CLUSTERS

Using an IP sprayer with Domino for LDAP failover
You can cluster LDAP servers to increase the availability of data. One way to do that is to create a Domino cluster of LDAP servers, and then use an IP sprayer to direct client requests.

In the following figure, there are two LDAP servers in an IBM® Lotus® Domino™ cluster. Both servers contain a replica of the LDAP directory. An IP sprayer directs an LDAP client to LDAP Server 1. If LDAP Server 1 is not available, the IP sprayer directs the client to LDAP Server 2.

IP sprayer for LDAP failover

You can also use an operating system cluster for LDAP failover.

If you are using directory assistance, you can use either directory assistance failover or Domino failover.
