Deploying a Virtual Data Domain

EMC have taken a proven purpose built backup appliance and created a software defined backup solution which can utilise your existing hardware. The virtual Data Domain keeps all the core functionality of its physical counterpart, such as DD Boost, inline deduplication and replication. At the time of writing the virtual Data Domain is intended for use in remote offices, scales up to 16 TB per appliance, and is quick and easy to deploy.

Requirements

  • For this install we will be using Data Domain Virtual Edition 2.0 which requires vSphere 5.1, 5.5 or 6.0, and the use of 1.6GHZ or higher processors.
  • The virtual machine uses 260 GB for system disks, if thick provisioned, plus whatever you allocate for the file system (minimum of 200 GB). It also requires between 2 and 4 vCPU and between 6 and 16 GB RAM, dependent on the amount of storage you intend to present.
  • The download comes with an evaluation license for non-production environments using up to 0.5 TB of storage, for full licensing you will need to contact your EMC account manager.

Installation

Download the EMC Data Domain Virtual Edition. Unzip the contents to access the OVA file and license file.

In the vSphere client or web portal select deploy OVF template and browse to your unzipped OVA file. The process is pretty standard you will enter a name, select a destination datastore and VLAN, etc. Take note on the configuration page as the selected specification should be correct for the amount of storage capacity you intend to use. Do not tick the box to power on after deployment.

After the virtual machine has been deployed you need to add an additional disk or disks for the file system, those already configured (250GB and 10GB) are system disks. Power on the virtual machine, open a console and log in with the default username and password: sysadmin changeme.

When prompted change the admin password, you will be asked if you want to configure the system using a GUI wizard, all this does is open a wizard when you first log in to the Data Domain web interface. If you have no previous experience with Data Domains then you may wish to type yes so you can be guided through the process, otherwise type no and hit enter (all settings in the wizard can still be configured using the GUI menu options).

Type yes to configure the network and follow the onscreen prompts to enable and configure the network settings for your environment. Type no to configuring eLicenses and system configuration, we will pick these up later.

When prompted select to save the settings. Configuration is now complete; type logoff and verify you can ping the configured IP address from your client machine.

Browse to the Data Domain web interface at http:// and log in using the sysadmin account. You will be prompted to provide a license, browse to the .lic file which was unzipped from the download earlier and click Apply.

Once logged in you will notice the web interface is the same as a physical Data Domain. If you opted for the GUI wizard this will now appear, otherwise you can setup the appliance as normal.

  • Browse to Administration > Settings and configure the mail server, time and date, system properties and SNMP if required (alerts are setup separately under Health > Alerts).
  • Broswe to Data Management > File System to create the file system. You can configure quotas and snapshots here too if required.
  • Browse to Protocols > DD Boost to configure DD Boost. You can also configure CIFS and NFS.

When configuring the file system if you receive the error ‘the file system cannot be created because no storage was detected’ then you should ensure an additional disk or disks were added earlier. If these were added after powering the virtual machine on then reboot the virtual machine. To check the listed devices use ‘disk show hardware’ on the console.
