VMware vSphere 7 DRS scalable shares dynamically calculates the CPU entitlements for all workloads in a resource pool The resource pool with the CPU shares set to high means the CPU entitlement calculated is more than the resource pool shares set to normal which makes much more sense. You can see how this works here.Īs you can see below, the same scenario as shown above yields different results.
In an example that is given by VMware, explaining how this new mechanism works, it was explained that with the traditional vSphere DRS, the CPU share level did not necessarily guarantee a higher entitlement. In VMware vSphere releases before vSphere 7, there was no relative resource entitlement between resource pools and the workloads that were assigned to them. This is what they have done with the VMware vSphere 7 DRS functionality. It is almost as if they went back to the drawing board on the core features and took at look at how they could redesign and make things more powerful, more efficient, and better overall. What are VMware vSphere 7 Scalable Shares? What problem does it solve? VMware took a hard look at many of the core features of VMware vSphere with the vSphere 7 release. What is VMware vSphere 7 scalable shares? How does it work? Let’s take a look. The new scalable shares in the VMware vSphere 7 DRS component is a refinement of how VMware implements resource scheduling in vSphere 7. One of these really powerful improvements that has been made is something VMware calls Scalable Shares. VMware has made a lot of new improvements with the Distributed Resource Scheduler (DRS) in VMware vSphere 7.
