Ok, that was funny... well, not really, because i did loose a lot of time on it. I have no experience with ASM (Automatic Storage Management) by Oracle, and while a system administrator, i did manage the oracle volumes as filesystems. The raw devices on that time had the 'performance' ...
Well, it has been a long time from my last post, and i'm quite busy with my day-to-day job and other projects that are consuming a lot of my time.
I really like to blog, but right now i really do not have the time i need to write here. ...
DNLC is something that did create a lot of discussions on ZFS mailing list, and is one of that parts that ZFS did not changed, and (at least for me) a ghost. Let me try to explain...

1 - But limits are things that we need to respect in life;
2 - If you have U$10K and do not know how to handle it, U$10M is not the answer for you. Because one cent is overflow in both cases;
