The requirements are as follows:

Operating system:  - Windows 64 bit (Server platforms preferred but desktop ones will work too)
                                      - Linux 

Disk Space: This depends on whether application users will be storing documents in the database. If not then 1GB should be enough for the initial 3 to 5 years otherwise please start with 5GB and allow for a growth of 3GB per license per year to be comfortable.

RAM: Requirements depend on the number of simultaneous users expected. A good rule of thumb is to allow 255MB per concurrent user.

For maximum performance, Database engine experts suggest deployment using Solid State Drives and non virtualised OS instances.
