Formula for size of L2ARC

Post by Thomymaster »

Hi


I am searching for the forumla on how to size the L2ARC, but i haven't found anything yet.
Another question, i know that the index for L2ARC is stored in RAM, how much RAM do i then need (it is only a theoretical scenario) per GB of L2ARC?


Best,
Thomas
