Introduction The purpose of this document is to provide some additional guidelines and recommendations for hardware used in PDMWorks Enterprise installations. There are many variables with respect to hardware sizing and many of them are customer site specific. This paper aims to provide some general guidance as local testing may be required to verify acceptable performance for each customer. This document refers to the PDMWorks Enterprise Storage Calculator which is an Excel Spreadsheet tool that may assist in planning hard drive storage requirements.

Client Minimum Recommended Intel Pentium 4, 1.7GHz 512 MB Windows XP SP2 Microsoft Internet Explorer 6 SP1 Intel Core2 Duo, 1.8GHz 2 GB Windows XP SP2 Microsoft Internet Explorer 6 SP1 PDMWorks Enterprise (CAD Editor) Processor Primary memory (RAM) Operating system Internet browser PDMWorks Enterprise Contributor and PDMWorks Enterprise Viewer Processor Primary memory (RAM) Operating system Internet browser Intel Pentium 4, 1.7GHz 512 MB Windows XP SP2 Microsoft Internet Explorer 6 SP1 Intel Pentium 4, 2.0GHz 1 GB Windows XP SP2 Microsoft Internet Explorer 6 SP1 PDMWorks Enterprise Contributor Web Processor Primary memory (RAM) Operating system Internet browser Intel Pentium 4, 1.7GHz 512 MB Windows XP SP2 Microsoft Internet Explorer 6 SP1 Intel Pentium 4, 2.0GHz 1 GB Windows XP SP2 Microsoft Internet Explorer 6 SP1 Server Minimum Recommended Intel Pentium 4, 1.7GHz 1 GB Windows 2003 Server SP1 Quad Core Intel Xeon, 1,6GHz 2 GB Windows 2003 Server SP1 Quad Core Intel Xeon, 1,6GHz 2 GB Windows 2003 Server SP1 Microsoft SQL Server 2005 SP1 Quad Core Intel Xeon, 2,0GHz 4 GB Windows 2003 Server SP1 Microsoft SQL Server 2005 SP1 Quad Core Intel Xeon, 1,6GHz 1 GB Windows 2003 Server SP1 Internet Information Services (IIS) Quad Core Intel Xeon, 2,0GHz 3 GB Windows 2003 Server SP1 Internet Information Services (IIS) Archive Processor Primary memory (RAM) Operating system Database Processor Primary memory (RAM) Operating system Database Server software Web Processor Primary memory (RAM) Operating system PDMWorks Enterprise Hardware Sizing Guidelines 2 General Hardware Sizing Guidelines There are many variables that affect the proper sizing of hardware for a successful PDMWorks Enterprise implementation including: 1. Network Design a. High Bandwidth b. Low Latency 2. Network Size a. Number of Routers, Switches, Hubs b. Number of Servers, Gateways 3. Work Patterns a. Number of Users – average concurrent use b. Worst Case Use – everyone signs in same time in morning Basic setup involves the following decisions: 1. How many servers? 2. Will servers be Dedicated or Shared Servers? 3. If shared, will they be shared with only PDMWorks Enterprise requirements or with other uses? 4. What size hard drive will we need for storage on the Archive Server? 5. Is budget better spent on faster CPU, faster hard drive I/O or infrastructure? For example: Smaller Installations 1 Server – Combined Use Database Server / Archive Server / Web Server Larger Installations 3 Servers – Dedicated Use Database Server Archive Server Web Server Each server can vary in speed/performance based on hardware and software: • • • • • • Processor Type – i.e. Pentium 4 Processor Speed – i.e. 2.5 Gigahertz RAM – i.e. 8 Gigabytes Core – i.e. Single, Dual, Quad Number of Processors – i.e. 1, 2, 4 Operating System – i.e. Windows 2003 Server Service Pack 1 PDMWorks Enterprise Hardware Sizing Guidelines 3 For example, a network supporting up to 200 PDMWorks Enterprise users might have separate Archive and Database Servers with the following configurations: Database Server Processor CPU Primary memory (RAM) Hard drive (free space) Operating system Internet browser Archive Server Processor CPU Primary memory (RAM) Hard drive (free space) Operating system Internet browser Intel Pentium 4, 3.2 GHz Quad Core 8 GB 20 GB Windows 2003 Server SP1 Internet Information Services (IIS) Microsoft Internet Explorer 5.5 SP2 Intel Pentium 4, 3.2 GHz Single Core 8 GB 250 GB Windows 2003 Server SP1 Internet Information Services (IIS) Microsoft Internet Explorer 5.5 SP2 Hard Drive Storage Guidelines The Archive Server will be responsible for storing all the documents imported into the Vault, all new documents created over the course of the year. It will also store all changes made to documents including the work-in-progress versions as well as the engineering change controlled revisions. Below is an example of a calculator that can be used to determine your initial hardware storage requirements for CAD documents for the first year. Summary In general, the Archive Server which contains the physical files benefits from the fastest hard drive input/output (I/O) speeds while the Database Server which contains the metadata benefits from the fastest CPU. RAM of 4 to 8 GB is recommended. Would consider 4 GB RAM for most cases and put remaining hardware dollars into faster CPU for Database Server and faster hard drives for Archive Server. Multi-Core (Dual, Quad etc.) computers can improve performance and are recommended for larger installations.
