I will have reason to start buying rack-based servers for a large project within the next quarter and I can see directing those server purchases to Optane-equipped SuperMicros like https://www.storagereview.com/review/supermicro-superserver-with-intel-optane-dc-persistent-memory-first-look-review, although I'll almost certainly go for a higher-end unit than the one in this quoted review. We can use a couple of them as validation mules. -- Don Wilde **************************************************** * What is the Internet of Things but a system * * of systems including humans? * ****************************************************
