Okay, I understand. The task is to verify the completion of Non-Disruptive Migrations (NDM) and then remove the migration environment using the Unisphere for PowerMax simulator.

Here's a step-by-step guide on how to do this, based on typical Unisphere functionality and the context of the question:

Steps:

1. Launch the Simulator and Navigate to the Migration Section

Open Unisphere for PowerMax in your web browser.

Log in to the simulator.

In the left-hand navigation pane, locate the section related to migrations. This is usually under either:

Data Mobility

Migration

Expand the relevant section and click onMigrations(or a similar option like "Local Migrations" or "NDM"). This will take you to the view where you can manage Non-Disruptive Migrations.

2. Verify Migration Session Status

The Migrations view will list all current and past migration sessions.

Look for the following status indicators to confirm that the migrations have completed successfully:

Status:The status should typically be "Completed," "Cutover Complete," or a similar status indicating successful completion.

Progress:If a progress bar or percentage is shown, it should be at 100% or show that all data has been synchronized.

Important:If any sessions are still in a "Running," "Synchronizing," or other non-completed state, do not proceed with removing the migration environment. Wait for them to complete.

3. Select Completed Migrations for Removal

Once you've verified that all relevant migration sessions are successfully completed, select the sessions that you want to remove.

You can usually select sessions by:

Clicking a checkbox next to each session.

Clicking on the session itself (if the interface allows it).

4. Remove the Migration Environment

After selecting the completed migration sessions, look for an action button or menu option to remove them. This might be labeled:

"Remove"

"Delete"

"Cleanup"

"Remove Session"

Click the appropriate button to initiate the removal process.

Confirmation:You will likely be prompted with a confirmation message to make sure you want to remove the selected migration sessions. Verify that you have selected the correct sessions and confirm the removal.

5. Verify Removal (Optional)

After the removal operation completes, the Migrations view should refresh.

Verify that the migration sessions you removed are no longer listed.

Step by Step Comprehensive Detailed Explanation:

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 is24 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.

Step by Step Comprehensive Detailed Explanation:

The topology shown in the exhibit depictsCascaded SRDF. This SRDF configuration involves three storage arrays (or sites) connected in a chained or cascaded manner.

Here's how it works:

Primary Site (R1):The production host is connected to the primary storage array (R1).

Intermediate Site (R2):The primary array (R1) synchronously replicates data to an intermediate array (R2).

Remote Site (R2):The intermediate array (R2) then asynchronously replicates data to a remote array (also labeled R2 in the diagram).

This cascading setup provides a multi-hop disaster recovery solution, where data is first replicated synchronously to a nearby site for high availability and then asynchronously replicated to a further remote site for disaster recovery.

Why other options are incorrect:

B. SRDF/Star:SRDF/Star involves a central array replicating to multiple remote arrays in a star-like pattern.

C. SRDF/Metro:SRDF/Metro is designed for synchronous replication over short distances, typically within a metropolitan area.

D. Concurrent SRDF:Concurrent SRDF allows multiple SRDF relationships to exist simultaneously for the same device.
