In this article, we'll explore the differences between these two solutions – Site Recovery Manager and vSphere Replication, their deployment for disaster recovery.
- Site Recovery Manager VS vSphere Replication
- Deploy disaster recovery with Site Recovery Manager and vSphere Replication
- Reliable and easy disaster recovery solution for vSphere virtual machines
Site Recovery Manager VS vSphere Replication
Site Recovery Manager (SRM) and vSphere Replication are two VMware products designed to help organizations ensure business continuity and disaster recovery for their virtualized environments. However, vSphere replication VS Site Recovery Manager, they serve different purposes and offer distinct features.
Site Recovery Manager (SRM)
Purpose: SRM is primarily focused on automating and orchestrating the failover and failback of virtualized workloads in the event of a disaster or planned migration. It provides a comprehensive solution for disaster recovery planning and execution.
- Automated Failover and Failback: SRM automates the process of migrating virtual machines from a protected site to a recovery site in case of a disaster and facilitates the return of VMs when the disaster is over.
- Integration with Array-based Replication: SRM integrates with various storage arrays to provide array-based replication, which allows for efficient and fast data replication.
- Runbook Automation: It allows you to create and customize recovery plans to define the sequence and priority of VMs during failover.
- Testing and Non-Disruptive DR Testing: You can perform non-disruptive DR testing to ensure your DR plans work as expected without impacting production.
Purpose: vSphere Replication is focused specifically on replicating virtual machine data from one ESXi host or vCenter Server to another within or between data centers. It's more focused on providing data replication capabilities.
- VM-Level Replication: vSphere Replication replicates individual virtual machines at the virtual disk level.
- Hypervisor-Based Replication: It operates independently of storage arrays, making it storage-agnostic and suitable for a wider range of storage solutions.
- Lower Cost: vSphere Replication is included with certain vSphere editions, making it a cost-effective choice.
Therefore, the choice between SRM and vSphere Replication depends on your organization's specific needs and budget. Many organizations also use both products in combination to achieve a balance between comprehensive DR capabilities and cost efficiency.
Deploy disaster recovery with Site Recovery Manager and vSphere Replication
Deploying disaster recovery with SRM and vSphere Replication involves several steps to ensure that your virtualized environment is well-protected and can quickly recover from unexpected incidents. Below, I'll outline the key steps to deploy disaster recovery with SRM and vSphere Replication:
✤ Install SRM in Azure VMware Solution
1. Install VMware Site Recovery Manager and vSphere Replication within your on-premises data center.
2. Within your Azure VMware Solution private cloud, navigate to the Manage section and then choose Add-ons >> Disaster recovery.
3. The default CloudAdmin user in your Azure VMware Solution private cloud lacks the necessary privileges to execute the installation of VMware SRM or vSphere Replication. The installation procedure involves several steps detailed in the “Prerequisites” section. Alternatively, you have the option to install VMware SRM along with vSphere Replication as an additional service directly from your Azure VMware Solution private cloud.
4. Within the Disaster Recovery Solution menu, select VMware Site Recovery Manager (SRM) – vSphere Replication.
5. Input your License key, agree to the terms and conditions, and proceed by selecting the Install option.
✤ Install and configure vSphere Replication appliance
1. On the Disaster recovery tab, pick vSphere Replication from the Replication using drop-down menu.
2. Adjust the vSphere server slider to specify the quantity of replication servers required, corresponding to the number of VMs you intend to protect. Afterward, click on the Install button.
3. After installation, confirm the presence of both VMware SRM and the vSphere Replication appliances.
✤ Configure site pairing in vCenter Server
After installing VMware SRM and vSphere Replication, you need to complete the configuration and site pairing in vCenter Server.
1. Sign into the vSphere Client as [email protected].
2. Proceed to the Site Recovery section, inspect the status of both vSphere Replication and VMware SRM, and then click on OPEN Site Recovery to initiate the client.
3. In the new tab that opens within the Site Recovery (SR) client, opt for NEW SITE PAIR.
4. Input the requisite information for the remote site, and then click NEXT.
5. Click CONNECT to approve the certificate for the remote vCenter Server. At this juncture, the client should automatically identify the VMware VRM and VMware SRM appliances on both ends as services eligible for pairing.
6. Choose the appliances you wish to pair and then proceed by clicking NEXT.
7. Click CONNECT to approve the certificates for both the remote VMware SRM and the remote vCenter Server once more. Likewise, click CONNECT to accept the certificates for the local VMware SRM and the local vCenter Server.
8. Review the configured settings and subsequently click FINISH. If the operation succeeds, the client will present an additional panel for the pairing process. However, if it encounters any issues, an alarm will be generated and reported.
9. In the lower-right corner, select the upward-pointing double arrow to expand the panel, revealing Recent Tasks and Alarms.
10. Select VIEW DETAILS to access the panel for remote site pairing. This action will open a dialogue prompting you to sign in to the remote vCenter Server.
11. Provide the username with the necessary permissions for replication and site recovery, and then click LOG IN.
This login, which may be different from the previous one, is a one-time requirement to establish the pairing. The SR client will request this login each time it is launched for working with the pairing.
