Replication in WMware vSphere 5.5

Posted: October 14, 2015 in VMWare

VMware vSphere Replication is a hypervisor-based, asynchronous replication solution for vSphere virtual machines. It is fully integrated with VMware vCenter Server and the vSphere Web Client.

vSphere Replication is provided in open virtualization format (OVF) or with a standard vCenter Server installation.OVF consist of vSphere Replication Server and components being used to administer and manage vSphere replications.With vSphere Replication, you can replicate virtual machines from a source datacenter to a target site quickly and efficiently

OVF appliance can be freely downloaded here,with your VMWare account

After downloading,right click your cluster in vSphere Web Client and choose deploy OVF template

Browse to downloaded OVF file and click next

Accept EULA,provide a name,select appliance location,datastore.destination network,IP protocol,if you choose static IP allocation provide DNS,Gateway and subnet mask info and set root passwordReview service binding information and verify that Binding status is OK and click finish.

After successfuly deployement,open console and check if applianced has booted properly:

Restar vCentar server (in my case i restarted vCenter appliance)

After restart click on vCenter Server,click manage tab,you shoud see vSphere replication tab.Click on it,click Replication Servers,you should see replication appliance

In this example we’ll migrate xp VM from one datastore to another.Please,take note that i am doing this in lab environment,in the real world,we would transfer VM to another vCenter server.

Right click on running VM and select AllvSphere Replication Actions-Configure replication

Untitled

Select replicate to a vCenter Server

Untitled4

Select vCenter server,i used same vCenter server i am logged in,in real time environment we would use another vCenter server.

Untitled5

Select vSphere replication server,which will conduct migration (in this case our OVA imported template)

Untitled6

select datastore on destination vCenter where VM shold be replicated to

Untitled7

Configure replication for VM.With a Recovery Point Objective (RPO) value we determine the maximum data loss that can be tolerated.If we set the RPO to 10 minutes,it means that vSphere Replication can tolerate losing the data for up to 10 minutes.In our example,the latest available replication instance can never be in a state that is older than 10 minutes. A replication instance refers to the state of a virtual machine at the time the replication starts.We can also enable multiple snapshot instances (Point in time instances) .

Click next and finish.

Click on vCenter Server-Monitor-vSphere Replication-outgoing replication

Untitled

If we want to configure additional recovery point,right click on VM and choose Sync now

Recovering VM

To quickly recover recent version of VM,select vCenter server that vSphere Replication appliance is registered to from left sidebar-Monitor tab-vSphere Replication-incoming replication.

Select powered off VM,right click and choose recovery

Untitled10

Synchronize recent changes-Performs a full synchronization of the virtual machine from the source site to the target site before recovering the virtual machine,only available if the data of the source virtual machine is accessible

Use latest available data- Recovers the virtual machine by using the data from the most recent replication on the target site, without performing synchronization. Use this option if the source virtual machine is inaccessible or if its disks are corrupted.
