SQL Clustering for System Center 2012

Hi,

We are planning to implement System Center 2012 SP1 (SCCM, SCOM, SCVMM) on Windows Server 2012 with two node cluster SQL server 2012 to host database for all the mentioned products to achieve high availability.

There are -

• 3 sites of SCCM 2012 so there will be 3 databases.
• 1 SCOM 2012 server so it will have 3 databases (OpsMgmr, OpsDW, Reportserver)
• 1 SCVMM 2012 server so it will have 1 database.

Like this there will be total 7 databases in SQL 2012 cluster.

So want to understand,

1. Is this recommended to do such configuration?
2. What is the best recommended configuration to host SQL database for all the above products in cluster?
3. Whether to install SQL database with default instances or named instance for each application?
4. As reporting service is not cluster aware then how to install reporting server for all the mentioned products in cluster or way out for this?
5. Are there any issues or challenges if we go with named instance for each application?

Please guide.
