Geographical Locations for primary and adoptive nodes

[Guru Prasanna]

Hi,

I am new to MC Service guard. I have a question. Can I have primary and adpotive
nodes of an HA cluster located in geographically two different locations, but
they are on the same WAN? For example, can I have an HA cluster where one node (say primary) is located in US and one adoptive node located in Europe, but they are on the same WAN? Basically, I want to achieve geographical independence on the hot and the standby host. Does MC service guard support this?

Regards,
Guru

Hi,

Wide Area architectures use leased, switched networks. This architecture is currently not supported by MC/ServiceGuard due to the requirement that heartbeat networks use a single IP subnet.

The major issue with this architecture is the bandwidth of the link and the data replication requirements.

For more information, read this document at:

Hope this helps. Regards.
