Thinner and more flexible cabling for improved enclosure airflow and ease of installation e Scalability to higher performance levels In addition Serial ATA makes the transition from parallel ATA easy by providing legacy software support Serial ATA was designed to allow you to install a Serial ATA host adapter and Serial ATA disk drive in your current system and expect all of your existing applications to work as normal The Serial ATA interface connects each disk drive in a point to point configuration with the Serial ATA host adapter There is no master slave relationship with Serial ATA devices like there is with parallel ATA If two drives are attached on one Serial ATA host adapter the host operating system views the two devices as if they were both masters on two separate ports This essentially means both drives behave as if they are Device O master devices The host adapter may optionally emulate a master slave environment to host software where two devices on separate Serial ATA ports are represented to host software as a Device O master and Device 1 slave accessed at the same set of host bus addresses A host adapter that emulates a master slave environment manages two sets of shadow registers This is not a typical Serial ATA environment Barracuda SATA Product Manual Rev B 9 Introduction www seagate com The Serial ATA host adapter and drive share the function of emulating parallel ATA device behavior to pro
