Where can I find Storage Pools details?

I am trying to find out how MaprFS stores data (Detailed documentation would be helpful).

To simplify this let's assume that I have a 2GB file. When I write this to disk, what I think happens is that the file is split into 8 x 256MB chucks.
Each chunk is then stripped within a storage pool (RAID-0 style) but all files be saved within the same storage pool.

Also, each chuck is going to be replicated according to replication settings

Questions:

 1. Are my above statement correct?
 2. What is the strip size? (8KB?)
 3. Is each file is written to a single storage pool?
 4. Is there a storage pool correlation among servers? (My guess is no!)
 5. At what level does the compression takes place? (Chunk level?)
 6. Will volumes use all storage pools by default?
