What is BI Accelerator Concept?

The BI Accelerator is a novel methodology for increasing the performance of SAP Net Weaver on the basis of the search and classification engine TREX. It is also based on hardware that is preconfigured and is delivered by the hardware partners of SAP. 

It imparts a more significant performance for the OLAP in the IT scenario of an Enterprise Data Warehousing. A BI Acceleration platform built on the OLAP technology with Enterprise-grade security enables companies to achieve unlimited scalability. 

Here is what you should know about the SAP BI Accelerator concept.

The Concept of BI Accelerator

The BI Accelerator is packaged as an appliance to be used with SAP NetWeaver BI. An engine for TREX aggregation that functions to process the data of structured business increases the performance. 

The BI InfoCube’s data gets indexed in the BI Accelerator. It is stored in its storage subsystem in the form of TREX indexes. The BIA indexes get loaded into the memory. They are utilized to provide an answer to the OLAP queries in memory. 

The BI Accelerator minimizes the response time and is helpful for massive data volumes. Thus, customers of SAP NetWeaver BI who use BI Accelerator can benefit from tremendous enhancements in query performance. It is due to in-memory data compression and vertical and horizontal data partitioning. 

The BI Accelerator is provided to the consumer as a preconfigured and pre-installed system on hardware, like a BI Accelerator box. So, the initial configuration and installation processes are already performed by the hardware partner. There is no need for any extra administrative tasks to be executed by the consumer.

BI Accelerator Architecture and Its Relation to the BI System

The BI Accelerator gets installed on a preconfigured lade system. The hosts in the form of server blades in the blade system link to the primary disk storage. It is called a file server. 

A great functionality of the BI Accelerator installation on such a blade system is that the accelerator software gets stored both centrally and on the BI Accelerator data. It means that the software gets installed only one time on the file server. Thus, maintaining it becomes pretty easy. 

Every server blade in which the accelerator runs accesses a single program file. But every blade consists of its very own configuration files. 

A script develops a different subdirectory for every server blade. It copies the files to the subdirectory. The BI Accelerator only supports the 64-bit SuSE Linux operating system. 

Working on the SAP BI Accelerator

You can gauge the working of the accelerator from the following steps:

  • Data gets loaded into the SAP InfoCube from the source system.
  • An index is developed for the Cube and kept within the accelerator appliance. 
  • The accelerator indexes get loaded into memory, where the query gets processed. 
  • At the time of the first query request, index loading into memory occurs automatically. Users can configure the process for preloading at the time of new data.
  • During run time, the query requests are transmitted into the analytic engine, which reroutes it to the BI Accelerator.
  • The query outcomes are sent back to the end-user app.

A BI Accelerator makes way for speedy query processing and load times. It also has the advantage of low maintenance cost. The Accelerator removes the requirement to develop relational aggregates and deal with the OLAP Cache. 

It also has vast potential scalability. A robust BI Acceleration platform delivers instant insights on both cloud and on-premise data lakes. Enterprises can thus ask questions and gain instant solutions to the most pressing problems.
