DRS 2.0: The Future of Virtual Machine Management
VMworld 2016 was a platform for VMware to showcase its latest and greatest technologies, and one of the most exciting announcements was the preview of DRS 2.0 (#HBI2880BY). As a follow-up to my previous article on the cool new technologies previewed at VMworld, I’m going to dive deeper into what DRS 2.0 has in store for us.
For those who may not be familiar, DRS (Distributed Resource Scheduler) is a core feature of vSphere that enables administrators to manage virtual machine (VM) resources and ensure that they have the necessary resources to run smoothly. DRS 2.0 is a significant upgrade to the current version, offering several new features and improvements that will revolutionize the way we manage VMs.
One of the most anticipated features of DRS 2.0 is the ability to perform resource pooling across clusters. This means that administrators can now pool resources from multiple clusters and allocate them more efficiently. This feature will be especially useful for large-scale virtualized environments, where resources need to be allocated across multiple clusters.
Another significant improvement in DRS 2.0 is the new algorithm used for resource allocation. The current version of DRS uses a simple algorithm that allocates resources based on the number of VMs running on a host. However, this can lead to suboptimal resource utilization, especially in environments with varying workloads. The new algorithm used in DRS 2.0 takes into account factors such as workload priority, resource usage patterns, and host capabilities to provide more accurate and efficient resource allocation.
DRS 2.0 also introduces a new feature called “Resource Containers”. Resource Containers allow administrators to create isolated resource pools for specific workloads or business units. This feature is particularly useful in environments where different teams or departments have varying resource requirements. With Resource Containers, administrators can ensure that each team has access to the resources they need without impacting other teams.
In addition to these new features, DRS 2.0 also includes several performance and scalability improvements. For example, the new version uses a more efficient algorithm for calculating resource usage, which results in faster and more accurate resource allocation. Additionally, DRS 2.0 has been optimized for larger environments, allowing it to handle more hosts and VMs than ever before.
Overall, DRS 2.0 is a significant upgrade to the current version, offering several new features and improvements that will revolutionize the way we manage virtual machines. With its ability to pool resources across clusters, use a more sophisticated resource allocation algorithm, and provide isolated resource pools for specific workloads, DRS 2.0 is set to become an essential tool for any vSphere administrator. If you’re looking to stay ahead of the curve and optimize your virtualized environment, be sure to check out DRS 2.0 when it becomes available.
