In the previous blog, we talked about the concepts behind virtual data optimizer (VDO) and how to configure it with Red Hat Enterprise Linux (RHEL) 7.5 Beta.  In the last step, we created a VDO volume.

In this blog we are going to experiment and observe real world savings on storage. For the experiment, I am not going to use any artificially generated workload but, rather, we’ll follow the simplest way by introducing some data on the disk and then multiplying the same data on the disk with a different name. This simple exercise can ensure that we are adding redundant data to disk to trigger deduplication.
