Yes anthony, I indeed had a look at that. My conclusion is that there are 2 ways

* configure SSIS as a cluster resource

or

* change SSIS config (.ini/xml) file and make SSIS run even after failover

And that "configure SSIS as a cluster resource" is not recommended by Microsoft and they are vouching for Config file change option. So i too would want to chose "config file change" option.

went through http://dougbert.com/blog/post/ssis-and-clustering-what-you-should-do-instead.aspx

The way i see it, in a 2 node cluster, installing SSIS on both nodes and making the ini/xml changes in both nodes (to add another set of <Folder xsi:type="SqlServerFolder"> in Top Folder in the MsDTSSrvr.ini.xml file in both nodes) would be enough to make SSIS to run even after faiover
