I do harp on about System Center a lot but just because it has become such a good management product suite and I dont think enough people know it!
The products in question:
- System Center Configuration Managed (formally SMS) - this helps with deployment, software update management and config management
- System Center Data Protection Manager - this extends disk-based backup and recovery to Microsoft apps i.e. SQL Server and Exchange
- System Center Virtual Machine Manager - does exactly what it says on the tin. Key thing to knwo is that it manages physical and virtual machines
- System Center Operations Manager 2007 - end to end service solution (particularly great for Windows products)
