Basic Topology for HyperScale X Appliance

Basic topology provides the minimum required connections per node for the data protection and storage pool networks.

In this topology, each node requires connections to 2 separate network as follows:

  • 1 - 10 GbE port for data protection network, which transfers data to and from the clients being protected and connect to the CommServe server.

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

Note

Basic topology is the easiest option to setup and deploy. However, this setup does not provide network redundancy, and is recommended only for non-production use, or if you do not have the required port availability for redundant connections.

Network Requirements

In this topology, each node requires the following connections:

  • 1 - 10 GbE port for the data protection network,which transfers data to and from the clients. This requires a corresponding IP address for the data protection network.

  • 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.

    Note

    Data protection and storage pool networks MUST be on two 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.

Cabling and Cable Connections

  1. 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.

  2. 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.

  3. Connect the 1 GbE IPMI port (BMC Controller) from each node to the IPMI or management or utility network for lights out access.

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:

  • Any SFP+ passive or active limiting direct attach copper cable, that complies with the SFF-8431 v4.1 and SFF-8472 v10.4 specifications.

  • Maximum cable length for passive cables is 7 meters.

Remote Installation Assistance (RIA) Program (2)

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:

  • 1x 1 GbE network cable for the iRMC port

  • 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:

  • 3x 1 GbE network cables for the iRMC ports

  • 6x 10 GbE network cables for the data protection and storage pool ports
