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 Appliance 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 Appliance 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.
The following network names and IP addresses are required for this topology:

Note
If you have more than 3 nodes expand the columns in this table to include all the nodes that you plan to setup.
Similarly. depending on the number of VLANs in your environment, add rows to include the information for all the VLANs.
Cabling and Cable Connections
-
Connect the 10 GbE data protection port from each node to the data protection network.
All data management tasks including backups and restores, are established through the 10GbE data protection ports.
-
Connect the 10 GbE storage pool port from each node to the private storage pool network.
All storage related tasks, including all cluster connectivity for the storage pool network, will be through this 10GbE storage pool port.
-
Connect the 1 GbE IPMI port (BMC Controller) from each node to the IPMI or management or utility network for lights out access.
-
Connect the 1 GbE management port to the management network.
All management related activities, such as connecting to the CommServe server, accessing the DNS server, etc. will be established through the management port.

Supported Network Cables
The network interface cards included with the HyperScale nodes support the use of either optical fiber or direct attach copper (Twinax) cabling.
Note
Each node has 2 dual port 10 GbE adapters with an LC SFP+ transceiver installed in each port. These can be used for 10 GbE fiber cabling or, can be removed for copper Twinax cabling if desired. (RJ45 based 10 GbE NICs are available from the factory.)
The following cable connectors are supported:
For Optical Fiber Connection |
10GBase-SR SFP+ modules are included for all 4 interfaces on each node to support standard or redundant cabling. You will need to provide 10G Base-SR SFP+ modules for your switch and compatible OM3 or OM4 Multi-mode Fiber Cabling. |
|
---|---|---|
For Direct Attach Copper (Twinax) Connections |
Direct Attach Copper cables are not included with an appliance purchase. When purchasing cables, ensure that they meet the following requirements:
|
|
10GBASE-T Support (Copper Twisted Pair) |
10GBASE-T is not supported with the included SFP+ network interface cards. Optional 10GBASE-T network cards are available instead of SFP-based configurations as an option at the time of order placement. Contact your Commvault representative for more information. |
Required Network Cables
You will need several network cables to setup the nodes. Make sure that these cables are available when you setup the nodes.
The following network cables are required per node:
-
2x 1 GbE network cables for the iRMC port and management ports
-
2x 10 GbE network cables for the data protection and storage pool ports
To estimate the total number of network cables required to setup all the nodes, multiply the number of nodes in your cluster with the per node requirement.
For example, if you plan to setup 3 nodes in the cluster you will need the following cables:
-
6x 1 GbE network cables for the iRMC and management ports
-
6x 10 GbE network cables for the data protection and storage pool ports
