[Pvfs2-developers] Parity striped data

There is no parity in terms of redundancy planned for the filesystem.
However, if you want to look at what we have available in terms of
data striping, look at pvfs2/src/io/description/dist-*.c
The distributions are responsible for determining where and how the
data gets striped.  We have several:   simple-stripe (round robin),
variable-stripes, and 2d-stripes (round robin within groups of
servers).
There is documentation in the pvfs2/doc/design sections regarding
distributions as well.
