In a 7440/8440 you have upto 4 Controller with 2 x 2 SAS bus's. One SAS Bus is supporting upto 120 Devices.

How you can connect upto 2 x 480=960 HDs?

Think about the fanout-expander to edge expander topology.

See for example http://www.scsita.org/serial-storage-wire/2005/02/sas-expanders-scalable-by-design.html


Hope this helps!
