Hi. We have a critical solution working. we need to create an environment that acomplish with this:
1. It must be failover.
2. It must take advantage from infra we already have.
I´ve read abot HPC 2008. It seems good, What can you tell me about it? The applications i´m talking about developed in .Net 2005 over MSSQL 2008. My intention is to install SQL with HPC and in a Virtual Machine ruuning in this cluster and IIS server.
I would suggest that you take a look through http://technet.microsoft.com/en-us/library/ee783547(WS.10).aspx - the documentation in there covers a lot of ground. It is hard to give you a more complete answer since your initial question and statement of requirements is somewhat vague.
It is possible to run HPC 2008 R2 in a failover setup and you can leverage existing infrastructure through the cluster of workstations functionality and you can also run VM's.
