There may be situations when you need to mix different Sun Ray servers in a failover group, either based on the hardware architecture, operating system, or Sun Ray Software version. The following list describes which mix of Sun Ray servers are supported in a failover group.
Mixing SPARC-based and x86-based servers running Oracle Solaris in the same failover group is supported.
Mixing servers running Oracle Solaris and Oracle Linux in the same failover group is not supported.
Mixing servers running different versions of Sun Ray Software is supported. However, this is not recommended for long-term use in a production environment. Failover groups that use more than one version of Sun Ray Software will be unable to use all the features provided in the latest releases.
When multiple versions of Sun Ray Software are used in a failover group, the primary server should run the oldest of the versions in use. Otherwise, the presence of a newer feature on the primary server might prevent proper replication of the Sun Ray data store to secondary servers that are running older versions.
If a Sun Ray environment has Unix desktop users, then all the Sun Ray servers in the failover group should run the same version of the operating system. Otherwise, using different GNOME desktop versions from the same home directory can lead to a corrupted desktop state.
