The following are the minimum system requirements for WebCenter 21.03. Exceeding these requirements will in most cases lead to a performance increase. Running WebCenter on a system that does not meet these requirements is not supported.
About WebCenter Server System Requirements
WebCenter employs three distinct servers:
- a Web Server,
- an Application Server and
- a Database Server.
It also has a FileStore and an On-Board Graphics Engine (OBGE), which is used to generate view data.
Entry Level (two servers)
WebCenter Entry Level requirements are based on activity with 10 concurrent users active at any time and less than 100 users in the system but works well up to 30 concurrent users for most installations (results may vary depending on application usage and could result in requiring the Advanced Level Setup).
In the Entry Level setup, the installation of the Application Server and Database Server is combined onto a single machine. The OBGE and the FileStore are on the Application Server. For security reasons, the Web Server is always on its own dedicated server and placed in a demilitarised zone (
We recommend the use of hardware firewalls for creating the
Advanced Level (three or more servers)
When the WebCenter Entry Level cannot meet the load requirements of the system, it is possible to scale the system. For security reasons, the Web Server will always be a separate server in a
DMZ. Each of the other WebCenter components (Application Server, Database Server, FileStore and OBGE) can be offloaded onto separate machines in different combinations.
For Advanced Level installations, it is recommended to choose the Advanced Installer option to allow more custom configuration, and to choose Extra Large for the Deployment Size.

100 GB, should be expandable as data storage grows with usage.
For WebCenter to perform according to expectations, the FileStore needs to be on Windows file servers. We recommend to use Windows Server 2008 R2, Windows Server 2012 or Windows Server 2012 R2 and Windows Server 2016 as file server (but ReFS data volumes are not supported yet).
As only Windows file servers are supported, Mac OS X or Unix/Linux (CIFS/SMB or NFS) data servers for instance are not supported (including many Network Attached Storage units).

This includes all service packs.
The shipped version of SQL is bound to limitations, more information can be found on the Microsoft website.
This includes all service packs.
If you install the Global Vision extension on the OBGE, the OBGE needs to be separated from the WebCenter Application Server.
If you install the additional Automation Engine Processor module license for WebCenter, the OBGE needs to be separated from the WebCenter Application Server.
If using Automation Engine 18.0.1, 18.0, or 16.1.1 to connect to WebCenter for outside-LAN approval feedback, you need to install a hotfix on Automation Engine for this functionality to still work after updating to WebCenter 20.1.
The hotfixes can be downloaded from mysoftware.esko.com:
|Automation Engine version||Hotfix name|
Older versions of Automation Engine are not officially supported.

Scaling Recommended System Requirements
WebCenter can be scaled up to 500 concurrent users in single installation. These limits are set based on our flied experience and internal lab test. This limit will be changed to higher numbers as and when we learn more.
In general, high speed hard drives (both throughput and seek time; e.g.:
SSD) will work beneficial, but are not a requirement. Write speed should not be traded off for read performance as both are of importance to the application. Try to avoid large seek times (e.g.: due to
SAN), also for the FileStore, as this will make performance degrade quickly.
For the Database Server, in general, the higher the read and write speed, the lower will be the seek time, the better everything will work. For very large installations, having the transaction log, temporary DB and actual DB on an individual
SSD can be considered.
OBGE, it is possible to run multiple preview generation process in parallel if that is enabled in your configuration.
