Immense Disk Space Savings with SQL Server
Database compression dramatically reduces the disk space needed for an SAP NetWeaver system running on SQL Server. As of SQL Server 2008 R2, this uses an improved encoding algorithm for Unicode, also known as Unicode-compression. This results in less storage requirements for SAP Unicode systems. For more information, see this blog. In May 2011, SAP changed the default compression type from ROW to PAGE compression, which led to an additional reduction in the database size.
