Planning server-to-server connections
Servers must connect to each other to exchange data, for example to replicate databases and exchange mail. You can create connections between servers across a local area network (LAN) or wide area network (WAN), by using a pass-through server (a server that acts as an intermediary server between a client and its destination), or over the Internet. Create a Server Connection document whenever you need to establish any new or additional server connections. You can modify this document when necessary.
Pass-through servers and hunt groups
Pass-through is a process that runs on a server and establishes connections between the users and servers connected to that server and other servers. Pass-through connections use an intermediary server as a "stepping stone" to connect the two servers.
Example of a pass-through server topology
A pass-through server topology can benefit users and servers on the same network as the pass-through server as well as remote users and servers.

  - Planning server-to-server connections
    Servers must connect to each other to exchange data, for example to replicate databases and exchange mail. You can create connections between servers across a local area network (LAN) or wide area network (WAN), by using a pass-through server (a server that acts as an intermediary server between a client and its destination), or over the Internet. Create a Server Connection document whenever you need to establish any new or additional server connections. You can modify this document when necessary.
    - Remote modem access and server topology
      Servers that are not on the same LAN or WAN can use modem connections to communicate with each other. For example, servers in remote field offices can establish modem connections with servers in a central office to route mail or replicate databases.
    - How a server connects to another server
      A connecting IBM® Domino® server uses the following steps to determine how to connect to a destination server.
    - Replication and server topology
      As the number of IBM® Domino® servers on your network increases, so does the amount of replication required to distribute information across the network. Because replication uses memory and processing time, plan how servers connect to perform replication. If you allow servers to replicate at random, so that a given server replicates a single database with multiple servers, or perhaps replicates different databases with different servers, servers can become so overloaded with replication requests that it interferes with their ability to respond to client requests.
    - Creating a local area network (LAN) connection
      Create a connection document to schedule mail routing to and replication between servers on a LAN.
    - Forcing a server connection to use a specific protocol
      If multiple protocols are available for connecting a source server to a given destination, you can specify which protocol to use by setting the usage priority in a Connection document describing how the source server contacts the destination.
    - Setting up external domain lookups
      An IBM® Notes® user who wants to open a database on a server outside the local IBM Domino® domain, can do so only if there is a connection document in either their local Contacts, or in the Domino Directory on their home server that describes how to reach the target server. To enable Notes users to connect more easily to servers outside of their domain, you can create an External Domain Network Information (EDNI) document in the Domino Directory.
    - Internet connections
      To enable an IBM® Domino® server to connect to another server across the Internet, you must establish Internet access with an Internet Service Provider (ISP) and register an Internet domain name with the ISP -- for example, renovations.com. After you contract Internet service, create Connection documents to instruct the local Domino servers how to contact the target server.
    - Pass-through servers and hunt groups
      Pass-through is a process that runs on a server and establishes connections between the users and servers connected to that server and other servers. Pass-through connections use an intermediary server as a "stepping stone" to connect the two servers.
      - Planning to use pass-through servers
        If you anticipate high traffic through the IBM® Domino® pass-through server, create a dedicated pass-through server.
      - Example of a pass-through server topology
        A pass-through server topology can benefit users and servers on the same network as the pass-through server as well as remote users and servers.
      - Setting up a server as a pass-through server
        Set up a server as a pass-through server to enable users and other servers to route through it to connect to a pass-through destination server.
      - Setting up a server as a pass-through destination
        Set up a server as a pass-through destination to enable users and servers to access it through a pass-through server.
      - Creating a pass-through connection
        After you set up the pass-through and destination servers, you can set up servers to connect to pass-through servers. Creating a pass-through connection enables the server to forward requests from users and other servers to connect to a specified destination server.
    - Planning for modem use
      For an IBM® Domino® server to communicate with a remote Domino server by modem you can install one or more modems on the calling and receiving servers, configure the communication port, and create a network dialup connection from the calling server to the receiving server.
    - Connecting Notes® clients to servers
      After you set up a server to accept inbound connections, it can accept them from both servers and clients. The methods used to establish connections from clients to servers on remote networks are similar to those used when connecting one server to another.
  - Planning directory services
    IBM® Domino® provides a range of directory service features.
  - Planning a mail routing topology
    IBM® Domino® offers you considerable flexibility in configuring your mail system infrastructure, allowing you to use IBM Notes® routing, SMTP routing, or both, for internal and external messages.
  - Planning a cluster
    When planning a cluster, it is important to consider the performance and ability of your hardware. The cluster must have enough CPU power, memory, and disk space to handle the cluster traffic and the number of databases and replicas required.
  - Planning the TCP/IP network
    The default TCP/IP configuration for an IBM® Domino® server is one IP address that is globally bound, meaning that the server listens for connections at the IP addresses of all NICs on the computer. Global binding works as long as the computer does not have more than one IP address offering a service over the same assigned TCP port.
  - Planning the NetBIOS network
    The IBM® Domino® network is compatible with NetBIOS, a set of IBM session-layer LAN services that has evolved into a standard interface that applications use to access transport-layer network protocols.
  - Messaging overview
    The IBM® Domino® mail system has three basic components: Domino mail servers, Domino mail files, and mail clients. The Domino mail server is the backbone of an organization's messaging infrastructure, acting both as an Internet mail server and an IBM Notes® mail server. Domino provides standards-based Internet messaging through its support of the Simple Mail Transfer Protocol (SMTP), Post Office Protocol version 3 (POP3), Internet Message Access Protocol (IMAP), and Multipurpose Internet Mail Extensions (MIME). At the same time, Domino supports Notes mail through the use of Notes routing protocols -- Notes remote procedure calls (NRPC) -- and the Notes rich text message format.

Example of a pass-through server topology

A pass-through server topology can benefit users and servers on the same network as the pass-through server as well as remote users and servers.

For example, the fictional Renovations company has a dedicated pass-through server that functions only to provide workstations and servers with access to destination servers. This server does not contain any databases. The pass-through runs all the protocols that the destination servers run so that users and servers that connect to it have access to the entire system.

Note: Support for direct dialup modem (X.PC) connections is available only in releases of IBM® Lotus® Domino® earlier than release 8.5. You can continue to use Domino® Administrator 8.5 to configure and maintain direct dialup modem support, but only on servers running releases earlier than 8.5.

The example topology requires the following configuration:

Notes® Direct Dialup Connection document on the remote server for connection to pass-through server.
Passthru Connection document on the remote server to specify pass-through.
Connection documents on the remote server for connection to each destination server.
Modified Location document on local IBM® Notes® clients to specify name of pass-through server.
Notes® Direct Dialup Connection document on remote Notes® clients for connection to pass-through.
Passthru Connection documents on remote Notes® clients to specify pass-through connection.
Modified Server documents (to allow appropriate access rights) on pass-through and destination servers.
