The system should have following components:
Two homogenous Sun Enterprise servers with similar configurations in terms of resources like CPU, memory, and so on. The servers should be configured with cluster interconnect, which is used for maintaining cluster availability, synchronization, and integrity.
The system should be equipped with a set of multihost disks. The multihost disk holds the data (partitions) for a highly available Replication Server. A node can access data on a multihost disk only when it is a current master of the logical host to which the disk belongs.
The system should have Sun Cluster HA software installed, with automatic failover capability. The multihost disks should have unique path names across the system.
For disk failure protection, disk mirroring (not provided by Sybase) should be used.
Logical hosts should be configured. Replication Server runs on a logical host.
Make sure the logical host for the Replication Server has enough disk space in its multihosted disk groups for the partitions, and that any potential master for the logical host has enough memory for the Replication Server.
