If you attended VMworld 2009 and listened to Steve Herrod's key note you would have heard him discussing how to make an ESX cluster (he refered to it as a giant computer) as efficient as possible. The key element to achieve this is Distributed Resource Scheduler (DRS). DRS uses on one of the most powerful features of ESX - VMotion for balancing workloads across datacenters. Steve called DRS a 'MATCHMAKER' - matching resource requirements of virtual machines with available hardware resources.
If you are interested in knowing more about the experiments and performance results refer to my blog article on VMware VROOM: Application Performance Improvement with DRS
This is my personal blog. Here I will talk about my current work, future plans, interesting problems I faced in my day-to-day work and possibly solutions to those problems, things I don't talk in my papers and blogs.
