Good day ZFS-Discuss,

I am planning to build an array of 30 drives in a RaidZ2 configuration
with two hot spares. However I read on the internet that this was not
ideal.

So I ask those who are more experianced then me, what configuration
would you recommend with ZFS, I would like to have some redundancy but
still keeping as much disk space open for my uses as possible.

I don't want to mirror 15 drives to 15 drives as that would
drastically affect my storage capacity.

There are hundreds of possible combinations of 30 drives.
It really comes down to a trade-off of space vs performance vs RAS.
