Dell Data Domain

Application Version and Upgrade Details

Introduction

Dell EMC Data Domain (DD) deduplication storage systems continue to revolutionize disk backup, archiving, and disaster recovery with high-speed, inline deduplication. This innovation continues with Dell EMC’s new generation of mid-sized and large enterprise Data Domain systems powered with a Flash SSD. By consolidating backup and archive data on a Data Domain system, you can reduce storage requirements by up to 55x, making disk cost-effective for onsite retention and highly efficient for network-based replication to disaster recovery sites.

EMC Data Domain Operating System is the intelligence behind EMC Data Domain deduplication storage systems. DD OS powers the industry’s most efficient, scalable, reliable, cloud-ready protection storage platform.

OpsRamp integrates with DELL Data Domain through REST APIs.

Prerequisites

• OpsRamp Classic Gateway 14.0.0 and above.
• OpsRamp Nextgen Gateway 14.0.0 and above.
  Note: OpsRamp recommends using the latest Gateway version for full coverage of recent bug fixes, enhancements, etc..

Application Migration

1. Check for the gateway version as a prerequisite step - classic gateway-12.0.1 and above.
   Notes:
   • You only have to follow these steps when you want to migrate from sdk 1.0 to sdk 2.0.
   • For the first time installation below steps are not required.
2. Disable all configurations associated with sdk 1.0 adaptor integration application.
3. Install and Add the configuration to that sdk 2.0 application.
   Note: refer to Configure and Install the Dell Data Domain Integration & View the Dell Data Domain Details sections of this document.
4. Once all discoveries are completed with the sdk 2.0 application, follow any one of the approaches.

   • Direct uninstallation of the sdk 1.0 adaptor application through the uninstall API with skipDeleteResources=true in the DELETE request.

     End-Point: https://{{host}}/api/v2/tenants/{tenantId}/integrations/installed/{installedIntgId}

     Request Body:

         {
         "uninstallReason": "Test",
         "skipDeleteResources": true
         }

     
     
     (OR)
     
     

   • Delete the configuration one by one through the Delete adaptor config API with the request parameter as skipDeleteResources=true in the DELETE request.

     End-Point: https://{{host}}/api/v2/tenants/{tenantId}/integrations/installed/config/{configId}?skipDeleteResources=true.

   • Finally, uninstall the adapter application through API with skipDeleteResources=true in the DELETE request.

     End-Point: https://{{host}}/api/v2/tenants/{tenantId}/integrations/installed/{installedIntgId}

     Request Body:

             {
         "uninstallReason": "Test",
         "skipDeleteResources": true
     }

     
     

Default Monitoring Configurations

Data Domain application has default Global Device Management Policies, Global Templates, Global Monitors and Global metrics in OpsRamp. Users can customize these default monitoring configurations as per their business use cases by cloning respective global templates and global Device Management Policies. OpsRamp recommends doing this activity before installing the app to avoid noise alerts and data.

1. Default Global Device Management Policies

   OpsRamp has a Global Device Management Policy for each Native Type of Data Domain. You can find those Device Management Policies at Setup > Resources > Device Management Policies, search with suggested names in global scope. Each Device Management Policy follows below naming convention:

   {appName nativeType - version}

   Ex: data-domain Data Domain Backup Server - 2 (i.e, appName = data-domain, nativeType = Data Domain Backup Server, version = 2)

2. Default Global Templates

   OpsRamp has a Global template for each Native Type of Data Domain. You can find those templates at Setup > Monitoring > Templates, search with suggested names in global scope. Each template follows below naming convention:

   {appName nativeType 'Template' - version}

   Ex: data-domain Data Domain Backup Server Template - 2 (i.e, appName = data-domain, nativeType = Data Domain Backup Server, version = 2)

3. Default Global Monitors available

   OpsRamp has a Global Monitors for each Native Type which has monitoring support. You can find those monitors at Setup > Monitoring > Monitors, search with suggested names in global scope. Each Monitors follows below naming convention:

