VLAN Topology for HyperScale X Reference Architecture

This topology combines VLAN topology with a 1 GbE management interface.

  • This allows multiple tagged VLANs to connect to the appliance using the data protection interface. This allows connection to multiple non-routable networks, to avoid sending backup traffic through a router or firewall.

  • The management interface can be used to route management traffic to leverage one of the built-in 1 GbE copper interfaces for management traffic and will require additional cabling.

In this topology, each node requires the following connections:

  • 1 - 10 GbE port for data protection which will connect to multiple VLANs to transfer data to and from the clients being protected and connect to the CommServe server. This will include connections to:

    • 2 or more VLAN IDs

    • 2 or more IP addresses based on the number of VLANs

  • 1 - 10 GbE port for storage pool which is a dedicated private network, used for communication and replication between the HyperScale nodes.

    VLAN interfaces cannot be configured on the storage pool interface.

  • 1 - 1 GbE port for management network, which is used exclusively for all management related communication, such as connecting to the CommServe server, accessing the DNS server, etc.

Note

VLANs connects multiple tagged VLANs directly to the HyperScale X Reference Architecture nodes over a single physical connection. This is typically used to connect directly to different networks to avoid traversing routers or firewalls that can become a bottleneck, or to connect to isolated networks. Combine the VLAN topology with a Management network if the HyperScale X Reference Architecture nodes are located in an isolated backup network. This setup does not provide network redundancy and hence should be combined with the bonded VLAN configurations.

Network Requirements

In this topology, the number of IP addresses required depends on the number of VLANs. For example, if you have 3 VLANs, 10, 20 and 30, you will require 3 IP addresses per node, as follows:

  • 1 - 10 GbE data protection port connected to the VLAN IP addresses for each of the VLANs used for data protection.

    Out of the available VLANs, one network should be routable and the other network(s) must be non-routable. The routable network will be used for CommServe server registration, in addition to data protection operations. All the other VLANs will be used exclusively for data protection operations.

  • 1 - 10 GbE port for the storage pool which is a dedicated private network, used for communication and replication between the HyperScale nodes. This requires a corresponding IP address for the storage pool network.

  • 1 – 1 GbE port for the management network, which is connected to a routable network with DNS access. This requires a corresponding IP address for the management network.

    Note

    Data Protection, storage pool and management networks MUST be on separate subnets.
