TrainSignal has released a course called EMC Storage Essentials which will introduce you to storage basics and the EMC VNX Series of storage. It is great to see an online training provider release courses on storage. I haven't been through the course but you can try it for yourself with a free 3 day trial. This is a great example of how to get storage and SAN knowledge without needing direct access to expensive hardware.
Here is the description from TrainSignal's Website.
This essentials course will teach you basic storage knowledge. After completing this course, students will be able to navigate the broad portfolio of EMC Midrange Products and Software Suites, better communicate and understand common storage terminology, ask the right questions when purchasing an EMC Array, understand the topology of a Storage Environment, and supplement their learning in preparation for the E10-001 EMC Proven Professional Entry Level Certification. This course is suitable for those who have little to no EMC storage knowledge, however some level of storage exposure is helpful.
