End Device Frame Buffering
Using the 12Gb/s SAS technology, including End Device Frame Buffering (EDFB)
technology, the ROC and expander are designed to help ease the industry’s transition

speeds while using existing 6Gb/s drives and backplane infrastructure. This
technology allows the expander to perform aggregation, essentially allowing two
devices to share one port on the expander.
