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.

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

separate Archive and Database Servers with the following configurations:

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.