   {monitorKey appName nativeType - version}

   Ex: Data Domain Backup Server Monitor data-domain Data Domain Backup Server 2 (i.e, monitorKey = Data Domain Backup Server Monitor, appName = data-domain, nativeType = Data Domain Backup Server, version = 2)

Configure and Install the Dell Data Domain Integration

1. From All Clients, select a client.
2. Go to Setup > Integrations and Apps.
3. The INSTALLED INTEGRATIONS page, where all the installed applications are displayed.
   Note: If there are no installed applications, it will navigate to the ADD APP page.

4. Click + ADD on the INSTALLED INTEGRATIONS page. The AVAILABLE INTEGRATIONS AND APPS page displays all the available applications along with the newly created application with the version.
   Note: You can even search for the application using the search option available. Also you can use the All Categories option to search.

5. Click ADD in the Dell Data Domain application.
6. In the Configurations page, click + ADD. The Add Configuration page appears.
7. Enter the below mentioned BASIC INFORMATION:

Notes:

• By default Is Secure checkbox is selected.
• Ip Address/Host Name and Port should be accessible from Gateway.
• Select the following:
  • App Failure Notifications: if turned on, you will be notified in case of an application failure that is, Connectivity Exception, Authentication Exception.
  • Event/Alert Polling: enables integrating third party alerts into OpsRamp using further configurations.
• Below are the default values set for:
  • Event/Alert Severity Filter: Provides alerts severity and gets integrated out of all possible alerts.
    • Default Values: CRITICAL, ERROR, WARNING.
    • Possible Values: CRITICAL, ERROR, WARNING.
  • Event/Alert Severity Mapping: possible values of Alert Severity Mapping Filter** configuration property are {“CRITICAL”:“Critical”,“ERROR”:“Critical”,“WARNING”:“Warning”}.

8. Select the below mentioned Custom Attribute:

Note: The custom attribute that you add here will be assigned to all the resources that are created by the integration. You can add a maximum of five custom attributes (key and value pair).

9. In the RESOURCE TYPE section, select:
   • ALL: All the existing and future resources will be discovered.
   • SELECT: You can select one or multiple resources to be discovered.
10. In the DISCOVERY SCHEDULE section, select Recurrence Pattern to add one of the following patterns:
    • Minutes
    • Hourly
    • Daily
    • Weekly
    • Monthly
11. Click ADD.

Now the configuration is saved and displayed on the configurations page after you save it. From the same page, you may Edit and Remove the created configuration.
13. Click Next.
14. In the Installation page, select an existing registered profile, and click FINISH.

The application is now installed and displayed on the INSTALLED INTEGRATION page. Use the search field to find the installed application.

Supported macros keys:

Supported Metrics

Risks, Limitations & Assumptions

• Application can handle Critical/Recovery failure notifications for below two cases when user enables App Failure Notifications in configuration
  • Connectivity Exception
  • Authentication Exception
• Application will not send any duplicate/repeat failure alert notification until the existing critical alert is recovered.
• Application cannot control monitoring pause/resume actions based on above alerts.
• Metrics can be used to monitor Data Domain resources and can generate alerts based on the threshold values.
• Data Domain’s Event/Alert polling will start only if the user enables Event/Alert Polling in configuration.
  • When a severity value which presents in the Event/Alert Severity field occurs, OpsRamp will create an alert based on Event/Alert Severity Filter & Event/Alert Severity mappings of Event/Alert Polling configurations.
  • Default/Possible values of Event/Alert Severity Filter configuration are CRITICAL, ERROR, WARNING.
  • OpsRamp has provided default mappings to map data-domain severity with OpsRamp severities as part of Event/Alert Severity mapping configuration.
  • Users can modify them as per their use-case at any point of time from the application configuration page. Possible OpsRamp Severities are Critical, Warning, Ok, Info.
• No support of showing activity log and applied time.
