There is also dual version of the same expander which has two expander chips so
there are two paths to each drive behind the expander. It is mandatory to use SAS
drives when using the dual expander backplane. This is because the SAS drives
have dual connectivity, therefore enabling the redundancy feature. No SATA drives
should be used in dual expander backplanes.
Internal Cable
A special cable has been designed by Supermicro to connect the two backplanes
mentioned above to the side of the chassis.
