Celerra File systems

[vptl]

Anyone can explain how the slice volume,disk volume,volume,strip volume,meta volume and file systems are related....
is it similer to sd,plex,volume,file system concept of veritas ? if so why do we have disk volume on top of disk sslice ?
Are the disk slice and disk volume diffrent ?
Are the slice and slice volume are diffrent ?
Can you use either of slice or disk volume to make meta volume ?
What is the easy way to map file system top physical disk location ...I know toooo many qs...

thanks,
