MSc Dissertation: Reporting Brick - Reducing the cost of performing Business Intelligence with Commodity Hardware


A key component to the success of a Business Intelligence system is getting the requirements right; translating those requirements into code can be a time consuming process when dealing with large volumes of data or if the underlying table structure has a degree of complexity. Using hardware that does not provide responsive query times can mean extended consultancy hours which leads to increased cost or in the case of a fixed budget a narrower project scope.

The cost of server hardware has come down over the past decades, however, in order to get the IO’ps required to perform responsive queries still requires high initial outlay, outlay for a project that may not progress forward should the proof of concept not be successful.

Over the past decade commodity Solid State Devices (SSD) have been making inroads, especially for high end desktop machines used by gamers, enthusiasts and more recently business workstations. Reliability and performance has substantially increased; with SATA 3 appearing more on high end desktop motherboards the full throughput of SSD’s can be realised.

The Reporting Brick concept comes from the initial research performed by Jim Gray et al on Cyberbricks in the late 90’s where they used high capacity SATA hard drives to provide a cost effective solution to prove the scalability of SQL Server 2000 through the TerraServer project.

This project shows commodity kit can be used to great effect within the context of BI, delivering outstanding price-performance.

Research in using GPGPU's for Big Data through Massively Parallel Data Processing


General Purpose Graphic Processing Units are specifically designed to process large volumes of data using many thousands of parallel concurrent threads. With the introduction of PCIe to combat host to device transfer throughput and with PCIe based flash storage to provide very high persisted storage throughput that now bottlenecks on the host CPU, the GPGPU is a perfect candidate for BigData processing.
The project looks in-depth at how best to create synergy between BigData requirements and the massively parallel capabilities and throughput of the GPU cards.
