Aren't those netapp shelves pretty old at this point? See a lot of people recommending against them even for homelab type uses. You can get those 60 drive SuperMicro JBODs for pretty cheap now, and those aren't too old, would have been my choice.
Plus, the TCO is already way under the cloud equiv. so might as well spend a little more to get something much newer and more reliable
yeah it's on the wishlist to try
Thanks to op for actually replying to the various comments here - really appreciate that (and for the initial of course!)
