Which configuration provides maximum availability and performance?
Suggested Answer:
B
Triple mirrored
Data is triply mirrored, yielding a very highly reliable and high-performing system (for example, storage for a critical database). This configuration is intended for situations in which maximum performance and availability are required. Compared with a two-way mirror, a three-way mirror adds additional IOPS per stored block and higher level protection against failures.
