SQL Server high-availability and disaster-recovery architectures

I want to share with you a new whitepaper written by Paul S. Randal that describes the five most commonly deployed high-availability and disaster-recovery architectures deployed by customers, along with a case study of each. It covers:

Failover Clustering for High Availability with Database Mirroring for Disaster Recovery
Database Mirroring for High Availability and Disaster Recovery
Geo-Clustering for High Availability and Disaster Recovery
Failover Clustering for High Availability Combined with SAN-Based Replication for Disaster Recovery
Peer-to-Peer Replication for High Availability and Disaster Recovery

You can download it from http://download.microsoft.com/download/5/B/D/5BD13FFA-5E34-4AE1-9AA0-C6E6951B8FC8/SQL%20Server%202008%20R2%20High%20Availability%20Architecture%20White%20Paper.docx

Need to consolidate SQL Server?

If you need to consolidate your SQL Server instances, a paper you must read is the “SQL Server Consolidation Guidance” avaialable at http://msdn.microsoft.com/en-us/library/ee819082.aspx

If you are thinking in virtualization please considerer the newer processors is second-level address translation (SLAT), also known as nested paging. AMD refers to this technology as NPT, and Intel calls this EPT in their respective processors. The following graph (taken from the Consolidation Guidance) shows how application workload can benefit from the use of SLAT to achieve linear scale and improved performance.
