Zerto Replication

One of the most exciting products I have worked with for DR has been Zerto.  I had never heard about it before working at my current job, but was put on a project to finish a Zerto install/configuration.  Zerto does full time replication to remote sites for DR.  It is fully automated and GUI driven, and whats most important, easy to set up and monitor.


Setup is simple and intuitive.  After installing the software on our server, you are asked to input the license key, or join to a license server.  After that, you are brought to the main dashboard where you will begin to deploy the VRAs.  These are small VMs that run on each host that handle the replication.  Zerto pairs with your vCenter server during the install, so it will list all of your hosts in the setup window.


Once you select “New VRA” you will be given a wizard to fill out the information for the VRA.


Once you have installed the VRAs on all of the hosts, its time to pair with another site.  Choose Sites from the ribbon, then select Pair.  Its as easy as inputting the IP address of the other Zerto site and clicking Pair.


Now that we have a our Zerto sites paired, the next step is to create a VPG (Virtual Protection Group) which is a group of VMs that is replicated based on an SLA that you set.  You select VPGs from the ribbon and it will bring you to the following screen.


Select “New VPG” and follow the wizard. First, the VPG needs to be named and given a priority.  Priority would order your different VPGs and queue them in the the priority order when network resources are scarce.


Then select the VMs that you want included in the VPG.


Select the site you want it replicated to.


Select the storage requirements for the VM at the DR site.


Configure recovery network settings (if different than your defaults) and the NIC settings for the VM on the recovery network.



Then hit Next through to the summary and verify your settings.


After you click Done, your VPG is complete.  After initial replication, it will let you know if it is meeting your SLA or not.


And that is it.  After this, you just monitor to make sure that your VPGs are meeting their SLAs.  SMTP notifications are available in the site settings.

Not only will it let you replicate Vmware hypervisors (like the examples above), but will also work with Hyper-V, Azure, and AWS.  Really solid technology, with a very simple setup and configuration.
