BIAnalytix Tip Summary: Benefits of Parallel Data Warehouse

Data warehouse implementations can grow large and some of the process can drain server resources and take hours to complete. Traditional methods to curb this performance hit include indexing, partitioning, and breaking processes into smaller pieces of work. Several companies offer a new methodology for handling these processes.


Microsoft offers a product called SQL Server 2008 R2 Parallel Data Warehouse. This is essentially partitioning on steroids. The product is a complete hardware software solution that offers multiple servers for parallel processing each with its own disk array. One master control node manages workload by sending requests to multiple processing nodes. Data is partitioned across these multiple processing nodes and the results from a query are returned to the control node to put together. This method of processing tasks across multiple servers with independent resources combines all of the traditional performance improvement methods to provide outstanding performance.

Aside from performance benefits, Microsoft claims an overall cost savings when looking at dollars per terabyte of disk space when compared to a traditional Storage Area Network. Also, because this solution is complete with software and hardware there is an opportunity for cost savings when it comes down to licensing. At the end of the day, the Parallel Data Warehouse can be a cost effective complete solution for processing complex tasks and exposing your data to all of your existing applications.


BIAnalytix is an enterprise class BI system that utilizes technologies such as parallel data warehouses to provide efficient data warehouse processing.
