Resources to learn about Linux storage?

vDev's, Datasets, zVol's and Volumes vs Disks? Can someone explain all the storage terminology used in linux and how storage things like ACL's are handled versus windows? I have been working in windows enviroments and learning FreeNAS but all this terminology is really throwing me off.

I believe you are wanting to learn about ZFS. It is a BSD/Solaris filesystem but Linux recently has been able to implement it. Here is a good link to get you started.
