This can be misunderstood as XenServer IntelliCache (a mistake I'm sad to say I've made in the past).

With desktop virtualization, we hear more and more about how important IOPS are to being able to support the virtual desktop. I've had a few blogs about it and plan to have a few more. What I wanted to talk about was an interesting discussion I recently had with 3 Senior Architects within Citrix Consulting… Continue reading Does Cache Trump IOPS
