EMC D-PVM-OE-01 Exam With Confidence Using Practice Dumps

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.

Step by Step Comprehensive Detailed Explanation:

Unisphere for PowerMax offers different deployment options to manage PowerMax storage arrays. Based on the exhibit, we can identify the following:

Separate SYMAPI Server:The diagram shows a dedicated SYMAPI server. SYMAPI (Symmetrix Application Programming Interface) is a command-line interface used to manage PowerMax and VMAX storage arrays. This indicates that the Unisphere server is not directly connected to the storage arrays.

Unisphere Server Connected to SYMAPI Server:The Unisphere server is shown to be connected to the SYMAPI server. This means that the Unisphere server relies on the SYMAPI server to communicate with the PowerMax arrays.

No Direct Connection to Arrays:The Unisphere server does not have a direct connection to the PowerMax arrays.

Considering these points, the deployment option depicted in the exhibit is aremote deployment. In a remote deployment, the Unisphere server is installed on a separate host and communicates with the PowerMax arrays through a SYMAPI server. This allows for centralized management of multiple arrays from a single Unisphere instance.

Why other options are incorrect:

A. Embedded:In an embedded deployment, the Unisphere software runs directly on the PowerMax array itself. This eliminates the need for a separate Unisphere server.

B. Either remote or local:While the diagram could technically represent a local deployment with a dedicated SYMAPI server, the presence of the separate SYMAPI server and the lack of direct connection to the arrays strongly suggest a remote deployment.

D. Local:In a local deployment, the Unisphere server is typically installed on the same host as Solutions Enabler, which has direct connectivity to the storage arrays.
