About Dell DR Series Systems

The Dell DR Series disk-based data protection appliances optimize utilization with in-line deduplication and compression, and reduce network bandwidth requirements with client-side deduplication processing and deduplicated replication.

These appliances incorporate innovative deduplication and compression technology to help you achieve a data-reduction level up to 15:1. As a result, you can retain more backup data for a longer period in the same footprint.

The Dell DR Series systems use the Rapid Data Access (RDA) Plug-in to integrate its data storage operations with NetVault Backup. This plug-in is automatically installed on the NetVault Backup machines when you install the NetVault Backup Server or Client software.

For more information about Dell DR Series systems, see the Dell DR Series System Administration Guide.

* 
NOTE: The Dell DR Series Systems do not support backups over Wide Area Networks (WAN).

Dell DR Series System prerequisites

Before adding a Dell DR Series system to a NetVault Backup Server, verify that the following requirements are met:

•
Create a storage container: Create the required storage container on the Dell DR Series system. NetVault Backup requires an RDA connection type container. While creating a container, verify that you set the RDA type to RDS.
You must create the container before adding the device to the NetVault Backup Server.
•
Configure the required storage options: On the Dell DR Series system, configure the storage options for the container. For more information about the storage options, see the Dell DR Series System Administration Guide.
•
Configure ports for optimized replication: To perform optimized replication operations across a firewall, configure the following fixed TCP ports on the Dell DR Series system to support RDA replication operations:
•
Port 9920
•
Port 11000
•
Port 10011

Adding a Dell DR Series System

To use a Dell DR Series System for backups and restores, you must first add the device to the NetVault Backup Server. You can use the configuration wizard to add and configure this device.

To add a Dell DR Series System to the NetVault Backup Server:
1
In the Navigation pane, click Guided Configuration, and then on the NetVault Configuration Wizard page, click Add Storage Devices.
— or —
In the Navigation pane, click Manage Devices, and then click Add Device.
2
On the Add Storage Devices page, select the Dell RDA Device option, and click Next.

Option
Description

Network name/IP address

Type the Fully Qualified Domain Name (FQDN) or IP address of the Dell DR Series system.

If the server is unable to resolve the host name, it fails to add the device.

Username

Specify a user account that can be used to log on to the device.

On the Dell DR Series system, only one user account exists, and the user ID for that account is backup_user. You can only change the password for this account; you cannot create an account or delete an existing account.

Password

Type the password for the user account.

LSU

Type the name of the storage container. Verify that the container is created before you add the device. The server does not add the device if the specified container is not available on the device.

Each Dell DR Series system added to NetVault Backup represents a storage container.

Block size

The default block size is 512KiB. The block size cannot be changed for Dell DR Series systems.

Stream Limit

The default value for this setting is 32 streams. This setting applies to all NetVault Backup Servers to which the container is added. If the number of data streams exceeds the defined limit for the container, the Media Manager reports an error (“Device has too many streams”).

You can set the soft stream limit to any value between 1 and 256.

If the container is added to more than one NetVault Backup Server, set the same soft stream limit on all servers.

Force add

If the device is already added to another NetVault Backup Server with the same name, select the Force add check box. This option can be useful if you have performed a disaster recovery to rebuild the NetVault Backup Server.

Click Next to add the device.

After the device is successfully added and initialized, a message is displayed.

NOTE: The Dell DR Series systems support two deduplication modes:
•
Passthrough: When this mode is selected, deduplication processing occurs on the Dell DR Series system. The passthrough mode requires at least 200MB of free memory on the NetVault Backup Client.
•
Dedupe: When this mode is selected, deduplication processing occurs on the NetVault Backup Client. The dedupe mode requires at least 4GB of free memory on the NetVault Backup Client.
