In my time with ESG Lab, I have seen and tested numerous virtual desktop solutions and reference architectures. It’s common knowledge that virtualizing end-user computing environments can present the most challenging workloads an infrastructure must support. Users have become accustomed to the performance of flash drives in their business and personal computers, making delivery of an exceptional user experience–essential to the success of desktop virtualization–even more challenging. If you can’t deliver performance equal to or better than what users already have, you’ve already lost.
