@Oksana said in VMware DRS: Smarter Resource Management for vSphere:

Managing VMware clusters by hand can quickly become overwhelming as workloads grow and shift. That’s where Distributed Resource Scheduler (DRS) steps in – keeping clusters stable, apps fast, and admins stress-free.
In our latest guide by Dmytro Malynka for StarWind, we break down everything you need to know about VMware DRS: how it works, its requirements, key features, and why it’s a must-have for medium and large clusters. Read more here: https://starwind.com/s/wg
DRS sounds like a great thing on the surface before actually implementing it. In large clusters, VMs with heavy workloads get moved between hosts often with the associated disruptions when memory gets locked. Takes what is already a poor situation and makes it worse!
I formerly worked at an employer that had a very large VMWare cluster implemented with vSphere, vCloud and DRS enabled. They were up to 50 hosts when I left, and constantly ran into issues because of DRS.
