What is VMware Site Recovery Manager (SRM)?

Before we jump into the specifics of version 8.x, let’s cover the basics. VMware SRM is a business continuity and disaster recovery solution that helps you plan, test, and automate the recovery of virtual machines in case of a disaster. It works by replicating your virtual machines from a protected site to a recovery site, and then orchestrating the failover process when needed. SRM integrates tightly with VMware vSphere, making it a natural extension of your virtualized environment. This integration simplifies the setup and management of your disaster recovery plans. Essentially, SRM takes the headache out of disaster recovery by automating what would otherwise be a complex and manual process. Imagine having to manually recover hundreds of virtual machines after a disaster – not fun, right? SRM eliminates that pain, allowing you to recover your systems quickly and efficiently.

SRM achieves this through the use of recovery plans. A recovery plan defines the steps required to recover a set of virtual machines, including the order in which they should be started, the network configuration, and any custom scripts that need to be executed. These plans can be customized to meet the specific needs of your applications and business requirements. For example, you might have different recovery plans for different departments or applications, each with its own unique recovery objectives. SRM also provides features for testing your recovery plans without actually disrupting your production environment. This allows you to validate your disaster recovery strategy and ensure that it works as expected when a real disaster occurs. Regular testing is crucial for maintaining confidence in your disaster recovery plan and identifying any potential issues before they become problems. Moreover, SRM provides detailed reporting and monitoring capabilities, giving you visibility into the status of your protected virtual machines and the progress of recovery operations. This allows you to track your recovery time objectives (RTOs) and recovery point objectives (RPOs) and ensure that you are meeting your business requirements.

Understanding the Architecture

To truly grasp how VMware SRM works, let's break down its architecture. At its core, SRM involves two sites: the protected site and the recovery site. The protected site is where your production virtual machines reside, while the recovery site is where your replicated virtual machines are stored. SRM uses a central server to manage the replication and recovery processes. This server communicates with vCenter Server at both the protected and recovery sites, as well as with the replication appliances or storage arrays.

The key components of the SRM architecture include:

• SRM Server: This is the central management component of SRM. It is responsible for managing replication, creating and executing recovery plans, and monitoring the status of protected virtual machines.
• vCenter Server: SRM integrates with vCenter Server to manage virtual machines and infrastructure resources. vCenter Server provides the inventory and configuration information that SRM needs to orchestrate the recovery process.
• Replication Appliance or Storage Array: SRM supports both vSphere Replication and array-based replication. vSphere Replication uses a software-based replication appliance to replicate virtual machines, while array-based replication leverages the replication capabilities of your storage arrays.
• Site Recovery Manager Database: SRM uses a database to store configuration information, recovery plans, and historical data. This database is essential for the proper functioning of SRM.

The communication between these components is crucial for the successful operation of SRM. The SRM server communicates with vCenter Server to discover virtual machines and infrastructure resources. It also communicates with the replication appliance or storage array to initiate and monitor replication. When a disaster occurs, the SRM server uses the recovery plans to orchestrate the failover process, bringing the replicated virtual machines online at the recovery site.

Installation and Configuration

Setting up VMware SRM 8.x involves a few key steps. First, you need to ensure that you have a compatible version of vCenter Server installed at both the protected and recovery sites. Next, you'll need to deploy the SRM appliance at each site. The SRM appliance is a pre-packaged virtual machine that contains the SRM server and all its dependencies. Once the appliances are deployed, you'll need to configure them and connect them to the respective vCenter Servers.

The configuration process involves specifying the vCenter Server connection settings, configuring the replication settings, and creating recovery plans. You'll also need to configure the network mappings to ensure that the virtual machines at the recovery site can communicate with the rest of your network. It's essential to carefully plan your network configuration to avoid any connectivity issues during a failover. One of the critical aspects of the configuration is setting up the replication. You can choose between vSphere Replication and array-based replication, depending on your requirements and infrastructure. vSphere Replication is a software-based replication solution that is easy to set up and manage, while array-based replication leverages the replication capabilities of your storage arrays for better performance. After configuring the replication, you can create recovery plans that define the steps required to recover your virtual machines. These plans can be customized to meet the specific needs of your applications and business requirements. It’s important to test these plans regularly to ensure they work as expected. Testing is a crucial part of the disaster recovery process, as it helps you identify and address any potential issues before they become problems. SRM allows you to perform non-disruptive testing, which means you can test your recovery plans without impacting your production environment. This allows you to validate your disaster recovery strategy and ensure that it is effective. By following these steps carefully, you can set up VMware SRM 8.x and protect your virtualized environment from disasters.

Creating and Managing Recovery Plans

The heart of VMware SRM lies in its recovery plans. These plans define the steps needed to recover your virtual machines in a specific order, ensuring that applications come online correctly. When creating a recovery plan, you specify the virtual machines to include, the order in which they should be started, and any dependencies between them. For example, you might want to start your database servers before your application servers to ensure that the applications have access to the necessary data. You can also configure custom scripts to be executed during the recovery process. This allows you to automate tasks such as updating DNS records or reconfiguring network settings. Recovery plans can be customized to meet the specific needs of your applications and business requirements. For example, you might have different recovery plans for different departments or applications, each with its own unique recovery objectives. When managing recovery plans, it’s essential to keep them up-to-date. This means regularly reviewing and updating the plans to reflect any changes in your environment. For example, if you add new virtual machines or change the configuration of existing ones, you’ll need to update your recovery plans accordingly. It’s also important to test your recovery plans regularly to ensure that they work as expected. Testing helps you identify any potential issues and address them before a real disaster occurs. SRM allows you to perform non-disruptive testing, which means you can test your recovery plans without impacting your production environment. This allows you to validate your disaster recovery strategy and ensure that it is effective. By creating and managing recovery plans effectively, you can ensure that your virtual machines are recovered quickly and efficiently in the event of a disaster.

Testing and Failover Procedures

One of the most crucial aspects of using VMware SRM is testing your recovery plans. Regular testing ensures that your disaster recovery strategy is effective and that you can recover your systems quickly and efficiently when a real disaster occurs. SRM provides a non-disruptive testing feature that allows you to test your recovery plans without impacting your production environment. This is essential for validating your disaster recovery strategy and identifying any potential issues before they become problems. The testing process involves creating a temporary snapshot of your virtual machines at the protected site and then recovering them at the recovery site. This allows you to verify that the virtual machines come online correctly and that all the necessary applications and services are functioning as expected. During the testing process, SRM provides detailed reporting and monitoring capabilities, giving you visibility into the status of your virtual machines and the progress of the recovery operations. This allows you to track your recovery time objectives (RTOs) and recovery point objectives (RPOs) and ensure that you are meeting your business requirements. If you encounter any issues during testing, you can update your recovery plans and retest them until you are confident that they work as expected. When a real disaster occurs, the failover process is similar to the testing process. The main difference is that the failover is a permanent operation, while the testing is temporary. During a failover, SRM shuts down the virtual machines at the protected site and brings them online at the recovery site. This ensures that your applications and data are protected and that your business can continue to operate even in the face of a disaster. The failover process is fully automated, which reduces the risk of human error and speeds up the recovery process. SRM also provides features for failing back to the protected site after the disaster has been resolved. This allows you to restore your systems to their original location and resume normal operations. By regularly testing your recovery plans and following the proper failover procedures, you can ensure that your business is protected from the impact of disasters.
