While presenting the storage performance talks, I frequently get asked about Solid State Device (SSD) performance in a virtualized environment. Well obviously, SSD’s or EFD’s (Enterprise Flash Disks) are great for performance especially if you have storage intensive workloads. As seen in the previous post in this series, SSDs can provide significantly more IOPs and significantly lower latencies. But the two big questions are ”how much of a gain might I expect” and “how much SSD storage do I need to achieve that gain” when using SSDs in a virtualized environment.
