We were fortunate enough to get a 30 day hardware trial before we decided to buy the Solidfire solution (this was just prior to NetApp's acquisition). Our main motivation for going to Solidfire at the time was driven by the attraction of QoS at the volume level. Our FAS array was always bottlenecked at the CPU as we added more and more drives. As a result we suffered heavily to "noisy neighbor" issues at the VM level no matter how much we tuned our VM environment. During our testing of the Solidfire array we simulated much of our production environment, being that we are primarily education, we ran several SCCM imaging cycles to test labs. When we got our results, we were stunned by how well the QoS worked. Eventually, we performed the same tests over and over, but this time we manually failed over node units, pulling drives out, ect. until we reached the arrays break point. It's incredibly resilient and simple to use. It took less than 45min (with zero training on the OS) to serve data once the nodes were booted up. It took longer to rack them up. It's a fantastic system!
