For our tests, we deployed a four-server, software-defined data center (SDDC) from our VMware Cloud on AWS portal.
The servers of the SDDC used Intel Xeon E5 2686 v4 processors running at 2.30 GHz with 512 GB of RAM. Each processor had 18 cores and 36 logical threads with hyperthreading enabled (Figure 1).

On VMware Cloud for AWS, vSAN is used for the storage. It used the 8 NVMe devices that were in each of the four servers. Each NVMe had a capacity of 1.7 TB, so the entire cluster had 32 NVMe devices and a total raw capacity of approximately 40 TB (Figure 2). Deduplication and compression features of vSAN are enabled on VMware Cloud on AWS which will provide additional effective capacity. As part of the automatic deployment, management and workload datastores are created. The management datastore is for things like the vCenter and NSX-related VMs. The workload datastore is where all the VMs that are created or migrated into the environment are stored. This is where all the Oracle database VMs that were created for these tests were stored.

Figure 3 shows a four node SDDC on AWS and its major components. We configured only the VMs that comprised the Oracle database and load driver. The rest of the components and configuration were done automatically as part of the deployment from the VMware Cloud on AWS portal.
