4. Expand a Bow Pod64 to a larger Bow Pod system
Bow Pod systems that are larger than Bow Pod64 are built from multiple Bow Pod64 systems.
So, in order to expand to a system larger than a Bow Pod64, you need to:
- Determine how many additional Bow Pod64 systems, servers, cables and switches you will need - for help with this you can contact Graphcore support. 
- Build the extra Bow Pod64 systems that you require for your target system following the instructions in the Bow Pod64 Reference Design: Build and Test Guide. 
- Connect the Bow Pod64 systems together and test that all the components are working, then install the required software on the management server(s) - for help with this contact Graphcore support.
