3-Tier Platform backup systems connectivity overview

  • The 3-Tier Platform Data Protection backup system uses either the 3-Tier Platform top-of-rack or a dedicated pair of network switches for backup traffic.

    Dell Technologies recommends using the 3-Tier platform top-of-rack switches unless there are not enough available ports to support the backup system. In that scenario, allocate a dedicated pair of switches for the backup system.

    With dedicated network switches for the backup system, the 3-Tier Platform network is extended into the backup system network with uplinks. This configuration allows only backup traffic and management traffic to pass. Dell Technologies recommends using Cisco Nexus 93180YC-FX network switches for dedicated data protection backup.

    Dell Technologies recommends that out of band management traffic, in particular iDRAC for PowerProtect Data Domain, connects into the 3-Tier Platform management platform network switches.

    Note: Connect in-band band management interfaces to either the 3-Tier Platform top-of-rack or the dedicated data protection backup network switches.

    Use the following table to determine the number of ports that are required for:

    • OOB management on the management platform network switches
    • In-band management or backup data on the 3-Tier platform or dedicated data protection switches
    Table 98. Ports requirement for OOP or in-bound management interfaces

    The following figure shows the 3-Tier Platform data protection backup network connectivity without dedicated network switches:

    If you are using the recommended top-of-rack network switch for the 3-Tier Platform, breakout connectivity may be required for 10/25 GbE connections. See the Network Layer chapter in this guide for more information.

    Note: A PowerProtect Data Domain HA system has a similar network topology, but it includes a secondary controller. The secondary controller adds an equal number of network connections, as shown in the diagram below.
