DESIGNING GIGABIT INTERFACES |
This seminar is designed for those wanting to venture into the electrodynamic and mechanical features of this course. As a stand-alone complement to "Storage Networking Lab," this seminar is designed to educate hardware engineers and field personnel on how to properly design, test, and connect SAN devices and components to produce a working and reliable SAN. In this seminar you will gain a clear understanding of the electrical and optical operation for the many different SAN serial and serial-parallel link variants and the underlying technology that provides the basis for all SANs regardless of protocol. Line drivers and receivers will be explored. How to evaluate signal quality, recognize potentially harmful performance, design for specific objectives and how to correct inadequate designs will also be covered. We will also discuss methods for field diagnosis of common problems.
