Data domain: How To Connect to a Data Domain System for Administration

PURPOSE:

• This document lists the methods used to connect to a Data Domain for administration.

APPLIES TO:

• All Data Domains
• All Software Releases
• Terminal Software
• SSH
• Telnet
• PS/2
• USB
• KVM

SOLUTION:

Listed below are four methods for connecting to the Data Domain for administration.

Graphical User Interface (UI)

• ​​​​The UI is called Data Domain System Manager (DDSM).
• This is a common method used to connect to the Data Domain from a remote location.
• This connection method is useful for initial setup, viewing real-time performance charts, and is the recommended method for configuring the Virtual Tape Library (VTL) feature.
• This method requires the Data Domain be available on the network.
• To connect to the UI:

1. Launch a web browser.
2. Input the hostname or IP address of the Data Domain to be managed in the address bar of the web browser.

Secure Shell (SSH) (Using Secure Shell (SSH) to log in to a remote Data Domain without giving a password)

• This is a common method used to connect from a remote location. 
• This method allows access to advanced configuration and management features through the Command-Line Interface (CLI).
• SSH requires the Data Domain to be available on the network.

Direct Connection with a USB keyboard and monitor or Keyboard Video Mouse (KVM)

• This method allows access to advanced configuration and management features (using the CLI).
• This is the simplest method of connecting and requires physical access to the system.
• (A PS/2 keyboard is NOT hot pluggable on Legacy Data Domains.)

Serial Cable (Data Domain: Connecting to the Data Domain System with a Serial Cable)

• Connecting with a serial cable is used when it is not possible to directly connect and the network interfaces are unreachable (or are yet to be configured).
• Data Domain Support may require a serial connection to capture the output in a log file for further analysis.
• This method requires a serial (null-modem) cable, compatible terminal software (Microsoft HyperTerminal or PuTTY), and physical access to the system.
• A null-modem serial cable should have been included with the Data Domain.

Once connected, a username and password prompt appears.
