Hello everyone.

 

We are implementing a 2 node HA cluster, using OpenAIS 0.80.3 on SLES 11
HAE. We have found out our service provider is using Cisco switches
which don't support IP multicasting.

 

We have checked and can't see any multicast traffic running on the LAN,
whereas on the virtual test development environment we have, it is.

 

The odd thing is - the cluster is working fine. Can anyone tell me how
it is communicating / establishing quorum etc. without multicast
working? If it has found another communication route what are the
reliability and performance implications?

 

Regards,

Darren Mansell
