D-PVM-OE-01 Exam Dumps : Dell PowerMax Operate v.2

Step by Step Comprehensive Detailed Explanation:

The Dell PowerMax 2500 is a mid-range storage array designed for enterprise environments. It offers a balance of performance, capacity, and scalability.  

Scalability:The PowerMax 2500 scales from a single node pair to a maximum of two node pairs. This allows for increased performance and capacity as needed. Each node pair provides processing power, cache memory, and connectivity.

Why other options are incorrect:

A. Supports up to 16 nodes:This is incorrect. The PowerMax 8500, the higher-end model, supports up to 16 nodes.

B. Supports up to 15 PB of effective capacity:While the PowerMax 2500 offers significant capacity, its maximum effective capacity is lower than 15 PB.

D. Uses Storage Class Memory:Both the PowerMax 2500 and 8500 utilize Storage Class Memory (SCM) for enhanced performance.

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.
