Standard Cubes in BW on HANA & In memory usage

Hi,

I have a question regarding Cubes in BW on HANA and memory related to the cube contents.

When we create any standard cube in BW on HANA it creates HANA optimized In memory cube. That means all the data is stored In-Memory.

Now lets consider the scenario where we have BW on HANA and the production system has 2 TB of memory usage.

I want to make system copy of Production to Sandbox with oly 512 GB memory.

In this case is it not possible to take a system copy ?

Is there any way to set these cubes as Standard cubes but not storing data In-Memory, but storing data on SSD?

Regards

Sagar
