highest IOPS compared to other RAID levels because it stripes data across multiple disks, allowing simultaneous read/write operations.

Segment Size: A smaller segment size (32 KiB) will result in higher IOPS for small random I/O operations, which is typical in seismic-analysis applications.
