xVelocity and Analysis Services

Along with the SQL Server 2012 launch, Microsoft announced xVelocity in-memory technologies, delivering huge performance improvements for data warehousing and business intelligence. The purpose of this blog post is to clarify what xVelocity means for business intelligence and Analysis Services in particular.

In SQL Server 2008 R2, Microsoft released PowerPivot for Excel which introduced an in-memory analytics engine called VertiPaq.  Vertipaq enables Excel to process hundreds of millions of rows with sub-second response times on desktop hardware.  This engine uses in-memory column-oriented storage and innovative compression techniques to achieve these remarkable results.

In SQL Server 2012, Microsoft has taken the same Vertipaq engine and integrated it into Analysis Services. The results have been staggering with scan rates up to 10s of billions of rows per second on typical server hardware.  Customers who previewed SQL Server 2012 have also experienced compression ratios in excess of 100 times.

In SQL Server 2012, we are re-branding the Vertipaq engine that runs inside PowerPivot and Analysis Services to xVelocity in-memory analytics engine.  This engine is part of the xVelocity family that represents the next generation performance improvements across SQL Server. We will stop using the Vertipaq name and transition the product, documentation and other collateral to use the xVelocity name.
