With more disk drives over the 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 RAID system, a multi-path software is
necessary, e.g., the EonPath driver.
The two logical drives in the above drawing cannot leverage the full computer power
of the system. You may attach 1 or 2 more JBODs to acquire more end-to-end
performance.
