I am quite new to Netapp and it is not that easy to get to understand which goes with what.
I want to setup a lab for redundancy testing in vmware vsphere 6.x and would like to base it on some kind of SAN - also with redundancy can came accross an offer including 2 units of DS2246 with 48 disks in total.
Now what do I need to get hands on before I have a usable setup ?
Some type of FAS (or AFF), which is 2 controllers + disks / disk shelves (DSxxx). They usually ship with basic cables needed. (power and cluster networking) From what you said in your post, you will need more than just the two DS2246 shelves.
You'll also need Network xor SAN Switch(s) and ESX host(s)
What protocol are you wanting to use? you said SAN, so FC or iSCSI? or something like NFS for vmware?
When you buy a new FAS all the licensing is included. However, getting a used FAS off sites like ebay for example, you could run in to issues getting valid licenses.
Another option for you could be to use ONTAP Select which is software that can be installed on a white box or as a vm host. As long as it meets ONTAP Selects minimum requirements. This also would have a cost for just the desired licenses. This should be cheaper then Hardware and Licenses https://mysupport.netapp.com/products/p/ontap_select.html
