Was that a memory mapped hard disk?  BTRFS does what lvm does, combine disks. With btrfs you can simply make the filesystem span multiple disks without having any layer underneath to abstract the partitions/disks.

It's not a new idea, but what it does offer is doing this as part of the filesystem, instead of having to use a raid/volume manager.
