There are a number of recommendations for calculating sizing. You will need:
- Four high clocked cores per engine, with between 4 GB and 6 GB RAM. If you find that you need more power, it is better to add another engine instance with a similar specification than to upgrade the hardware. The reason for this is that Microsoft Office is not very scalable.
- Between 10 GB and 15 GB of free space. Storage is not that important, but if you have lots of large files, you should make sure that creating temporary copies of those files will not slow the system down.
- Gigabit Ethernet.
- At least one CPU for each concurrent transformation that is expected to be processed by the engine.
