Serial Attached SCSI-2 (SAS-2) Update Course  
 

Sometimes it can be difficult to stay on top of the changes that occur when a new standard is released by the T10 standards committee. When the SAS-2 standard was approved last year (January 2009), it included fundamental changes to not only the architecture but also included extensive additions to the management protocol and physical interface.

This course was developed to complement the “In-Depth Exploration of Serial Attached SCSI” training that you may have attended prior to the new SAS-2 standard. While we have made incremental updates to our documentation to keep it current, we felt it was important to develop a short course that just covers the fundamental differences between SAS-1 and SAS-2.

In this course you will learn about the changes to SAS terminology, architectural additions including zoning, the new SMP functions, changes to the SCSI Mode Pages that pertain to SAS, changes to speed negotiation, and the changes to the physical interface. You will also learn about the next phase of the SAS standards including the pending release of the SAS Protocol Layer (SPL) document and the SAS 2.1 standard which details new optical media options.

Who Should Attend: This in-depth technical class is targeted towards hardware and software engineers involved in the design, development, integration, deployment, test, and maintenance of Serial Attached SCSI storage devices, storage subsystems and servers that intend to utilize SAS technology.
Prerequisites: The attendee should have attended the “In-depth Exploration of SAS” training or have equivalent experience. Prior detailed knowledge of the SAS architecture is required to fully understand SAS-2 updates. This course does not replace our standard SAS training. If you attend this class without prior SAS knowledge or experience, you will not be able to comprehend the material.
Course Length:

1 day in a face-to-face training or two half-day virtual class sessions
