For zoning FC WAN COM ports on a VPLEX Metro, the requirement is that each WAN COM port in the local cluster must be zoned to all WAN COM ports in the remote cluster. This setup ensures that there is a redundant network capability where each director on one cluster communicates with all the directors on the other site, even in the event of a fabric or network failure 1 .

Zoning Configuration : The zoning needs to be fixed such that all A2-FC00 only see (are zoned with) remote A2-FC00 ports, and similarly for A2-FC01 with A2-FC01, and so on for all WAN COM ports 1 .

Redundant Network : This zoning configuration provides a redundant network capability, which is essential for maintaining communication between the two VPLEX clusters in a Metro configuration 1 .

Fabric Separation : The FC WAN COM ports will be connected to dual separate backbone fabrics or networks that span two sites, allowing for data flow between the two VPLEX clusters without requiring a merged fabric between the two sites 1 .

Best Practices : For configuring FC WAN COM ports, it is recommended to refer to the “Implementation and Planning Best Practices for EMC VPLEX Technical Notes” provided by Dell 1 .

In summary, the requirement for zoning FC WAN COM ports on a VPLEX Metro is to ensure that each WAN COM port in the local cluster is zoned to all WAN COM ports in the remote cluster, providing a robust and fault-tolerant communication network.

Best Practices : It is important to follow the best practices for creating distributed devices as outlined in the Dell VPLEX Deploy Achievement documents. This includes ensuring that the local devices are properly configured and that the VPLEX clusters are in a healthy state before creating the distributed device 1 .

In summary, the ds dd create command is used to create a distributed device from specified local devices in a Dell VPLEX environment. This command is a fundamental part of managing distributed storage within VPLEX and is essential for achieving high availability and data mobility across clusters.

In a VPLEX system, each director module has front-end (FE) and back-end (BE) ports for connectivity. The FE ports are used to connect to hosts or out-of-fabric services such as management networks. Based on standard configurations and assuming that Director-A and Director-B are mirrored in layout, the number that highlights the Director-B front-end ports is typically 2 1 .

Director Modules : VPLEX systems consist of director modules, each containing ports designated for specific functions. Director-B is one of these modules 1 .

Front-End Ports : The front-end ports on Director-B are used for host connectivity and are essential for the operation of the VPLEX system 1 .

Port Identification : During the installation and setup of a VPLEX system, correctly identifying and utilizing the FE ports is crucial. This includes connecting the VPLEX to the host environment and ensuring proper communication between the storage system and the hosts 1 .

Documentation Reference : For precise identification and configuration of the FE ports on Director-B, the Dell VPLEX Deploy Achievement documents provide detailed instructions and diagrams 1 .

Best Practices : It is recommended to follow the guidelines provided in the Dell VPLEX documentation for port identification and installation utilities to ensure correct setup and configuration of the VPLEX system 1 .

In summary, the number 2 in the exhibit corresponds to the Director-B front-end ports in a Dell VPLEX system, which are critical for host connectivity and system operation.

During a VPLEX installation, the front-end ports are enabled after the metadata volumes and backup have been created. This sequence ensures that the system’s metadata, which is crucial for the operation of VPLEX, is secured before the storage is exposed to the hosts.

Metadata Volumes Creation : The first step in the VPLEX installation process involves creating metadata volumes. These volumes store configuration and operational data necessary for VPLEX to manage the virtualized storage environment 1 .

Metadata Backup : After the metadata volumes are created, it is essential to back up this data. The backup serves as a safeguard against data loss and is a critical step before enabling the front-end ports 1 .

Enabling Front-End Ports : Once the metadata is secured, the front-end ports can be enabled. These ports are used for host connectivity, allowing hosts to access the virtual volumes presented by VPLEX 1 .

Exposing Storage to Hosts : With the front-end ports enabled, the storage can then be exposed to the hosts. This step involves presenting the virtual volumes to the hosts through the front-end ports 1 .

Final Configuration : The final configuration steps may include zoning, LUN masking, and setting up host access to the VPLEX virtual volumes. These steps are completed after the front-end ports are enabled and the storage is exposed 1 .

In summary, the front-end ports are enabled during a VPLEX installation after the metadata volumes and backup have been created, which is reflected in option D. This ensures that the system metadata is protected and available before the storage is made accessible to the hosts.

To configure EMC Secure Remote Services (ESRS) for VPLEX, certain key pieces of information are required:

ESRS Gateway Account : An account on the ESRS Gateway is necessary to enable secure communication between the VPLEX system and EMC’s support infrastructure 1 .
