System Center 2016 Virtual Machine Manager Cookbook - Third Edition

By: Roman Levchenko, EDVALDO ALESSANDRO CARDOSO

Overview of this book

Virtual Machine Manager (VMM) 2016 is part of the System Center suite to configure and manage datacenters and offers a unified management experience on-premises and Azure cloud. This book will be your best companion for day-to-day virtualization needs within your organization, as it takes you through a series of recipes to simplify and plan a highly scalable and available virtual infrastructure. You will learn the deployment tips, techniques, and solutions designed to show users how to improve VMM 2016 in a real-world scenario. The chapters are divided in a way that will allow you to implement the VMM 2016 and additional solutions required to effectively manage and monitor your fabrics and clouds. We will cover the most important new features in VMM 2016 across networking, storage, and compute, including brand new Guarded Fabric, Shielded VMs and Storage Spaces Direct. The recipes in the book provide step-by-step instructions giving you the simplest way to dive into VMM fabric concepts, private cloud, and integration with external solutions such as VMware, Operations Manager, and the Windows Azure Pack. By the end of this book, you will be armed with the knowledge you require to start designing and implementing virtual infrastructures in VMM 2016.

Configuring Dynamic Optimization and Power Optimization


Dynamic Optimization (DO) is a VMM feature that initiates live migration of VMs that are on a cluster, to improve load balancing among cluster nodes and to correct any placement constraint violations.

Note

VM Load Balancer (Node Fairness), available in Windows Server 2016, will be turned off if dynamic optimization is enabled in VMM fabric.

It can be configured with a specific frequency and aggressiveness on a host group, which determines the amount of load discrepancy required to trigger a live migration through DO.

DO settings can be configured for the CPU, memory, disk I/O, and network I/O.

By default, VMs are migrated every 10 minutes with medium aggressiveness. You must take into consideration the resource cost (for example, the network) of extra migrations against the advantages of load balancing among cluster nodes, when setting the frequency and aggressiveness for DO.

Note

By default, a host group inherits DO settings from its parent...
