Dell EMC Exam D-PVM-OE-01 Topic 8 Question 7 Discussion

Step by Step Comprehensive Detailed

Dell PowerMax storage arrays utilize different device types for various purposes. Solutions Enabler (SYMCLI) and Unisphere for PowerMax are management tools that can interact with these device types. Here's a breakdown:

SRDF Thin Devices (RDF1 or RDF2): These devices are specifically used for SRDF (Symmetrix Remote Data Facility) replication. RDF1 devices represent the local copy of data in an SRDF relationship, while RDF2 devices represent the remote copy. Both Solutions Enabler and Unisphere can manage these devices to configure and monitor SRDF replication.

Internal Thin Devices (Int+TDEV): These are thin provisioned devices that reside within the PowerMax storage array. They are used for general storage purposes and can be managed by both Solutions Enabler and Unisphere for tasks like provisioning, allocating capacity, and monitoring performance.

Thin Devices (TDEV): This is a general term for thin provisioned devices in PowerMax. Thin provisioning allows for efficient storage utilization by allocating capacity on demand. 1 Both Solutions Enabler and Unisphere can manage these devices.

Why other options are incorrect:

B . Thin BCV Devices (BCV+TDEV): BCV (Business Continuance Volume) devices are used for creating point-in-time copies for disaster recovery. While Solutions Enabler can manage BCV devices, Unisphere for PowerMax has limited functionality for managing them directly.

D . Data Devices (TDATs): TDATs are physical devices within the PowerMax array. While Solutions Enabler can interact with TDATs at a lower level, Unisphere for PowerMax primarily focuses on managing logical devices and storage groups.
