The In-Depth Serial ATA course provides students with a comprehensive insight into the
operation of the SATA interface. The class examines and explores in detail the operation of SATA at all
architectural levels. This seminar will take you on a journey starting with the basic beginnings of ATA, how
legacy parallel ATA influences the SATA architecture, and then dive deep into all technical aspects of SATA.
Discussions will include how SATA architectural advancements affect device drivers and firmware, how
Native Command Queuing differs from Tagged Command Queuing, and will cover all SATA feature sets that
need to be known in order to take full advantage of SATA technology.
This course also covers how Port Multipliers and Port Selectors are used to provide scalability and
availability to SATA designs. Other topics will include how Serial Attached SCSI and SATA are
complimentary technologies, how each architecture may influence system and server designs, and how SAS
and SATA can be used to deploy tiered storage applications.
This course is geared for any engineer or person who has to design, develop, architect, program, write
software, test, or troubleshoot SATA storage applications. This course is also accompanied by eyes-on
demonstrations using real SATA test equipment, analyzers, and disk drives. Through demonstrations of the
technology you will gain knowledge on how to design and troubleshoot every aspect of a SATA
implementation.
