Choosing a Benchmark

In deciding to perform a series of tests to evaluate the effectiveness of using solid-state disk drives with the Oracle database system, a test bed that showcased state-of-the-art technology had to be obtained. Texas Memory Systems provided access and sole use to a 64 gigabyte TMS solid state drive, a set of Linux servers and a 64 gigabyte SCSI (and later SATA) disk array. Over the period of May through August of 2004 a series of tests was conducted utilizing version 9.2.0.4 of the Oracle database system and various configurations of the SSD, server and SCSI/SATA drives to evaluate the effectiveness of various combinations.

In reviewing the existing research and applying logic to the results a large performance gain should be seen from placing entire specific types of databases on SSD. Specifically databases that are predominantly read-based such as decision support (DSS) or data warehouses should benefit the most. In order to determine if this is indeed a fact, the TPCH benchmarkwill be used. The TPCH benchmark was designed for DSS testing

The next section will provide an overview of the details behind the TPCH benchmark in order to demonstrate the reasoning for this choice.
