EMC Information Storage Fundamentals — Question 1

An application generates 8400 small random I/Os at peak workloads with a read/write ratio of 2:1. What is the disk load at peak activity for a RAID 1/0 configuration?

Answer options

• A. 5600
• B. 11200
• C. 16800
• D. 22400

Correct answer: B

Explanation

In a RAID 1/0 configuration, each I/O operation is mirrored and striped. With a read/write ratio of 2:1, there are 5600 reads and 2800 writes, resulting in a total of 11200 disk operations. The other options do not accurately represent the calculated disk load based on the given I/O and RAID configuration.
