Recently, I downloaded an evaluation version of the Vizioncore vEssentials bundle for VMware ESX Server. Included in that bundle are vRanger Pro, vCharter, and vReplicator. In this article, I offer my review of vReplicator. What is vReplicator? What can it do for you? Does it really work? Let’s find out…
While researching third party products for my new Train Signal VMware ESX Server video series, I spent some time with Vizioncore’s product line. I was impressed at the breadth of products that they offer. They offer over 7 different virtualization products for VMware ESX Server. That is a larger virtualization product line than I can recall being offered by any other company.
vEssentials is one of their most popular bundles and it includes vRanger Pro. vRanger Pro is Vizioncore’s most popular product. Also included in the bundle is vCharter and vReplicator. Here is a breakdown of the vEssentials product bundle:
Let’s say that, today, you want to replicate a VMware ESX Server Guest OS over to another ESX Server. What would you do? I suppose you could create a script that would snapshot the Guest VM then copy the entire Guest VM virtual disk to another ESX Server. However, how long would it take to create that? And why copy the ENTIRE guest virtual disk every night? That could be 10+ GB! And what if it was across a WAN? Truthfully, using a true replication solution is the only answer. Plus, after you see vReplicator in action, I believe you will clearly see that vReplicator is the best Virtualization replication solution available.
So what is vReplicator? vReplicator is host-level replication solution built just for VMware ESX Server & VMware Infrastructure. With vReplicator, you can replicate a VMware ESX Server guest OS (virtual disk) from one ESX Server to another. Once the initial replication is done, only the changes will be sent after that.
Here are some of the additional vReplicator features:
vReplicator is a simple looking Windows application and its operation is easy. After telling vReplicator what ESX hosts you have on your network, all you need to do to replicate an ESX Guest OS from one ESX host to another is to select the source and destination.
Here is a screenshot from vReplicator, showing one of the new replication jobs I created:
As you can see, you can schedule the replication job to run every hour, day, or whatever time interval you want to specify. Additionally, you can “test” the job to see what the results would be. Full reporting of the results of all jobs that have been run can be found in the Reports section or if you watch a job run “live”, you can see the results immediately.
In fact, here is what a running job looks like:
I know that I have already described how vReplicator works but let’s take a look at a diagram:
As you can see, the vReplicator server sits in the middle. It contacts the Virtual Center server to set up snapshots of the ESX host systems. The vReplicator server then compares the differences between the virtual guest OS’s on each ESX host and performs the replication.
In summary, I was very impressed with vReplicator. It did exactly what it claimed to do, it was easy to install, and simple to perform replications of ESX guest virtual machines from one ESX host to another. As I did, I encourage you to try out the free evaluation version of the vReplicator for VMware Infrastructure. You can download either vReplicator by itself or you can find it in the vEssentials Bundle. Please checkout my video demonstration of the vEssentials suite at the Vizioncore website.
