The recommended system requirements for the machine running the InfoWorks Workgroup Server are as follows.
The software should be run on a physical or virtual server running a 64-bit Windows Server operating system e.g. Windows Server 2019. Windows Server 2012 and later are supported. There are no UI components, so the Windows Server Desktop Experience is not a requirement. The server may also be run on Windows 10 for experimentation or small-scale use.
At least two processor cores should be available for either a physical or a virtual server.
A minimum of 4GB of RAM should be available. More RAM is recommended if the database size is large. For Standard Workgroup databases, to achieve maximum performance on a physical machine you would have more RAM than the size of the largest network database (.wdb) file on the server, up to about 32GB. Generally, it is recommended to have 16GB of RAM for a physical server. For a virtual server, it would be reasonable to start with 8GB of RAM allocated and monitor memory usage and increase if necessary.
For best performance and reliability, the directory (default C:\ProgramData\Innovyze\SNumbatData) used to store standard databases should local to the machine running the InfoWorks Workgroup Server. It should not be on a file share, except under exceptional circumstances. The use of SSD storage for best performance is recommended.
Overall storage space cannot be easily predicted, as it depends very strongly on the size of the networks to be managed and the presence of other ancillary data (such as ground models) which can increase the size of a database dramatically (tens of GBs). Be prepared to monitor the storage requirements for the database and expand as necessary.
