D-VXR-OE-23 Exam Dumps - EMC Storage Administrator Questions and Answers

To upgrade a VxRail cluster to the latest recommended version at a dark site (an environment without internet access), follow these steps:

Log in to VxRail Manager:

Open a web browser and navigate to the VxRail Manager URL.

Log in using the credentials:

Username: root

Password: VMw@r3!123.

Check Current Version and Compatibility:

Once logged in, navigate to the Dashboard to view the current version of VxRail.

Verify compatibility with the target upgrade version by reviewing the VxRail Release Notes or Upgrade Guide for your specific version.

Download Upgrade Bundle:

Since the site is dark, download the necessary upgrade bundle from Dell EMC’s support site using another system with internet access.

Save the upgrade bundle to a portable storage device (USB drive, external HDD, etc.).

Upload the Upgrade Bundle to VxRail Manager:

Connect the portable storage device to a local machine within the dark site.

In VxRail Manager, navigate to the Internet Upgrade section.

Select Local Upgrade and browse to the location of the upgrade bundle on your local machine.

Upload the upgrade bundle.

Perform the Upgrade:

After the bundle is uploaded, follow the on-screen prompts to begin the upgrade process.

The upgrade wizard will guide you through pre-upgrade checks, including verifying compatibility and ensuring cluster health.

Monitor the Upgrade Progress:

The upgrade process will take some time. Monitor the progress via the VxRail Manager interface.

Ensure there are no errors or issues reported during the upgrade.

Post-Upgrade Verification:

Once the upgrade is complete, verify that the VxRail Manager and vCenter report the new version correctly.

Check the health and status of the cluster to ensure all components are operational.

To prepare the system for maintenance mode and avoid unnecessary vSAN re-synchronization, follow these steps:

Log in to vSphere Client:

Open the vSphere Client.

Enter the username: administrator@vsphere.local.

Enter the password: VMw@r3!123.

Click Login.

Navigate to the Host:

In the vSphere Client interface, navigate to Hosts and Clusters.

Expand the VxRail-DC and then the VxRail-Cluster.

Select the Host for Maintenance:

Select the host you plan to put into maintenance mode (e.g., vcluster730-esx01.edu.local, vcluster730-esx02.edu.local, etc.).

Enter Maintenance Mode:

Right-click on the selected host and select Enter Maintenance Mode.

In the Enter Maintenance Mode window, you will have several options for vSAN data migration. To avoid unnecessary re-synchronization, choose Ensure Accessibility.

Ensure Accessibility: This option makes sure that the data remains accessible during maintenance but does not immediately trigger full data migration. It is the best choice to avoid unnecessary re-synchronization during a short maintenance window.

Confirm Maintenance Mode:

Click OK to confirm the selection and put the host into maintenance mode.

Verify the Host Status:

Monitor the status to ensure the host enters maintenance mode without triggering excessive re-synchronization.

To calculate the additional vSAN capacity consumed when a 100 GB VM is vMotioned from Cluster-A to Cluster-B, consider the following:

Cluster-A: FTT = 2 and FTM = Erasure Coding (RAID 6), which uses approximately 1.5 times the data size, thus 100 GB VM uses about 150 GB of vSAN capacity.

Cluster-B: FTT = 2 and FTM = Mirroring (RAID 1), which uses 3 times the data size, thus 100 GB VM uses 300 GB of vSAN capacity.

The difference in vSAN capacity consumed between Cluster-B and Cluster-A is: 300 GB (Cluster-B) - 150 GB (Cluster-A) = 150 GB

So, Cluster-B consumes 150 GB more vSAN capacity than Cluster-A.

In a VxRail deployment, the VMkernel interface used for vSAN traffic is typically vmk1. This interface is designated specifically for vSAN communication, ensuring that the storage traffic is segregated from other types of network traffic for performance and security reasons.

In VxRail networks, the vSAN and vMotion networks support link aggregation. Link aggregation (also known as NIC teaming) allows multiple network interfaces to be combined into a single logical interface, providing redundancy and increased throughput. This is particularly beneficial for vSAN traffic, which requires high bandwidth and low latency, and vMotion traffic, which benefits from increased network performance during virtual machine migrations.

The duration of the evaluation licenses for vSphere ESXi included with the VxRail system is 45 days. This trial period allows users to explore and test the features and capabilities of vSphere ESXi before committing to a full license.
