HP 418800-B21 Redundancy in enterprise storage networks using dual domain SAS - Page 12

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 dualported 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. Figure B-2.
