The purpose of this paper is to communicate the numerous successes that have resulted from HALT, HASS, and other environmental testing used by IBM’s Web Server division in Beaverton, Oregon. The engineering and manufacturing facility in Beaverton has been using HALT & HASS techniques for eight years. The first section in this document will familiarize the reader with IBM Beaverton’s product so that they will have a better understanding of the product under test. The second section will describe the environmental tests used during product qualification and manufacturing, which include HALT, HASS, Proof of Screen, and Four-Corners. The third section will discuss the issues uncovered and corrected by utilizing these various techniques on the most recent product generations.
In order to understand the test process better it is important to have some knowledge of the product under test. The Beaverton site designs computer servers based on Intel® processors. The current base product is a fourprocessor system (called a Quad) which can currently be configured with up to 8GB of memory and has 7 PCI expansion slots. Using a technology called the IQ-Link® these Quads can be connected together to form a system with up to 64 processors and 64 GB of memory. The first generation of this product was released in late 1996. The third generation of this architecture, which is based on the Intel® Pentium® III processor, was released in March of 2000.
