Network File System (NFS)

"Network File System (NFS) is a distributed file storage mechanism that enables users to access and work with files and directories located on remote computers as if they were local."

In the OvalEdge application, the NFS connector allows you to crawl and sample profile the files or folders existing in the NFS instance.

Field Name


Connector Type

By default, the selected connection type is displayed as the NFS.

License Add Ons

All the connectors will have a Base Connector License by default that allows you to crawl and profile to obtain the metadata and statistical information from a datasource. 

OvalEdge supports various License Add-Ons based on the connector’s functionality requirements.

  • Select the Auto Lineage Add-On license that enables the automatic construction of the Lineage of data objects for a connector with the Lineage feature. 
  • Select the Data Quality Add-On license to identify, report, and resolve the data quality issues for a connector whose data supports data quality, using DQ Rules/functions, Anomaly detection, Reports, and more.
  • Select the Data Access Add-On license that will enforce connector access via OvalEdge with Remote Data Access Management (RDAM) feature-enabled.

Connector Environment

The environment drop-down menu allows you to select the environment configured for the connector from the drop-down list. For example, PROD, or STG (based on the configured items in the OvalEdge configuration for the connector.environment).

The purpose of the environment field is to help you identify which connector is connecting what type of system environment (Production, STG, or QA).

Note: The steps to set up environment variables are explained in the prerequisite section.

Connector Name*

Enter the connector name specified in the Connector Name textbox. It will be a reference to the NFS connection in the OvalEdge application.


Path of the location where files or folders located

Ex: E:\NFSPath

Default Governance Roles*

Users can select a specific user or a  team from the governance roles (Steward, Custodian, Owner) that get assigned for managing the data asset.

Note: The drop-down list displays all the configurable roles (single user or a team) as per the configurations made in the OvalEdge Security | Governance Roles section.

Admin Roles*

Select the required admin roles for this connector.

  • To add Integration Admin Roles, search for or select one or more roles from the Integration Admin options, and then click on the Apply button.
    The responsibility of the Integration Admin includes configuring crawling and profiling settings for the connector, as well as deleting connectors, schemas, or data objects.
  • To add Security and Governance Admin roles, search for or select one or more roles from the list, and then click on the Apply button.
    The security and Governance Admin is responsible for:
    • Configure role permissions for the connector and its associated data objects.
    • Add admins to set permissions for roles on the connector and its associated data objects.
    • Update governance roles.
    • Create custom fields.
    • Develop Service Request templates for the connector.
    • Create Approval workflows for the templates.

No of Archive Objects*

The number of archive objects indicates the number of recent metadata modifications made to a dataset at a remote/source location. By default, the archive objects feature is deactivated. However, users may enable it by clicking the Archive toggle button and specify the number of objects they wish to archive.

Select Bridge

Select option NO Bridge if no bridge is available for the connector.
