Pricing? Way too high
We get academic pricing on quite everything, also for VMWare. But still those licenses costs for VSAN are way too high, really. The idea was to use Direct Attached Storage with whatevery vendor you want, get the same features of a real SAN, but for a way lower price. (Well, it´s cheaper than HPE/3Par Storeserv appliances with its e.g. vendor locked harddrives, though)
So nowadays we have several HP EVA SANs and VMWare which need to get replaced until next year. It doesn´t matter which vendor we chose, we need training on each product except VMWare core ESXi. So, what should we get:
1. HPE Proliant DL380 server + HPE D3600/D3700 + Windows Server 2016 Datacenter + Storage Spaces
2. HPE Proliant DL380 server + HPE D3600/D3700 + VMWare + VSAN + NSX
3. HPE Proliant DL380 server + HPE/3Par/StoreServ 8000 series + VMWare + NSX
The most inexpensive option is "1", followed by "2", followed by "3"
=> VSAN sounds great, but lower the prices, please lower those prices on VSAN and for NSX, too.
