3. Configure storage networks.
   

   By default, DeviceManager configures the storage network as the front- and back-end storage networks are converged. You can also modify the configuration file to deploy the front- and back-end storage networks separately.

   • Front- and back-end shared network
     1. Configure the front- and back-end shared network. Table 5 describes related parameters.

        Table 5 Front- and back-end shared network parameters

        Parameter	Description
        Use Configured Storage IP Addresses Only	If you select Yes, the system only allocates configured storage IP addresses in the specified IP address range to the nodes.
        Transmission Protocol	Indicates the transmission protocol used by the network. Possible options are TCP, IB, and RoCE.
        Bond Mode	Indicates the bond mode of the storage network. bond1: active/standby mode bond4: dynamic link aggregation mode NOTE: When Transmission Protocol is set to TCP, bond1 and bond4 are supported. You are advised to select bond4. When Transmission Protocol is set to IB, only bond1 is supported. In this case, bond1 supports the load balancing function. When Transmission Protocol is set to RoCE, bond1 and bond4 are supported. You are advised to select bond4.
        IP Address Range	Indicates the IP address segment of the storage network. NOTE: If you do not select Use Configured Storage IP Addresses Only, the IP addresses in the specified IP address segment cannot be in the same network segment as those of other ports on the node. In the event of using an IPv4 address: A 32-bit IPv4 address is divided into four 8-bit fields that are expressed in dotted decimal notation. Each field of the IPv4 address must be an integer. The value of the leftmost field ranges from 1 to 223 (excluding 127). The values of the other fields range from 0 to 255. An IPv4 address cannot be set to a special address such as a broadcast address. Example: 192.168.1.100 In the event of using an IPv6 address: A 128-bit IPv6 address is divided into eight 16-bit fields. Each 16-bit field consists of four colon-separated hexadecimal numbers. In each 16-bit field, leading zeros can be omitted for simplicity. However, at least one digit must be reserved in each field. To achieve further simplicity, you can use a double colon (::) in place of a series of zeros. A double colon can be used only once in an IPv6 address. It can also represent the neighboring consecutive zeros at the beginning or end of an IPv6 address. An IPv6 address cannot be set to a special one, such as a network address, loopback address, or multicast address. Example: fc00::1234
        Mask/Prefix	When an IPv4 address is used, this parameter indicates the subnet mask of the storage IP address and identifies the subnet to which the IP address belongs. When an IPv6 address is used, this parameter indicates the prefix length of the IPv6 address.
        Port	Indicates the port used by an IP address. Click to go to the Manage Bond Ports page. You can configure a port as required. For details, see Managing Bond Ports.

     2. Click Preview. The system automatically reads the IP addresses configured on the server.
     3. Click Submit.
     4. After the storage network is configured successfully, click Next.
   • Front- and back-end separated networks
     1. Configure the front-end storage network. Table 6 describes related parameters.

        Table 6 Front-end network parameters

        Parameter	Description
        Use Configured Storage IP Addresses Only	If you select Yes, the system only allocates configured storage IP addresses in the specified IP address range to the nodes.
