Suse cluster for - Disaster recovery.

We have a two node active passive suse heart beat cluster. Storage using is SUN6140 with os level lun mirroring. Applications are oracle with sap.

I need a DR solution for this setup.

Can i able to add one more node in existing cluster in the DR site ??

how we oslevel mirroring works in DR setup

Re: Suse cluster for - Disaster recovery.

There are different configurations for a DR solution.

You can have a "spare" system on the DR site replicating only the "data". In this case, the OS level mirroring is not a problem as you already have one up and running.

What you do have to find is a solution to replicate the data between the sites.

Can you provide more information about your infrastructure, like storage systems, link to the remote site, etc.

Something for you to think about -- what will you do if the Sun6140 is the component that dies?

Re: Suse cluster for - Disaster recovery.


if you are using the SLES-HAE there are predefined resources classes where you can use things like DRDB or OSFS2 cloned disksets to replicate to another node. - Allowing you a moderated active/active configurations as well which you can tailor for use with your app.

I notice that you are using oracle. Its worth talking with oracle/novell about SLES-High Availability Extension, as its got a load of Oracle specific utilities for you to use in it.

Hope that helps, please assign points if you found this useful.

The other option is to do host-based replication. Q - what software solution can be used to do this host-based replication via IP link 10Mbps?
