How Savepoint store in persistent storage works ?


Hi to all,

I have read that SAP HANA is ACID compatible. And will not lose data if power goes off.

This is because changed pages and log are written in save point and written to persistent storage.

1. But where this stored in RAM or some kind of DISK ?.

As per understanding that once power off all RAM data will go off.

2. Then how save point/ log gets back the data into RAM ?.

Please can any one explain above 2 point ,if i am wrongly understood.

I shall be thankful to you for this.
