    Introduction to the Administrator Guide About this Guide This guide explains how to use the Dell DR4000 system to perform data storage operations and manage storage and replication containers. This guide introduces and describes the DR4000 system graphical user interface (GUI) that you can use to manage your backup and replication operations.

    NOTE: Unless otherwise noted, later references to "the system" or "DR4000 system" in this guide are used interchangeably to represent the Dell DR4000 system. The system has a simple installation process with full, intuitive remote setup and management capabilities and is available in the following usable —...

  • Page 12: About The Dr4000 System

    • A graphical user interface (GUI) About the DR4000 System The Dell DR4000 system is a solution designed to reduce your backup data footprint using file-aware and content-aware backup and deduplication operations that optimize storage savings. The system consists of: •...
  • Page 13 For optimal savings, the native data sources need to send data to the DR4000 system in a raw state for ingestion. Block deduplication is not as effective on existing compressed files due to the nature of file compression because its 0s and 1s change from the original format.

  • Page 14: Replication

    Data replication improves fault-tolerance, which improves the reliability of maintaining saved data, and permitting accessibility to the same stored data. The DR4000 system uses an active form of replication that lets you configure a primary-backup scheme in which the system processes data storage requests from a specified source to a specified destination or replica.
  • Page 15 Replicas on the other hand are frequently updated and can quickly lose any historical state. The DR4000 system can be considered as a form of a storage replication process in which the backup and deduplication data is replicated in real-time or via a scheduled window in a network environment.

  • Page 16: Supported File System Protocols

    • If step 1 is not followed correctly, any changes not fully replicated are lost. • During steps 2 and 3, any data that is written to the original DR4000 system source container may be lost. • During step 4, if the data is not fully replicated back before the switch is made, it may be lost.

  • Page 18: Dr4000 System And Data Operations

    DR4000 System and Data Operations Data is stored and resides on the Dell DR4000 system, which is a 2-Rack Unit (RU) appliance, and the system software is pre-installed. The internal drives of the system are configured as a Redundant Array of Independent Disks (RAID) 1 on the RAID Controller, which is considered to be volume 1.

  • Page 19: Setting Up The Dr4000 System

    • An active network is available using Ethernet cables and connections. NOTE: If your DR4000 system is equipped with a 10-GbE NIC, you must use CAT6 copper cabling. NOTE: If your DR4000 system is equipped with a 10-GbE enhanced small form- factor pluggable (SFP+) NIC, you must use Dell-supported SFP+ LC fiber-optic transceivers or twin-axial cabling.
  • Page 20 Adaptive load balancing (ALB), which is the default setting, does not require any special network switch support. Ensure that the data source system must be on the same subnet as the DR4000 system. For more information, see "Configuring Networking Settings" on page 31.

    3 To login using the default password, type St0r@ge! and click Login. NOTE: After resetting the login password to its default and logged in to the DR4000 system, It is recommended for security reasons that you create a new unique login password. Shutting Down the DR4000 System If needed, you can shut down the system by selecting Shutdown in the System Configuration page.

  • Page 46: Rebooting The Dr4000 System

    Configuring Compression Level Settings You can configure the data compression that you want used on all incoming data that is to be backed up and deduplicated by your DR4000 system. NOTE: This is a global compression level setting for your system. Once a compression level setting change is made, the change affects only new incoming data (it is written using the new setting).

  • Page 47: Configuring Active Directory Settings

    The Updated Compression dialog is displayed when the selection is successful. Configuring Active Directory Settings You need to configure this setting if you want your DR4000 system to join a domain that contains a Microsoft Active Directory Service (ADS). To configure the system for a domain with ADS: 1 Select System Configuration Active Directory.

  • Page 48: Configuring Email Alert Settings

    Configuring Email Alert Settings You can create and manage email addresses for recipients in which you want to send DR4000 system email alerts. The Email Alerts page lets you add new, or edit or delete existing recipient email addresses using the corresponding options, and send a test message to the recipient email addresses displayed in the Recipient Email Address pane.

  • Page 49: Sending A Test Message

    4 and 5. Sending a Test Message The DR4000 system provides a capability that lets you send test messages to all of the recipient email addresses. This allows you to ensure that the process for sending system alerts works, and that it reaches all of the email recipients you have configured.

  • Page 50: Configuring Administrator Contact Information

    Configuring Administrator Contact Information You should configure administrator contact information that identifies the person who manages your DR4000 system. To do this, enter contact information for the administrator using the Add Admin option (or edit existing contact information by using the Edit Admin option) on the Email Alerts page options bar.

  • Page 51: Editing Administrator Contact Information

    Configuring Relay Hosts You may need to configure a mail relay host for your DR4000 system if your network email system requires that it have an external mail server. To perform this task, define the mail relay host or edit an existing mail relay host using the Add Relay Host or Edit Relay Host options on the options bar of the Email Alerts page.

  • Page 52: Editing A Relay Host

    Managing System Date and Time Settings If you need to manage date and time settings that are used by your system to synchronize it with other DR4000 systems or clients running in your domain, use the Edit option in the Date and Time page.

  • Page 53: Editing System Date And Time Settings

    NOTE: It is recommended that you use the NTP mode to ensure better replication service operations. Set or modify existing date and time settings for your DR4000 system by using the Edit option in the Date and Time page. Editing System Date and Time Settings To modify the default time and date settings for your DR4000 system: 1 Select System Configuration Date and Time.

  • Page 54: Creating Containers

    The Date and Time page is displayed, and an Enabled NTP service dialog is displayed when successful. Creating Containers After initialization, the DR4000 system contains a default container: backup. Containers function like a shared file system that can be accessed using either (or both) the NFS or CIFS network protocols.

  • Page 55: Managing Dr4000 Storage Operations

    NOTE: The DR4000 system does not support creating container names that start with 0 (zero). In addition, many of the DR4000 system GUI and CLI operations will not work when a container name starts with a 0. Containers function like a shared file system that can be accessed using either (or both) the NFS or CIFS filesystem protocols.
