Hello,
I´m with some doubts regarding one thing about the management of each HANA instances. At this moment I have one appliance server that has 130Gb of RAM and it has one SAP Hana system (instance) installed (SID Hana: HL1) but today I want to install in the same appliance another SAP Hana system (other instance) called HL2! But my goal is to split the RAM memory between these two Hana systems (HL1 and HL2). During the installation of HL1 I didn´t restrict the maximum memory allocation value and I think I should had done this restriction right here at this stage, but I didn´t... 
I´m talking about this following screen during the installation of SAP Hana system (HL1):
So now, as I said before, I want to install another SAP Hana system (HL2) in the same server/appliance but before doing that I want to know how can I manage the maximum memory allocation that is set to the HL1 instance and if it´s possible to decrease the allocated memory to 75Gb RAM! How can I do that? Is there any parameter that is set to the HL1 instance...!? Can you help me please?
Thank you,
