DISK storage pools are prone to fragmentation which FILE stgpools are
not (if you pre-allocate volumes).
DISK storagepools are therefore used as intermediary storage whereas FILE
stgpools are more of a replacement for tape to mitigate tape mount times
and number of mount points, think VTL.
I would hazard a guess that architectural differences are described more
in detail in a redbook, maybe the TSM concepts guide or the TSM technical
guide.
