I found Neil Anderson on Twitter @flackboxtv. Neil is a CCIE as well as NetApp, VMware, FlexPod, Microsoft and AWS certified. His blog, Flackbox, is about Cloud and Data Center technologies. Neil has many great video tutorials on NetApp and, more broadly, on SAN and NAS Storage Basics.
Neil is also offering a free 177 page eBook "How to Build A NetApp ONTAP 9 Lab". The lab is built on VMware Player with VyOS routing between networks. The lab includes two NetApp ONTAP clusters, SnapMirror, SnapVault, Windows and Linux hosts. To minimize host memory usage, not every VM needs to be powered on at the same time.
Flackbox is definitely worth checking out.
