[Gluster-devel] afr over unity, or unity over afr?

Hi All,

As we know that unity over afr is similar to RAID10, I wonder if afr
over unity is reasonable or not. Suppose I have a bundle of bricks,
each with different storage volumes. For example:
    Unity1: 100GB 200GB 300GB 400GB
    Unity2: 500GB 500GB
    Unity3: 150GB 250GB 250GB 350GB

Each unity has 1TB of storage, so that I can make an afr over the
three unities to have availability. But is this solution as safe as
unity over afr or not?

Thanks,
Forcey.
