The busy people at SQLCAT have released another whitepaper, this time on SQL Server 2008 Failover Clustering. This is quite a long document at 175 pages, but it is packed with useful information.
Failover clustering is a tested and reliable technology for high availability, although it does have a single point of failure in the shared storage. We used to combine failover clustering with database mirroring, with very good results at NewsGator.
