Next, we created four VMs—one on each of the PowerFlex R840 HCI nodes—for the Hadoop cluster consisting of three virtual machines and the Oracle NoSQL application. We then created two VMs—one on each of the compute nodes—for the Oracle and Microsoft SQL Server database applications.
We used the following design principles and best practices to create the VMs:
