How does Serial ATA and Serial Attached SCSI work together?
Serial Attached SCSI compliments Serial ATA by adding device addressing, and offers higher reliability and data availability services, along with logical SCSI compatibility. It will continue to enhance these metrics as the specification evolves, including increased device support and better cabling distances. Serial ATA is targeted at cost-sensitive non-mission critical server and storage environments. Most importantly, these are complementary technologies based on a universal interconnect, where Serial Attached SCSI customers can choose to deploy cost-effective Serial ATA in a Serial Attached SCSI environment.
