Partitioned Domino® servers and IP addresses

When you set up an HCL Domino® partitioned server, it is usually best to assign a separate IP address to each partition and use a separate NIC for each. Using a separate NIC for each address can make the computer's I/O much faster.

Domino® is designed to listen for TCP/IP connections on all NICs in a computer system. If more than one partition is hosting the same service (NRPC, SMTP, POP3, IMAP, LDAP, or HTTP), fine-tune which partitions listen for which connections by associating each service's TCP port with a specific IP address.

As an alternative to using a separate NIC for each IP address, you can use a single NIC and still assign a separate IP address to each partition.

If you are unable to assign a separate IP address to each partition, you can use port mapping.

Note: As an alternative to port mapping, you can use port address translation (PAT), in which a firewall redirects the TCP port connection to a different TCP port. Both port mapping and PAT require advanced skills to implement correctly.
