SQL Server Integration Services (SSIS) is not a clustered resource. Connecting to SSIS generally means connecting to any of the SQL Server servers in your cluster environment directly, not to a virtual cluster address. Configuring SSIS for a named BAM instance still involves configuring it against your clustered BAM database instance. The BizTalk install documentation (Multicomputer) also claims that SSIS needs to be installed on the BizTalk Servers. That’s incorrect. You could install SSIS and that’d be good, but I much rather install the management tools, as explained and outlined here.
While talking about BAM I can’t help but to mention an excellent article recently written by Saravana Kumar here.
