Figure 11 shows a topology for connecting one external port on the two-port controller to a storage
enclosure containing up to ten SFF SAS or SATA drives. This single controller port incorporates four
lanes for a total maximum throughput of 2400 MB/s. The storage enclosure contains an internal 36-
port expander that supports cascading an additional enclosure in a 1+1 configuration containing up
to 25 SFF SAS or SATA drives.
