Connectors

SATA drives are compatible with SAS connectors, but SATA connectors will not accept SAS drives

(Figure B-2). Preventing SAS drives from connecting to a SATA network is important because SATA

drives are, without the intervention of port selectors, single-ported and cannot accommodate the dual-

ported pathways used by SAS drives. These blind-pluggable connectors enable a common topology

including controllers, HBAs, backplanes and both SAS and SATA drives. Such commonality permits

the implementation of dual-domain SAS technology by providing a single standard for all storage

network pathways.
