How to install and configure Zerto in your local environment
If you want to use UKCloud's Disaster Recovery as a Service or Migration to the Cloud services, there are some tasks that you must perform to prepare your local environment.
UKCloud's Disaster Recovery as a Service enables you to provide a secure, scalable disaster recovery solution for your on-premises environment by replicating your workloads on the UKCloud platform
Migration to the Cloud enables you to move your workloads from a local, on-premises environment onto the UKCloud platform.
Our Disaster Recovery as a Service and Migration to the Cloud services are powered by Zerto, a leading provider of disaster recovery software for the cloud, so you'll need to install Zerto software in your local environment to enable the replication of your workloads to the UKCloud platform. You'll also need to create a IPsec VPN to connect your local environment to the UKCloud platform.
To complete the steps in this guide, you must have administrator access to the vCenter Server that hosts the VMs that you want to protect or migrate.
Before you begin
When you raise a Service Request for Disaster Recovery as a Service or Migration to the Cloud, UKCloud provides you with:
A ZORG ID to identify your environment within Zerto
A link to the appropriate version of Zerto Virtual Manager (ZVM) for you to deploy in your local environment as well as a site address and port for licensing purposes
The IP address (from the IP range you provided to UKCloud) of the Zerto Cloud Connector (ZCC) deployed in your target VDC (for recovery or migration); you'll need this to complete the setup of the site-to-site VPN between your local environment and your target VDC
Access to the Zerto Self-Service Portal (ZSSP) in the UKCloud zone where your target VDC is located
Installing and configuring Zerto Virtual Manager in your local environment
As UKCloud's Disaster Recovery as a Service and Migration to the Cloud services are powered by Zerto, you need to set up Zerto Virtual Manager (ZVM) in your local environment to enable your VMs to be replicated on the UKCloud platform. ZVM is responsible for all the Zerto configuration for a site and performs the replication tasks.
UKCloud provides a version of ZVM that is compatible with the Zerto software on the UKCloud platform.
If Microsoft .NET Framework is not installed, you'll be prompted to install the required version of .NET Framework, which is included as part of the Zerto installation package. After you install .NET Framework, the machine automatically restarts and the Zerto installation begins.
Download and run the executable file from the link provided by UKCloud.
Install ZVM on a Windows Server 2012 R2, 2016 or 2019 server, ideally with nothing else running on it.
On the Welcome page of the Zerto Virtual Replication Installation for VMware vSphere wizard, read the information provided then click NEXT.
On the License Agreement page, accept the agreement and then click NEXT.
On the Select Installation Folder/Directory page, change the location if necessary and then click NEXT.
On the Choose Installation Type page, select Express installation and then click NEXT.
On the vCenter Server Connectivity page, in the IP / Host Name field, enter the address of the vCenter Server that hosts the VMs that you want to protect or migrate.
In the Username and Password fields, enter the administrator credentials for the vCenter Server.
In the Site Name field, enter a name to identify the location of this installation of ZVM and then click NEXT.
On the Validation page, fix any issues if necessary and then click RUN.
After ZVM has finished installing, on the Install Complete page, select the Open the Zerto Virtual Manager interface checkbox and then click DONE.
Log in to the Virtual Manager Web Client using your vCenter Server administrator credentials.
The first time you log in, you'll need to enter licensing details.
As you are using ZVM as part of a UKCloud service, select Pair to a site with a license and enter the Site Address and Port provided by UKCloud.
In ZVM, select the SETUP tab.
Click NEW VRA.
The Virtual Replication Appliance (VRA) manages the replication of VMs across the two sites.
In the Configure and Install VRA dialog, from the Host list, select the IP address of the server that hosts the VMs that you want to protect or migrate.
In the Host Root Password field, enter the root password of the VM host server.
Complete the other fields in the Host Details section as required.
In the VRA Network Details section, enter a static IP address and the gateway details of the network for the VRA to use.
After the VRA has finished installing, you should be able to see your new VRA in the SETUP tab.
Creating a VPN between your local environment and UKCloud
As you'll be replicating your VMs from your local environment onto the UKCloud platform, you need to create a secure connection between the two sites. You can do this by creating a site-to-site VPN.
For information about how to create a site-to-site VPN, see How to configure IPsec VPN.
The following table lists the minimum firewall rules required for Zerto to pair and replicate with the UKCloud platform.
|Source device||Target service||Port||Direction||Purpose|
|Customer ZVM||Service Provider ZCC||TCP 9081||Bi-directional||ZVM to ZCC communication|
|Customer VRA||Service Provider ZCC||TCP 4007*||Bi-directional||TCP control communication between source and target VRAs and ZCC|
|Customer VRA||Service Provider ZCC||TCP 4008*||Bi-directional||TCP communication to pass data between source and target VRAs and ZCC|
* We recommend that you use ports 9082 to 9200 to allow for increase in VRA on source and target sites.
Now that you have prepared your local environment for Disaster Recovery as a Service or Migration to the Cloud, you can create a virtual protection group (VPG) to identify the VMs that you want to protect or migrate. For more information, see How to create a virtual protection group.
