The correct order of steps to create and operate a custom monitor is:

Determine the type and frequency of statistics to collect.

Create a monitor.

Add one or more sinks to the monitor.

Collect statistics.

Gather monitoring files, or monitor output from the console.

To create and operate a custom monitor within the Dell VPLEX environment, follow these steps:

Determine the Type and Frequency of Statistics to Collect: Identify what statistics are relevant for your monitoring purposes and how frequently they should be collected. This will depend on the specific needs of your environment and the performance metrics you wish to track.

Create a Monitor: Using the VPLEX CLI or Unisphere for VPLEX, create a new monitor instance. Configure the monitor with the types of statistics you determined in the previous step.

Add One or More Sinks to the Monitor: Sinks are the destinations where the collected statistics will be sent. These could be files, databases, or external systems. Set up one or more sinks in the monitor configuration to ensure that the data is stored or transmitted as needed.

Collect Statistics: Start the monitor to begin collecting statistics. The monitor will gather data from the VPLEX system according to the type and frequency settings you have specified.

Gather Monitoring Files, or Monitor Output from the Console: After the statistics have been collected, retrieve the monitoring files from the specified sinks, or view the output directly from the console if real-time monitoring is configured.

These steps are based on the standard procedures for setting up and managing custom monitors in a Dell VPLEX environment, as detailed in the Dell EMC VPLEX documentation. By following these steps, you can effectively monitor the performance and health of your VPLEX system.

To increase data protection by converting a local RAID-0 virtual volume to a distributed virtual volume, the recommended method is to create a corresponding device on the remote cluster and then attach it as a mirror to the existing local device. This process effectively creates a distributed virtual volume that spans across both clusters.

Create a Device on the Remote Cluster: Start by creating a new device on the remote VPLEX cluster. This device should be of the same size as the local RAID-0 virtual volume and should not have a virtual volume associated with it1.

Attach as a Mirror: Once the remote device is created, attach it as a mirror to the local RAID-0 virtual volume. This operation is performed using the VPLEX CLI and will begin the process of mirroring the data from the local device to the remote device1.

Synchronization: After attaching the remote device as a mirror, the VPLEX system will synchronize the data between the local and remote devices. This ensures that both devices have identical data and are in a consistent state1.

Distributed Virtual Volume: Once the synchronization is complete, the local and remote devices together form a distributed virtual volume. This volume now has increased data protection because it is distributed across two different clusters1.

Verification: Verify that the distributed virtual volume is functioning correctly by checking its status and ensuring that it is accessible from both clusters1.

Best Practices: It is important to follow the best practices for creating and managing distributed virtual volumes as outlined in the Dell VPLEX Deploy Achievement documents. This includes proper planning, execution, and verification of the mirroring process1.

In summary, the recommended method to change a local RAID-0 virtual volume to a distributed virtual volume is to create a corresponding device on the remote cluster and attach it as a mirror, thereby forming a distributed virtual volume with increased data protection.

The maximum number of synchronous consistency groups supported by VPLEX is 256. This number is determined by the system’s capabilities and is designed to ensure optimal performance and manageability.

Consistency Groups: Consistency groups in VPLEX are used to group multiple virtual volumes together to ensure write-order fidelity, which is crucial for applications requiring transactional integrity12.

Synchronous Operations: Synchronous consistency groups are particularly important for environments where data must be kept consistent across geographically dispersed clusters in real-time12.

System Limitations: The limit of 256 synchronous consistency groups is set to balance the system’s performance with the need for data consistency. It ensures that the system can maintain the required performance levels while providing the data protection and availability features12.

Configuration and Management: Administrators must carefully plan and manage the consistency groups within the limits of the system to ensure that all critical data is protected and that the system operates efficiently12.

Documentation Reference: For detailed information on configuring and managing consistency groups, administrators should refer to the Dell VPLEX Deploy Achievement documents and best practice guides12.

In summary, the verified answer to the maximum number of synchronous consistency groups supported by VPLEX is 256. This limitation is part of the system design to ensure high availability and performance.
