Connecting the Web Servers

  • Article

The following procedure describes how to connect and configure the network adapters on each Web server during deployment. Each Web server uses two network adapters: one for communicating with clients on the Internet, the other for communicating with servers in the database tier.

The following figure illustrates a sample network configuration for a Web cluster consisting of three Web servers.

Sample Web cluster network configuration

To connect the Web servers

  1. Connect the front-end network adapter (for communicating with clients on the Internet) to a hub that is connected to the external firewall.
  2. In the Internet Protocol (TCP/IP) Properties of this adapter, enter the IP address, Subnet mask, and Default gateway. The IP address entered in this step specifies the dedicated IP address for this server.
  3. Connect the back-end network adapter (for communicating with back-end databases) to a hub that is connected to an internal firewall (separating the Web tier from the database tier).
  4. In the Internet Protocol (TCP/IP) Properties of this adapter, enter the IP address, Subnet mask, and leave the Default gateway blank.
  5. Repeat steps 1-4 for each Web server using different IP addresses.

Network configuration is complete on the Web servers. To install Network Load Balancing (NLB), see Clustering the Web Servers.
