EMC Dell VPLEX Operate Achievement D-VPX-OE-A-24 Exam Dumps: Updated Questions & Answers (December 2025)

In a VPLEX Metro environment, the write rate on distributed volumes has a direct impact on VPLEX performance with respect to WAN bandwidth. Here’s how:

Distributed Volumes: Distributed volumes in VPLEX Metro span across two geographically separated clusters and are designed to provide continuous availability and data mobility1.

Write Operations: Write operations on distributed volumes require data to be written to both clusters before an acknowledgment is sent back to the host.This ensures data consistency across both sites2.

WAN Bandwidth: The Wide Area Network (WAN) bandwidth between the two clusters is a critical factor in the performance of these write operations.If the WAN bandwidth is insufficient, it can lead to increased latency and reduced throughput3.

Performance Impact: With only half the available WAN-COM paths, VPLEX can exceed bandwidth limitations on the existing WAN-COM paths, causing severe latency impacting the remote writes of distributed devices3.

Best Practices: VPLEX best practices indicate that the round-trip time (RTT) between VPLEX clusters shouldn’t exceed 5 ms to provide the best performance, and an RTT of 1 ms is recommended for a campus-wide network2.

By managing the write rate on distributed volumes and ensuring adequate WAN bandwidth, VPLEX Metro can maintain high performance and meet the required service levels for data availability and accessibility.

In VPLEX, the type of statistic that provides an instantaneous value displaying CPU utilization and memory utilization is referred to as “counters.” These counters offer real-time metrics that reflect the current state of the system’s resources.

Counters: Counters are a type of statistic in VPLEX that provide immediate, real-time values for various system metrics, including CPU and memory utilization.They are used to monitor the current performance and resource usage of the VPLEX system1.

CPU Utilization: CPU utilization counters show the percentage of CPU resources currently being used by the VPLEX directors.This information is crucial for understanding the load on the system and for capacity planning1.

Memory Utilization: Memory utilization counters display the amount of RAM currently in use by the VPLEX system.This helps administrators monitor memory consumption and ensure that the system has enough memory to operate efficiently1.

Monitoring and Management: Counters are an essential tool for the ongoing monitoring and management of a VPLEX environment.They help administrators identify potential performance bottlenecks and take proactive measures to optimize system performance1.

Instantaneous Values: Unlike other statistics that may provide averages or aggregated data over a period, counters offer instantaneous snapshots of resource usage, making them ideal for real-time monitoring1.

By utilizing counters, VPLEX administrators can gain immediate insights into the system’s CPU and memory utilization, enabling them to maintain optimal performance and address issues as they arise.

To add a RecoverPoint cluster to VPLEX, the RecoverPoint cluster Management IP address is required. This IP address is used to establish communication between the VPLEX system and the RecoverPoint cluster for management and replication purposes.

RecoverPoint Cluster Management IP Address: The management IP address is a unique identifier that allows the VPLEX system to connect to the RecoverPoint cluster.It is used for configuration, management, and monitoring of the RecoverPoint system from VPLEX1.

Adding a RecoverPoint Cluster: To add a RecoverPoint cluster to VPLEX, the administrator must use the VPLEX CLI and provide the management IP address of the RecoverPoint cluster.This is done using the rp rpa-cluster add command followed by the -o option to specify the IP address1.

Authentication: After providing the IP address, the administrator will be prompted to enter the administrative password for the RecoverPoint cluster to authenticate the connection1.

Verification: Once the RecoverPoint cluster is added, the administrator can verify the addition by using the ls recoverpoint/rpa-clusters/ command to list the RecoverPoint clusters connected to VPLEX1.

Management and Replication: With the RecoverPoint cluster added to VPLEX, the system can manage replication tasks and ensure data protection across the connected storage systems1.

By providing the RecoverPoint cluster Management IP address, administrators can integrate RecoverPoint with VPLEX, enhancing the system’s capabilities for data replication and disaster recovery.

Physical Port Numbering: Physical ports on I/O modules are numbered to provide a unique identifier for each port. This numbering is important for configuration, management, and troubleshooting purposes.

Director Modules: In VPLEX hardware, director modules are key components that manage data flow and connectivity. Each director module contains I/O modules with multiple physical ports.

Numbering Convention: The numbering convention for physical ports may start from either the top or the bottom of the I/O module, depending on the design specifications provided by the manufacturer1.

VS6 VPLEX Hardware: For the VS6 VPLEX hardware, the specific numbering of physical ports for each I/O module would be detailed in the official Dell VPLEX documentation, which would provide diagrams and descriptions of the hardware components2.

Configuration and Setup: Understanding the physical port numbering is crucial for the proper configuration and setup of the VPLEX system, as it affects zoning, mapping, and other storage network configurations3.

Since the exact numbering of physical ports for each I/O module in VS6 VPLEX hardware is not provided in the search results, it is recommended to consult the official Dell VPLEX documentation or contact Dell support for verified information.

