Hello robc,
I am guessing you already took E-Series Fundamentals.
The training actually does a really good job explaining E-Series, its technologies and its features.
Although its not a training video, you can practice with E-Series hands-on if you have access to this lab.
If you are specifically looking for more training videos, do you have a search option on the Learning Center site where you find the E-Series Fundamentals course? I think I am sent to internal site when I log into the Learning Center. I have a search bar and can find several E-Series and SANtricity related videos, but I do not think these video links will work externally. I am not sure what your view looks like or what videos you have access to so it would probably be best to see what you have access to on your version of the Learning Center.
