Step by Step Comprehensive Detailed Explanation:

Solutions Enabler (SE) uses various daemons (background processes) to perform different functions. The storstpd daemon is specifically responsible for:

Collecting Performance Statistics:It gathers performance data from the connected storage arrays, such as I/O rates, response times, and other metrics.

Managing Performance Data:It stores and manages the collected performance statistics, making them available for monitoring and analysis through tools like Unisphere for PowerMax.

This data is crucial for understanding the performance of the storage arrays, identifying potential bottlenecks, and optimizing storage resources.

Why other options are incorrect:

B. Coordinates storage array locks and application syscalls:This is the function of the storapid daemon.

C. Starts the system watchdog timer periodically:This is not directly related to the storstpd daemon.

D. Performs remote Solutions Enabler API functions:This is typically handled by the storsrvd daemon.
