Microsoft SQL Server 2008 includes several new and enhanced features that are important for deploying Office SharePoint Server 2007. New and enhanced SQL Server 2008 features are especially relevant for SharePoint deployments in four principal areas:
You can improve Office SharePoint Server performance by implementing the new database backup compression feature in SQL Server 2008. The ability to compress database backups is a significant improvement for Office SharePoint Server users; it enables you to significantly decrease the size of your database backups and shipped logs.
You can improve Office SharePoint Server availability by implementing the new log stream compression feature in SQL Server 2008. One of the performance-limiting factors of database mirroring is network throughput between the principal and mirror servers. SQL Server 2008 supports compression of the log stream, which consists of the inserts, updates, and deletes that are transferred between servers. Log stream compression can help maximize network throughput, especially in environments where network conditions are poor.
You can improve Office SharePoint Server security by using the new Transparent Data Encryption (TDE) feature in SQL Server 2008. TDE enables you to encrypt entire databases and requires no application awareness or modification. TDE encrypts data as it is written to disk and decrypts data as it is read from disk.
You can improve Office SharePoint Server resource management by using SQL Server 2008 Resource Governor. SQL Server Resource Governor enables you to maintain and administer your SQL Server resources, such as CPU and memory. You can use SQL Server Resource Governor to precisely control how your SQL Server resources are allocated. With SQL Server Resource Governor, you can apply thresholds to incoming connections based on assigned criteria.
