Make VMware vCenter Server™ and the components that it relies on highly available vCenter Server relies on these major components: • vCenter Server database: – • Create a cluster for the database Authentication identity source: – For example, VMware Center™ Single Sign-On™ and Active Directory – Set up with multiple redundant servers Methods for making vCenter Server available: • Use vSphere HA to protect the vCenter Server virtual machine VMware vSphere: Install, Configure, Manage © 2015 VMware Inc All rights reserved 9-8 About vSphere HA vSphere HA uses multiple ESXi hosts configured as a cluster to provide rapid recovery from outages and cost-effective high availability for applications running in virtual machines Protects against Protects against datastore server failures accessibility failures Protects against application failures Protects virtual machines against network isolation VMware vSphere: Install, Configure, Manage © 2015 VMware Inc All rights reserved 9-9

Tolerance on a Virtual Machine You can turn on vSphere Fault Tolerance for a virtual machine through the VMware vSpheređ Web Client VMware vSphere: Install, Configure, Manage â 2015 VMware Inc All rights reserved 9-60 Review of Learner Objectives You should be able to meet the following objectives: • List VMware vSpheređ Fault Tolerance requirements and limitations ã Describe vSphere Fault Tolerance operation VMware vSphere: Install, Configure, Manage © 2015 VMware Inc All rights reserved 9-61 Lesson 5: vSphere Replication and vSphere Data Protection 9-62 © 2015 VMware Inc All rights reserved Learner Objectives By the end of this lesson, you should be able to meet the following objectives: ã Describe VMware vSpheređ Replication ã Identify vSpheređ Data Protection™ requirements • List vSphere Data Protection sizing guidelines • Describe vSphere Data Protection installation and configuration • Explain how to back up and restore data with vSphere Data Protection VMware vSphere: Install, Configure, Manage © 2015 VMware Inc All rights reserved 9-63 About vSphere Replication vSphere Replication is an extension to vCenter Server It provides hypervisor-based virtual machine replication and recovery vSphere Replication Source vSphere vSphere vSphere vSphere Target VMware vSphere: Install, Configure, Manage © 2015 VMware Inc All rights reserved 9-64 vSphere Replication Appliance The vSphere Replication appliance provides all the components required to perform vSphere replication vSphere Replication Appliance VMware vSphere: Install, Configure, Manage © 2015 VMware Inc All rights reserved 9-65 How Replication Works vSphere Replication enables replication of a virtual machine from a source site to a target site, monitoring and managing the status of the replication, and recovering the virtual machine at the target site Replication Between Two Sites VMware vSphere: Install, Configure, Manage © 2015 VMware Inc All rights reserved 9-66 Steps for Full Recovery vSphere Replication integrates with Volume Shadow Copy Service through VMware Tools Validates Validates your your choices choices as as you you go go VMware vSphere: Install, Configure, Manage © 2015 VMware Inc All rights reserved 9-67 About vSphere Data Protection vSphere Data Protection is a robust, easily deployed, disk-based backup and recovery solution vSphere Data Protection VMware vSphere: Install, Configure, Manage © 2015 VMware Inc All rights reserved 9-68 vSphere Data Protection Requirements and Architecture vSphere Data Protection requires vCenter Server, either the Windows implementation or vCenter Server™ Appliance™ vSphere Data Protection Components VMware vSphere: Install, Configure, Manage © 2015 VMware Inc All rights reserved 9-69 vSphere Data Protection Deployment and Configuration vSphere Data Protection is deployed using vSphere Web Client from a prepackaged Open Virtualization Archive (OVA) file vSphere Data Protection: Configuring the UI to Run in Maintenance Mode VMware vSphere: Install, Configure, Manage © 2015 VMware Inc All rights reserved 9-70 Creating and Editing a vSphere Data Protection Backup Job You create and edit a backup job on the Backup tab of the vSphere Data Protection UI in the vSphere Web Client Creating a Custom Retention Policy VMware vSphere: Install, Configure, Manage © 2015 VMware Inc All rights reserved 9-71 Performing Restores with vSphere Data Protection You can restore an entire virtual machine from the Restore tab in the vSphere Data Protection UI: • The administrator can browse the list of protected virtual machines and select one or more restore points • Individual VMDKs can also be restored VMware vSphere: Install, Configure, Manage © 2015 VMware Inc All rights reserved 9-72 Review of Learner Objectives You should be able to meet the following objectives: • Describe VMware vSpheređ Replication ã Identify vSpheređ Data Protection requirements ã List vSphere Data Protection sizing guidelines • Describe vSphere Data Protection installation and configuration • Explain how to back up and restore data with vSphere Data Protection VMware vSphere: Install, Configure, Manage © 2015 VMware Inc All rights reserved 9-73 Key Points • • • • • • vSphere HA restarts virtual machines on the remaining hosts in the cluster • vSphere Data Protection is a backup and recovery solution from VMware Hosts in vSphere HA clusters have a master-slave relationship You implement redundant heartbeat networks either with NIC teaming or by creating additional heartbeat networks vSphere Fault Tolerance provides zero downtime for applications that must be available at all times vSphere Replication can be used to protect virtual machines as part of a disaster recovery strategy vSphere Replication is the only hypervisor-based replication solution that operates at the individual VMDK level, enabling replication between datastores hosted on any storage Questions?
