What is Enhanced Testing?

Enhanced testing is a new feature in version 3.2 of the Cristie Virtual Appliance that allows the user to test replications without affecting them.

Enhanced testing adds a virtualization layer between the source and target system of a replication. This allows access to the data that has already been transferred to the target without stopping the replication.
There are two ways of using Enhanced Testing; either to a VMware Hypervisor or directly to an Enhanced Testing environment.

Using Enhanced testing with VMware

To use enhanced testing you will need to first create a Replication job and add a machine, selecting a VMware environment as the target.

Click the cog icon to expand the machines configuration and open the Enhanced Testing tab.

When you enable Enhanced Testing, you will get further options to customise the way Enhanced Testing works.

Here you can assign a VLAN to the test VM, so the booted VM can be isolated from your production environment.

A snapshot area is allocated on the storage devices that store the changed information. This information is merged down to the recovery area once a sync completes.

Initial clones are written directly to the recovery partition and subsequent syncs are written to the snapshot area.

Snapshot areas can be allocated 2 ways; as a percentage of the overall target disk or a fixed value of the target disk. This is customised on a per disk basis. There is also an option to add the snapshot area to the disk (available for VMware targets only), this increases the target disk size to store the snapshot information instead of reducing the recovery area.

Using Enhanced Testing directly

You can customise the Enhanced Testing ISO via boot management (more information).
Booting the Enhanced Testing ISO on a system allows you to take advantage of Enhanced Testing on Physical and Virtual targets.

Once you have booted the Enhanced Testing ISO you can select it as the target of a replication by selecting Show available enhanced testing environments.

You will then be able to configure Enhanced Testing as documented above.
