RAID-10 explicitly defined drive pairs?

	Hello, Linux RAID gurus,

I have a new server with two identical external disk shelves (22 drives each),
which will be connected to the server with a pair of SAS cables.
I want to use RAID-10 on these disks, but I want it to be configured
so that the data will always be mirrored between the shelves.
I.e. I want to be able to overcome complete failure of a single shelf.

	Is there any way how to tell mdadm explicitly how to set up
the pairs of mirrored drives inside a RAID-10 volume?

	Thanks,

-Yenya
