Which type of devices can be tuned using the synchronous write bias properly by selecting values of either latency or throughput?
A. block devices
B. quantum devices
C. log devices
D. cache devices
Correct Answer: C
Explanation/Reference:
Explanation:
The Synchronous Write Bias setting controls the behavior when servicing synchronous writes. By default, the system optimizes synchronous writes for latency, which leverages the log devices to provide fast response times. In a system with multiple disjointed filesystems, this can cause contention on the log devices that can increase latency across all consumers. Even with multiple filesystems requesting synchronous semantics, it may be the case that some filesystems are more latency-sensitive than others.
