Evorail vs flexpod
From what I've been told, one has the software installed, the other just has the software stack tested against it. evo is also smaller than flexpod so will suit normal environments with just a few servers. I wasn't aware of an SDS requirement for Evo so this isn't such a surprise and I think its a great solution to have full private cloud easily deployable but with proper storage and a full feature set which is currently unmatched by the SDS vendors, along with the performance and reliability which they also find hard to match outside of the marketing slides...
