Creating a DD Boost user name

Creating a DD Boost user name

An EMC® Data Domain® Boost (DD Boost™) user is an EMC® Data Domain® user. Before setting the DD Boost user access, the username and password must have already been set up on the Data Domain system. vRanger uses the DD Boost user account to connect to the DD Boost repository.

When DD Boost is enabled, a Data Domain OS administrative user can set or change to another DD Boost user. Only one DD Boost user can operate DD Boost at a time.

To set or modify the DD Boost user name:

1	In the DD Boost overview pane located under the Data Management tab, click Add or Modify in the DD Boost User area.

The Set or Modify DD Boost User Name dialog box appears.

2	Do one of the following:

▪	To add a user, click the User Name button.

a	Enter the user name in the DD Boost User Name field.

The user must be configured in the backup application to connect to the Data Domain system.

b	Enter the password twice in the text fields.

c	Select the privilege level for this user: admin or user.

▪	To switch to a user that has already been added, click the Existing User button, and select the user name from the drop-down list.

Click OK.

Creating Storage Units

The EMC® Data Domain® system exposes pre-made disk volumes called storage units to an EMC® Data Domain® Boost (DD Boost™)-enabled backup server. Each Storage Unit is a top-level subdirectory of the /data/col1 directory; there is no hierarchy among Storage Units. When used with vRanger, a DD Boost repository is configured at the Storage Unit level, meaning each DD Boost repository in vRanger equates to exactly one Storage Unit.

 

NOTE: You may also create a Storage Unit from the vRanger UI during the DD Boost repository configuration, or by using the EMC Data Domain Enterprise Manager web console.

1	To create a storage unit on the Data Domain system, enter:

# ddboost storage-unit create storage-unit_name

 

IMPORTANT: Each storage unit name must be unique. For devices running Data Domain OS 5.2 and later, the supported characters are alphanumeric characters and ~!@#$^_+`-={}[],.

2	Repeat the previous step for each DD Boost-enabled Data Domain system.

Configuring distributed segment processing

The distributed segment processing option is configured on the EMC® Data Domain® system and applies to all the backup servers and the EMC® Data Domain® Boost (DD Boost™) Libraries installed on them. For more information, see Distributed segment processing.

The option can be configured using the following command:

# ddboost option set distributed-segment-processing {enabled | disabled}

 

NOTE: Enabling or disabling the distributed segment processing option does not require a restart of the Data Domain file system.

Distributed segment processing is supported with DD Boost Library version 2.2 or later communicating with a Data Domain system that is running Data Domain OS 5.2 or later.

Distributed segment processing is enabled by default on a system initially installed with Data Domain OS 5.2. If a system is upgraded from Data Domain OS 5.0.x to Data Domain OS 5.2 or later, distributed segment processing is left in its previous state.
