One server comes with 100GB of storage space. Resources stored in the storage space, including Windows OS and other software (eg. the BIM Server/BIMcloud installation) use this space (usually ~20-30 GB) and all remaining available storage space is for your project data.
In the future if your firm needs more space there is an additional monthly charge. Amazon charges $0.10/GB/month and we will pass that cost on to you without markup. If you feel your firm will need more space we can easily accommodate your request without any downtime. If you have any projects on your BIM Server that are not in production anymore, we recommend you archive the project (save the project as a SOLO project in ArchiCAD) and remove the project from the BIM Server to free-up hard drive space.
