Nutanix: Advanced VM Placement Intelligence: Allows your VMs to Focus on Running Workloads
Keeping data close to the compute has been one of the salient features of the Nutanix architecture and the Distributed Storage Fabric, or DSF. It provides several benefits including inherent protection against workload interference, consistent performance, and efficient utilization of high speed storage media such as SSD. As Nutanix has turned its focus towards the hypervisor, we have found opportunities to take advantage of DSF’s ability to quickly determine where any block of data resides at any given point in time. We chose to build a scheduler for AHV that has access to host telemetry and can communicate with the DSF to make placement decisions. The end result is that VMs and workloads running on AHV do not need to rely on their own resource management tools and can focus on running their workloads.
Today at the .NEXT On-Tour event in Sydney, Australia, we are happy to announce plans for an improved scheduler, the Acropolis Dynamic Scheduler. Once released, the Acropolis Dynamic Scheduler’s design will extend the traditional means of scheduling that relies upon compute utilization (CPU/MEM) to make placement decisions. The Acropolis Dynamic Scheduler leverages real-time compute and storage statistics to drive VM and volume (ABS) placement decisions.
There are two types of placement decisions:
- Initial placement – VM or workload’s initial location on a host at power-on
- Runtime Optimization – Movement of workloads based upon runtime metrics
