I'm planning to install an S/4hana demo system. What is the minimum hardware requiremnt?

I know S/4 hana application and HANA DB can be installed together on a single box. What is the h/w requirement in this scenario?

If we add frontend server to the above box, how much additional resources required?

How about gateway and webdispatcher? Are they required? If so, can they be clubbed in the above box?

You can combine the front-end server (gateway) together with the S4 backend.

Based on my experience it's best to deploy it with at least 256 GB of memory. You can give it a try with 128, but this may end up in Out Of Memory exceptions in HANA - this highly depends on the system usage.

Thank you Bartosz.

I've started with 64GB (both front and backend on single box). The installation finished without any issues but OOM issues came up during SPS update. These were resolved by disabling delta merge temporarily and also by taking a restart of application and DB whenever an OOM error occurred. (I had to restart it three times during SPS update)

OOM erros again cameup during client copies and this time the above tricks didn't help. I had to increase the RAM to 128GB. client copy finished without any issue.

I've seen that max RAM utilization was 108GB. So in this scenario (Sandbox)we can say 128GB is minimum RAM required and if you're going to deploy lot of Fiori apps or use it for productive use, much more.




Thanks for letting us know! It confirms my assumption about minimum memory required.

If my answer helped you, please close the question and mark the correct answer.
