Abstract
An apparatus includes a logical space and first and second physical spaces. The apparatus further includes a map in which first successive alternate logical elements of the logical space are mapped to successive adjacent physical elements of the first physical space, and second successive alternate logical elements of the logical space are mapped to successive adjacent physical elements of the second physical space. A control circuit employs the map to substantially concurrently manage storage of data extents into the first and second physical space by routing a first subset of the data extents into the first physical space, routing a second subset of the data extents into the second physical space, and splitting individual extents of a third subset of the data extents into sub-portions, with at least one of the sub-portions being routed to the first physical space and another sub-portion being routed to the second physical space.
