Hi,
I have read a lot around raid levels and for me the easiest solution would be to extend today solution. As I have understand it takes a lot of power to rebuild an array if it is configured as raid-z2 for example, therefore I want to make it as easy I can.
So far I am using a simple mirror 2+2TB disks with 16GB ECC RAM. My plan is extend this with two more disc at 3 or 4TB.
Would 2x2TB + 4x4TB in a raid 1+0 mirror be to much for 16GB memory? I do not use any special setup with active directory, jails or other heavy tasks. Only a plain ZFS solution here. If I make a calculation around recommended disc/RAM I would only be able to extend to 4x2TB disc without extending RAM to 32GB. Correct? Is this calculation also applicable on a simple mirror as in my case?
Thanks,