Volume expansion in Dell VPLEX is a process that allows for increasing the size of a virtual volume. However, certain conditions can prevent this operation from taking place:

Migration Occurring on the Volume: If there is an ongoing migration process involving the volume, it cannot be expanded until the migration is complete.This is because the volume’s data layout is being altered during migration, and any attempt to change its size could lead to data corruption or other issues1.

Consistency Group Membership: Whether or not a volume belongs to a consistency group does not directly prevent volume expansion. Consistency groups in VPLEX areused to ensure write-order fidelity across multiple volumes but do not restrict the expansion of individual volumes within the group.

Metadata Volume Backup: Backing up a metadata volume is a separate operation that does not interfere with the ability to expand a storage volume. Metadata backups are typically performed to preserve the configuration and state information of the VPLEX system.

Logging Volume Re-synchronization: While a logging volume in a re-synchronization state indicates that there is an ongoing process to align data across clusters or devices, it does not inherently prevent the expansion of a storage volume.

Therefore, the condition that would prevent volume expansion is when there is a migration occurring on the volume (OA).

When provisioning LUNs from an ALUA-capable back-end array to VPLEX, it is required that each VPLEX director has at least two paths to both the active and non-preferred array controllers. This ensures redundancy and continuous availability of data even if one path or controller fails.

ALUA-Capable Arrays: ALUA (Asymmetric Logical Unit Access) arrays present active and non-preferred (or passive) paths to the storage.The active paths are used for I/O under normal operations, while non-preferred paths are available for use if the active paths fail1.

Path Requirements: For each VPLEX director, there should be at least two paths to the active controller and at least two paths to the non-preferred controller.This configuration provides redundancy and supports the ALUA functionality1.

VPLEX Director Connectivity: VPLEX directors manage the paths to the storage arrays.Having multiple paths from each director ensures that VPLEX can continue to provide access to the LUNs even if there are issues with one of the paths or controllers1.

Redundancy and Availability: The path requirement is crucial for maintaining high availability and redundancy, which are key benefits of using VPLEX in conjunction with ALUA-capable arrays1.

Best Practices: Following this best practice for path connectivity aligns with VPLEX’s goal of providing continuous data availability and seamless failover capabilities in the event of hardware failures or maintenance activities1.

By adhering to the path requirement of having at least two paths to both the active and non-preferred array controllers, VPLEX can leverage the ALUA functionality of the back-end array to ensure optimal performance and data availability.

In VPLEX, a storage volume is a logical representation of physical storage, and it can be divided into multiple extents.An extent is a contiguous range of block addresses within a storage volume that VPLEX manages as a single unit1.

Storage Volume: This is the physical storage presented to VPLEX from the backend storage arrays.It represents the total capacity available for use in VPLEX1.

Extent: An extent is a subset of a storage volume.It is a logical division within a storage volume that VPLEX uses to create virtual volumes1.

Division into Extents: A storage volume can be split into multiple extents, allowing for more granular management of storage resources.This is useful for creating multiple virtual volumes from a single storage volume1.

Virtual Volume Creation: Extents are used by VPLEX to create virtual volumes.By splitting a storage volume into extents, VPLEX can combine extents from different storage volumes to create a virtual volume1.

Management Flexibility: The ability to split a storage volume into multiple extents provides flexibility in storage management, enabling VPLEX to optimize storage utilization and performance1.

By splitting a storage volume into multiple extents, VPLEX can efficiently manage and allocate storage resources, creating virtual volumes that meet the specific needs of applications and workloads.

To streamline the encapsulation process of LUNs across multiple servers to a VPLEX Metro cluster, the storage administrator can use the VIAS (VPLEX Integrated Array Services) Provisioning Wizard. This tool simplifies the process by automating many of the steps involved in encapsulating LUNs.

Here’s how the VIAS Provisioning Wizard can help:

Preparation: The administrator can prepare many of the encapsulation tasks ahead of time, such as host zoning to VPLEX FE ports, host registration of initiators in VPLEX, and LUN masking/zoning to the VPLEX BE Ports1.

Encapsulation Process: During the outage window, the administrator can use the VIAS Provisioning Wizard to encapsulate the LUNs under VPLEX control.Since the preparation steps like LUN masking and zoning to VPLEX BE have already been prepped, the cutover process becomes quicker1.

Storage View Container Creation: The VIAS Provisioning Wizard allows for the creation of a Storage View container in VPLEX, where only the VPLEX FE ports are included initially1.

EZ Provisioning Wizard: After claiming and encapsulating the LUNs, the administrator can create a 1:1 mapping of Storage volume to virtual volume with the EZ Provisioning Wizard, which is a quick process and helps preserve the data in its current state1.

Finalizing the Cutover: The newly encapsulated 1:1 virtual volumes are added to the previously created Storage View container, and the previously registered host initiators are added to the Storage View as well1.

By using the VIAS Provisioning Wizard, the administrator can efficiently manage the encapsulation of a large number of LUNs, reducing the complexity and duration of the outage window required for such a task.
