I saw this link on a HN post about using Optane with memcached today. Packet.net is a bare-metal cloud provider that I have tested things on in the past with great success.
They are doing some co-promotion thing with Intel and giving away time on machines with Optane SSDs installed for open source projects. The class of machine they are installed on most likely also have 10GbE or faster, so I think it would be a good benchmarking environment.
If someone is interested in benchmarking FoundationDB with Optane, this would be a great opportunity to do it without actually having to buy the extremely expensive devices!
