Dell EMC D-PVM-OE-01 Exam Dumps

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 on Storage > Storage Groups.

2. Initiate Storage Group Creation

Click the Create button (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.

Click Next or Continue (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.

Click Next.

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.

Click Next.

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.

Click Next

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.

Click Run Now or Finish (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 the Storage Groups list. 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 to Hosts > Port Groups to verify that the new port group was created correctly.

Finally, you can navigate to Hosts > Masking Views to verify that a masking view was created correctly.

Host I/O Limits in PowerMax allow you to control the maximum IOPS (Input/Output Operations Per Second) or bandwidth that a storage group can consume. This helps prevent performance issues caused by one application or workload monopolizing resources. When setting Host I/O Limits, you can choose from different dynamic I/O distribution modes:

Never: This is the default mode. It means that the I/O limits are statically distributed across the directors in the associated masking view. If a director fails, its allocated portion of the I/O limit is lost.

Balanced: In this mode, the I/O limits are dynamically adjusted based on the number of online directors. If a director fails, its I/O limit is redistributed among the remaining online directors. This helps maintain performance even in the event of a director failure.

Always: This mode provides full dynamic distribution of I/O limits. The limits are continuously adjusted across all online directors based on the current workload and demand. This ensures optimal resource utilization and performance.

The Port Attributes page in Unisphere for PowerMax allows storage administrators to configure various settings related to the front-end ports on the storage array. One of the functions available on this page is Select Mgt Option.

This option allows you to specify how the port is used for management purposes:

Dedicated Management Port: You can designate a port as a dedicated management port, which is used exclusively for communication with management tools like Unisphere and Solutions Enabler.

Shared Management Port: You can configure a port to be shared for both management traffic and host I/O traffic.

This flexibility allows you to optimize port usage and segregate management traffic if needed.

Why other options are incorrect:

A . Manage Protocol: Protocol settings (like FC or iSCSI) are typically configured elsewhere in Unisphere, not on the Port Attributes page.

C . Volume Set Addressing: Volume Set Addressing is a feature related to mainframe connectivity and is not directly managed through the Port Attributes page.

D . ORS Ceiling: ORS (Open Replicator Solutions) settings are managed separately and not through the Port Attributes page.

The PowerMax 8500 is a high-end storage array designed for enterprise environments with demanding capacity requirements. The maximum capacity per array in a PowerMax 8500 is 24 petabytes effective (PBe).

This means that after considering data reduction technologies like deduplication and compression, the array can store up to 24 petabytes of usable data.

Why other options are incorrect:

A . 8 PBe, B. 18 PBe, C. 20 PBe: These values are lower than the actual maximum capacity of the PowerMax 8500.

You want a detailed, step-by-step guide on how to add three 100 GB volumes to an existing host and change the service level of the associated storage group from Gold to Platinum on a PowerMax array, using the Unisphere for PowerMax interface shown in the image.

Here's a comprehensive guide, broken down into manageable steps:

Phase 1: Provisioning the New Volumes

Step 1: Log in to Unisphere for PowerMax

Open your web browser and enter the URL for your Unisphere for PowerMax management interface.

Log in with your administrator credentials.

Step 2: Navigate to Storage Groups

In the left-hand navigation pane, click on Storage to expand the storage management section.

Click on Storage Groups under the Storage section. This will display a list of existing storage groups on your PowerMax array.

Step 3: Locate the Target Storage Group

Identify the storage group that currently contains the host's existing two 100 GB volumes.

Tip: You can find this by:

Looking at the 'Hosts' tab within each storage group's details. It will list the hosts connected to that storage group.

If you know the host's name, you might be able to search for it using the Unisphere search bar (if available).

Step 4: Initiate Adding Volumes

Once you've found the correct storage group, select it by clicking on its name.

Look for a button or option related to adding volumes. The exact wording might vary slightly depending on your Unisphere version, but it could be:

'Add to Storage Group'

'+' (a plus icon, which often signifies adding something)

'Add Volumes'

Click this button to start the process of adding new volumes to the storage group.

Step 5: Configure Volume Details

A new window or panel will appear, allowing you to specify the characteristics of the new volumes.

Select 'Create new volumes'

Number of Volumes: Enter 3 in the field for the number of volumes.

Capacity: Enter 100 in the field for the capacity of each volume. Make sure the unit is set to GB.

Volume Name (Optional): You can give the volumes a specific name or prefix, or you can let Unisphere auto-generate names.

Service Level: Since the final goal is to move the entire Storage Group to platinum, you can either set this to platinum now or change it for the whole group later.

Other Settings: Review any other available settings (e.g., thin provisioning, data reduction). In most cases, the default settings should be fine, but adjust them if needed based on your environment's best practices.

Step 6: Execute Volume Creation

After you've configured all the volume settings, review them carefully to make sure they are correct.

Click the button to execute the operation. This button might be labeled:

'Run Now'

'OK'

'Finish'

'Apply'

Unisphere will start creating the new volumes. This might take a few moments.

Phase 2: Changing the Storage Group's Service Level

Step 7: Navigate Back to Storage Groups

Once the volume creation is complete, go back to the list of storage groups. You can usually do this by clicking 'Storage Groups' in the left-hand navigation pane again.

Step 8: Select the Target Storage Group

Find the same storage group you worked with in Phase 1 (the one containing the host's volumes).

Click on the storage group's name to open its properties.

Step 9: Modify the Service Level

Look for a setting related to the 'Service Level.' It might be a dropdown menu, a field you can edit, or a link to a separate settings page.

Change the Service Level from Gold to Platinum.

Step 10: Save the Changes

Click the button to save the changes to the storage group's service level. This button might be labeled:

'Apply'

'Save'

'OK'

Phase 3: Host-Side Configuration

Step 11: Rescan for New Storage on the Host

The host needs to be made aware of the newly provisioned storage. The exact process for this depends on the host's operating system:

Windows:

Open Disk Management (diskmgmt.msc).

Go to Action > Rescan Disks.

Linux:

Identify the SCSI host bus numbers (e.g., ls /sys/class/scsi_host).

Use the command echo '- - -' > /sys/class/scsi_host/hostX/scan, replacing hostX with the appropriate host bus number.

You might also be able to use tools like rescan-scsi-bus.sh.

VMware ESXi:

In the vSphere Client, select the host.

Go to Configure > Storage Adapters.

Select the relevant storage adapter (e.g., your HBA).

Click Rescan Storage.

Step 12: Initialize, Partition and Mount (if needed):

Once the host detects the new volumes, you'll need to initialize them, create partitions, format them with a filesystem, and mount them, depending on your operating system and how you intend to use the storage. This is done using the host's operating system tools.

Phase 4: Verification and Monitoring

Step 13: Verify in Unisphere

Go back to the storage group in Unisphere and check the 'Volumes' tab. You should see the three new 100 GB volumes listed along with the original two, and they should all have the 'Platinum' service level.

Step 14: Verify on the Host

Confirm that the host can see and access the new volumes.

Step 15: Monitor Performance

After making these changes, monitor the performance of the storage group and the application using Unisphere's performance monitoring tools. Ensure that the Platinum service level is meeting your application's requirements
