Installing Sametime Gateway Servers in a cluster
Install a cluster of IBM® Sametime® Gateway servers in a network deployment.
About this task
Sametime Gateway Server supports cluster members on multiple nodes across many nodes in a cell, with nodes either coexisting on the same computer, or running on separate systems. A network deployment is made up of a deployment manager, which manages the cell, SIP, and XMPP proxy servers, a primary node, and, if needed, one or more secondary nodes.
Note
the following restrictions:
- All of the cluster components (deployment manager, nodes, proxies) must be deployed in the same LAN.
- Configure WebSphere® Application Server Network Deployment with a single subnet for network traffic. You can use one Network interface card (NIC) on a physical computer or logical partition (LPAR). You can also reference a single Domain name system (DNS) server in the network configuration for the physical computer or LPAR.
- Deploying components over a WAN is not supported.
- Placing a firewall between two components is not supported (even if the firewall is configured to allow the relevant traffic).
- When deploying a load balancer in front of a cluster's WebSphere SIP proxy servers, the load balancer must be able to communicate with the proxy servers in Layer 2, using MAC forwarding. IP forwarding (Layer 3) is not supported.
