Deploying HyperScale X Reference Architecture With Bonded 10G Data Protection and Storage Pool Network and 1G Management Network Interface

Updated

HyperScale X Reference Architecture can be setup with bonded Data Protection and Storage Pool interfaces, and a separate Management interface.

Network can be setup using 4-10GigE ports and 1 - 1 GigE port per node as follows:

  • 2 - 1 GigE port for Management network (Routable network with DNS Access)

  • 2 - 10GigE bonded ports for Data Protection (Non-routable network)

  • 2 - 10GigE bonded ports for Storage Pool (Non-routable, private network used for Storage Pool communication)

Note: Management and Data Protection networks should be on 2 different subnets.

This setup requires 3 IP addresses per node. Use the Node Configuration Checklist to collect the information needed to setup the nodes.

Provision the CommServe server with 2 network connections as follows:

  • 1 network connection to the Management network

  • 1 network connection to the Data Protection network

The above networks can be on 1 GB ethernet for this purpose.

Before You Begin

Complete the following before you start:

  • Download and setup the HyperScale X Reference Architecture software, as described in Setting Up the Installation Media.

  • Using ping or any other DNS command / tool, ensure that the DNS entries are available for each of the nodes. Ensure that both the forward and reverse lookups are available for all the IP addresses in the nodes.

  • If you plan to attach the nodes to an existing CommServe, make sure that you are logged in as an user with necessary permissions on the CommServe to install the software. For more information about the permissions needed to setup the node as a client in the CommServe, see User Security Permissions by Feature - Deployment. (If necessary, the deployment permission can be removed for the user after the installation, as this permission check is performed only when the nodes are registered in the CommServe.)

Procedure

  1. Power on the nodes.

    Recommended: Power on 3 un-configured nodes at a time. (If you have more than 3 un-configured nodes, you can add the other nodes later.)

    Tip:

    Press <Alt> + <Ctrl> + <F2> if the login prompt is not displayed.

    Note down the serial number (Hostname) of the node. This will be useful to identify the node during setup.

  2. Login to any one of the nodes using the following default credentials:

    Login: root

    Password: cvadmin

  3. Navigate to the following folder:

    # /opt/commvault/MediaAgent
  4. Execute the following command to generate an input configuration file for the Management network using the routable network:

    ./cvconfignw.py -g <output configuration file path for management network>
  5. Edit the configuration file to add the details of the device and the routable network.

    [network]

    ipaddr =

    gateway =

    nameserver1 =

    nameserver2 =

    nameserver3 =

    netmask =

    device =

    vlanid =

    For example, the entries in this file should be similar to the following:

    [network]

    ipaddr =101.102.103.104

    gateway =101.100.100.100

    nameserver1 =103.99.99.1

    nameserver2 =104.99.99.2

    nameserver3 =

    netmask =255.255.255.0

    device =enpsf2

    vlanid =
  6. Execute the following command to apply the settings for the Management network:

    ./cvconfignw.py -c <config file path>
  7. Setup the bonding for the Data Protection network, using the following command:

    ./cvnwlacpbond.py -c -m <802.3ad,active-backup> -t dp -i <IP for public data protection network> -n <Netmask> -g <Gateway> -d <DNS IP> -nr -f <Interface1> <Interface2>

    For example:

    ./cvnwlacpbond.py -c -m active-backup -t dp -i 172.19.96.54 -n 255.255.252.0 -nr -f enpsf1 enpsf3
  8. Setup the bonding for the Storage Pool network, using the following command:

    ./cvnwlacpbond.py -c -m <802.3ad,active-backup> -t sp -i <IP for private storage pool network> -n <Netmask> -f <Interface1> <Interface2>

    For example:

    ./cvnwlacpbond.py -c -m active-backup -t sp -i 192.168.47.120 -n 255.255.255.0 -f enpsf2 enpsf4
  9. Repeat the above steps to create the network in the other nodes.

  10. From any one of the nodes, create a block using the following command:

    # ./cvavahi.py set_blkid <block id> <node1 serial number> <node2 serial number> <node3 serial number>

    Where:

    <block id> is an unique, unused name for the block.

    <node1 serial number> <node2 serial number> <node3 serial number> is the Hostname, or node serial numbers associated with the nodes. The serial numbers will be displayed in the opening screen when a node is booted.

  11. Open a Web browser from any computer that can connect to the nodes.

  12. Type the IP address associated with the Management network, that was added in the configuration.
