Thanks for the tip Dan.
I've just finished reading Michael Otey's book "Microsoft SQL Server 2008 new Features", and on page 58 he states:-
"Some of the clustering-specific improvements in SQL Server 2008 includes support for an unattended cluster setup. In addition, all of the different services within SQL Server 2008 are fully cluster aware including the
*Relational database engine.
*Analysis Services.
*Integration Services.
*Reporting Services.
*SQL Server Agent.
*Full Text Search.
*Service Broker."
Is this accurate? If so it is the first I've heard of this with regard to SSIS & SSRS.
If SSRS is now cluster aware then I will not need to worry about balancing my two SSRS servers with a load balancing switch.
