Free Practice Questions for EMC D-PVM-OE-01 Exam

Mode can be Never, OnFailure, or Always › Never: Implies static even distribution (default) › OnFailure: On a failure, I/O limits are redistributed to online ports › Always: I/O limits are dynamically distributed based on demand

Step by Step Comprehensive Detailed Explanation:

In PowerMaxOS 5978, the largest TDEV (Thin Device) that can be created is64 TB. This represents the maximum size for a single, thinly provisioned storage volume on a PowerMax array running that version of the operating system.

Step by Step Comprehensive Detailed Explanation:

SnapVX Clones:SnapVX clones are full, writable copies of a source volume created using the SnapVX snapshot technology. They are independent volumes that can be used for various purposes, such as testing, development, or data analysis.

Secure Snapshots:SnapVX offers the capability to create "secure snapshots." When a clone is derived from a secure snapshot, it inherits the same protection, making it immutable and preventing any modifications or deletion. This ensures data integrity and protection against accidental or malicious changes.

Crash Consistent:SnapVX clones can be made crash consistent. This means that the clone captures a point-in-time copy of the source volume that is consistent with a database or application crash. This is important for ensuring data integrity and recoverability in situations where the source volume experiences an unexpected outage.

Why other options are incorrect:

A. Maximum 1024 snaps per volume:This limit applies to the source volume, not the clones themselves. Each clone is an independent volume.

C. Restores directly to the source volume:Clones are independent copies and do not directly restore to the source volume. Data can be copied or moved from the clone to the source if needed.

D. Is Read-only:SnapVX clones are fully writable copies, not read-only.

We need to provision 2 TB of storage to the ESXi1 host on a PowerMax array (SID 1762) using Unisphere, in a multi-tenant environment. We'll use auto-provisioning with the following specifics:

Storage Group Name:ESXi1_SG

Port Group:(A new port group with Directors OR-1C:0 and OR-2C:0)

Volume Size:2 TB (single volume)

Other Settings:Default

Here are the step-by-step instructions, tailored for the Unisphere simulator as described in the question:

Steps:

1. Launch the Simulator and Navigate to Storage Groups

Open Unisphere for PowerMax in your web browser.

You should already be logged in to the simulator, with the PowerMax array with SID 1762.

In the left-hand navigation pane, click onStorage>Storage Groups.

2. Initiate Storage Group Creation

Click theCreatebutton (likely a plus "+" icon) in the Storage Groups section to start the Create Storage Group wizard.

3. Name the Storage Group

In the "Create Storage Group" wizard:

Storage Group Name:Enter ESXi1_SG.

Enable FAST/Service Level:Do not check this option, as we are leaving all other settings at their default.

ClickNextorContinue(the exact wording might vary).

4. Add Volumes

Ensure"Create new volumes"is selected.

Number of Volumes:Enter 1.

Volume Size:

Enter 2.

Select TB from the dropdown for the unit.

ClickNext.

5. Create the Port Group

You should now be on the "Connectivity" or "Host" step, where you will add a new port group.

Select "Create Port Group"

Port Group Name:Give the new port group a name. You can use something descriptive like "ESXi1_PG," or any name that follows your organization's naming conventions.

Select Ports:

Find and select the following Directors and ports from the list of available ports:

OR-1C:0

OR-2C:0

Note:The simulator may not allow you to highlight the exact director ports as in a production environment. It will likely display all directors and ports under the selected array. Just ensure they are selected as part of the port group.

ClickNext.

6. Add host to the Masking View

Select "Add Host"

Select "Create New Host"

Host Name:ESXi1

Initiators:You don't have specific initiators to add in this simulation, so you can skip this part or add any from the available options. This is because we are working within a simulated environment.

ClickNext

7. Review and Create

You'll be presented with a summary page that shows:

Storage Group: ESXi1_SG

Volume: 1 x 2 TB volume

Port Group: (The new port group you created with OR-1C:0 and OR-2C:0)

Host: ESXi1

Carefully review all the settings to make sure they are correct.

ClickRun NoworFinish(or similar wording) to create the storage group, volume, port group, and masking view.

8. Verification (Optional)

After the operation completes, you can verify the results:

Go back to theStorage Groupslist. You should see the ESXi1_SG storage group.

Click on ESXi1_SG to view its details. You should see the 2 TB volume and the associated host (ESXi1) and port group.

You can also navigate toHosts>Port Groupsto verify that the new port group was created correctly.

Finally, you can navigate toHosts>Masking Viewsto verify that a masking view was created correctly.
