Operations Manager VMware vSphere: Install, Configure, Manage © 2015 VMware Inc All rights reserved 8-4 Lesson 1: Virtual CPU and Memory Concepts 8-5 © 2015 VMware Inc All rights reserved Learner Objectives By the end of this lesson, you should be able to meet the following objectives: • Discuss CPU and memory concepts in a virtualized environment • Describe what overcommitment of a resource means • Identify additional technologies that improve memory utilization • Describe how VMware vSphere® Virtual Symmetric Multiprocessing works and how hyperthreading is used by the VMkernel VMware vSphere: Install, Configure, Manage © 2015 VMware Inc All rights reserved 8-6 Memory Virtualization Basics VMware vSpheređ has three layers of memory: ã Guest operating system virtual memory is presented to applications by the operating system • Guest operating system physical memory is presented to the virtual machine by the VMkernel • Host machine memory that is managed by the VMkernel provides a contiguous, addressable memory space that is used by the virtual machine Virtual Machine Application Operating System Guest OS Virtual Memory Guest OS Physical Memory ESXi Host ESXi Host Machine Memory VMware vSphere: Install, Configure, Manage © 2015 VMware Inc All rights reserved 8-7 Virtual Machine Memory Overcommitment Memory is overcommitted when the combined Host machine memory = GB working memory footprint of all virtual machines exceeds that of the host memory sizes Total configured VM memory = GB Virtual machines not always use their full allocated memory On Off On On An ESXi host transfers memory from idle virtual machines to virtual machines that need more 1GB memory to improve memory utilization 1GB 1GB 1GB Memory overhead is stored in a swap file (.vswp) vmxd-*.vswp VM VM VM vswp vswp vswp VMware vSphere: Install, Configure, Manage © 2015 VMware Inc All rights reserved 8-8 Memory Reclamation Techniques Economize use of physical memory pages: • Transparent page sharing allows pages with identical contents to be stored only once Deallocate memory from one virtual machine for another: • Ballooning mechanism, active when memory is scarce, forces virtual machines to use their own paging areas Memory compression: • Attempts to reclaim some memory performance when memory contention is high Host-level SSD swapping: • Use of a solid-state drive (SSD) on the host for a host cache swap file might increase performance Page virtual machine memory out to disk: • Use of VMkernel swap space is the last resort due to the poor performance

reserved 8-86 Finishing the Installation To finish the installation, log in to any cluster data node (master node, master replica node, or data node) as user admin Complete a one-time process to license the product or use the product evaluation mode VMware vSphere: Install, Configure, Manage © 2015 VMware Inc All rights reserved 8-87 Configuring Solutions for Objects To continue with the final steps of your new installation, you add solutions for the kinds of objects that you want to monitor and manage VMware vSphere: Install, Configure, Manage © 2015 VMware Inc All rights reserved 8-88 About the User Interface vRealize Operations Manager has the following user interfaces: • Administration interface: – Used to perform initial setup and installation – Used to perform software updates – Used only by the vRealize Operations Manager administrator – Accessed through the URL https://vRealize_Operations_Manager_name/admin • Product user interface: – Used to perform the following tasks: • Monitor the environment for health, risk, and efficiency issues • Add custom content, such as views, dashboards, and reports • Administer the vRealize Operations Manager instance – Used by all vRealize Operations Manager users – Accessed through the URL https://vRealize_Operations_Manager_name/vcops-web-ent VMware vSphere: Install, Configure, Manage © 2015 VMware Inc All rights reserved 8-89 Major and Minor Badges With the badge identifier system, you can quickly identify good or bad conditions in your vSphere virtual infrastructure:  Major badges: • Health • Risk • Efficiency  Minor badges: • Workload • Anomalies ã Faults VMware vSphere: Install, Configure, Manage â 2015 VMware Inc All rights reserved 8-90 About the Home Page The home page appears when you log in The home page provides access to all of your dashboards The dashboard provides a quick overview of the performance and condition of your virtual infrastructure VMware vSphere: Install, Configure, Manage © 2015 VMware Inc All rights reserved 8-91 Widgets on the Recommendations Dashboard A widget is a pane on a dashboard that can visualize the behavior of one or more objects The Recommendations dashboard uses the Health, Risk, Efficiency, and the Top Alerts widgets VMware vSphere: Install, Configure, Manage © 2015 VMware Inc All rights reserved 8-92 vSphere Dashboards Prebuilt vSphere dashboards assist in monitoring resource usage and performance of vSphere clusters, hosts, datastores, and virtual machines VMware vSphere: Install, Configure, Manage © 2015 VMware Inc All rights reserved 8-93 About Inventory Trees An inventory tree shows the parent-child relationships between objects: • Object relationships are useful when troubleshooting system issues and finding the cause Inventory trees and tree types are provided by management packs (solutions) when they are installed into vRealize Operations Manager: • For example, the VMware vSphere solution provides several inventory tree types related to vSphere Tree Types VMware vSphere: Install, Configure, Manage © 2015 VMware Inc All rights reserved 8-94 Selecting an Inventory Tree Type Selecting an inventory tree type enables you to see the objects in the inventory tree instances Tree The root of vSphere inventory trees is the vSphere Type World object vSphere World consists of all vCenter Server instances Tree Instance and their objects Objects Tree Instance VMware vSphere: Install, Configure, Manage © 2015 VMware Inc All rights reserved 8-95 Viewing an Object’s Details When you select an object in the navigation pane, the object’s details appear in the center pane VMware vSphere: Install, Configure, Manage © 2015 VMware Inc All rights reserved 8-96 About the Administration Page The Administration page enables you to configure various aspects of vRealize Operations Manager VMware vSphere: Install, Configure, Manage © 2015 VMware Inc All rights reserved 8-97 Lab 20: (Optional) Using vRealize Operations Manager

VMware vSphere: Install, Configure, Manage © 2015 VMware Inc All rights reserved 8-98 Review of Learner Objectives You should be able to meet the following objectives: • Identify the VMware vRealize™ Operations Manager™ architecture • Explain how to deploy and configure a vRealize Operations Manager appliance • Use alerts and badges to monitor the vSphere environment VMware vSphere: Install, Configure, Manage © 2015 VMware Inc All rights reserved 8-99 Key Points • For proper resource management, vSphere has mechanisms to enable less, more, or an equal amount of access to a defined resource • vSphere prevents a virtual machine from consuming large amounts of a resource and grants a guaranteed amount of a resource to a virtual machine whose performance is not adequate or requires a certain amount of a resource to run properly • • • • A resource pool enables you to divide and allocate resources to virtual machines and other resource pools The Performance tab enables you to monitor the performance of a host or a virtual machine in real time or over a period of time You use alarms to monitor the vCenter Server inventory and send out notifications when selected events or conditions occur vRealize Operations Manager gives you insight into the performance, capacity, and health of the vSphere environment Questions?
