With more disk drives over SAS expansion links, you can create more logical groups
of drives. These logical drives using more host channel IDs or LUN numbers.
If a server has multiple data paths to a system, a multipath software might be
necessary.
The two logical drives in the above drawing cannot leverage the full computer power
of the system. You may attach 1 or 2 more expansion enclosures to acquire more
end-to-end performance.
