Manage physical memory capacity in Azure Stack Hub
To increase the total available memory capacity in Azure Stack Hub, you can add more memory. In Azure Stack Hub, your physical server is also referred to as a scale unit node. All scale unit nodes that are members of a single scale unit must have the same amount of memory.
Before you continue, consult your hardware manufacturer's documentation to see if your manufacturer supports a physical memory upgrade. Your OEM hardware vendor support contract may require that the vendor perform the physical server rack placement and the device firmware update.
