Print Friendly and PDF Follow

The following hardware and software items are needed to run the ILLiad system effectively. They are not provided as part of the licensing of ILLiad or as part of the service contract with Atlas Systems.

These requirements ensure that ILLiad will perform well for you and have all the necessary features available to support functionality. While ILLiad may run in unsupported environments with older than the minimum required software and hardware, we cannot guarantee operation.

Server Requirements

You can install Windows on a physical server or virtual server as long as it meets the hardware and software requirements.

The following hardware and software are compatible with the ILLiad server:

  • Intel Xeon 3Ghz or greater processor (recommended)
  • Intel Pentium 4 2Ghz or greater processor (minimum)

More RAM will substantially increase system performance

  • 8GB of RAM (recommended)
  • 4 GB of RAM (minimum)
Hard Drive
  • 72GB high speed hard drive (recommended)
  • 36GB hard drive (minimum)
  • Compatible backup device
Windows Server
  • Windows Server 2022 (Desktop Experience only)
  • Windows Server 2019 (Desktop Experience only)

*ILLiad requires the SQL Server Database Engine but does not use Analysis Services, Reporting Services, or Integration Serves. Mixed mode authentication is also required.

**The SQL Server Native Client is installed as part of the client & server installation and is also part of the server update process, so no action is typically required. However, installing or updating to SQL Server Management Studio (SSMS) v19 will remove the SQL Server Native Client from the server, at which point this component will need to be reinstalled.
