At VMworld, various cool new technologies were previewed. In this series of articles, I will write about some of those previewed technologies. Unfortunately, I can’t cover them all as there are simply too many. This article is about DRS 2.0, which was session HBI2880BU. For those who want to see the session, you can find it here. This session was presented by Adarsh Jagadeeshwaran and Sai Inabattini. Please note that this is a summary of a session which is discussing a Technical Preview, this feature/product may never be released, and this preview does not represent a commitment of any kind, and this feature (or it’s functionality) is subject to change. Now let’s dive into it, what is DRS 2.0 all about?
The session started with an intro, DRS was first introduced in 2006. Since then datacenters, and workloads (cloud-native architectures), have changed a lot. DRS, however, has remained largely the same over the past 10 years. What we need is a resource management engine which is more workload-centric than it is cluster-centric, that is why we are planning on introducing DRS 2.0
What has changed? In general, the changes can be placed in 3 categories:
- New cost-benefit model
- Support for new resources and devices
- Faster and scalable
