VisionR is a platform independent solution. It runs under Windows or Linux. The underlying database can be any one of the major relational databases (RDBMS) available on the market. Each of the generally available browsers (Internet Explorer, Mozilla Firefox, Google Chrome etc.) with JavaScript support can be used as client.

General requirements

Hardware requirements without database

(only VisionR Server with database on another server machine)

Resource Min. requirement Comment
CPU

2 GHz

The more CPUs, the better the performance. VisionR Server runs better on multi-processor servers, because major parts of the code is programmed to run concurrently.
Memory (RAM)

4 GB

VisionR Server can run with good performance on small servers with as less as 500MB. However more memory will let the caches save more data temporarily, which will drastically improve the performance with more users.
Hard disk space

10 GB

VisionR Server requires at least 500MB of free disk space. However more space is required by the documents module, which saves the uploaded files inside the VisionR Server installation directory.

Hardware requirements with database

(VisionR Server and database installed on the same server machine)

Resource Min. requirement Comment
CPU

2 GHz

In case VisionR Server and the Database are installed on the same server, they will share the processor time, which will slow down the overall performance. Multiple processors will definitely improve the performance, because the database and VisionR Server will run concurrently.
Memory (RAM)

8 GB

The minimum memory required by the database is 1GB. However this is implementation dependent - some databases run well with less memory, whereas others my slow down the overall performance. 1GB of memory for the database and 1 GB for VisionR Server is the minimum requirement for a small installation with 10-20 users.
Hard disk space

20 GB

Except the documents module, all other VisionR modules save their data in the database. 1GB of hard disk space for VisionR server including the database is the minimum requirement in case all VisionR modules are installed.
