      The DSS cluster name must follow the limit of 256 characters.

    • CBR node host name

    • CBR node key

    Note:

    To obtain this node key run the cat /etc/ssh/ssh_host_rsa_key.pub |awk '{print $2}' |base64 -d |sha256sum |awk '{print $1}' command. This node key must contain 64 characters.

  6. Click Next.
  7. On the DSS cluster nodes tab, add one or more cluster nodes. You can add multiple nodes either in chip format or comma separated.

    Note:

    In case of duplicate entry, only one is entry is considered.

    • DSS minimum storage per backup node

      The minimum storage requirement for Data optimization on data stage server.

    • Concurrent compaction

      The maximum number of compactions that can run concurrently.

    • Loader memory size

      The heap memory size for Cassandra table loader.

    • Concurrent transfer
