CentOS - Mar 2013 - what is "single spanned virtual disk" on RAID10????

We have DELL R910 with H800 adapter in it.  several MD1220 connect to H800.

Since MD1220 have 24 hard disks in it.  When I configured RAID10, there is a
choice call 'single spanned virtual disk"  (22 disks).

Can anyone tell me how "single spanned virtual disk" work?

Any document relate to it?

Thanks.

Not to be a troll, but that's probably a question better suited for the
Dell and/or PowerEdge list.
