Architecture design includes various aspects of the solution such as components of physical layer, software layer, and storage volumes design. The architecture was designed to broadly represent the infrastructure that customers use for their Oracle databases. Two nodes of Dell PowerEdge R750xs servers were used for the compute layer, and a single PowerStore 5000T was used for storage needs.
This two-node architecture is built to provide a high availability design. It can be extended to three or more nodes to consolidate more databases.
The server layer consists of database ESXi servers and two R750xs PowerEdge servers running ESXi 7.3 hypervisors for four VMs running Red Hat Enterprise Linux 8.5 guest operating system. Only one of the two servers is actively used for benchmarking and the second server is reserved for high availability.
Each ESXi server consists of:
The network layer consists of the following types of connectivity:
The networks are implemented with the following switches:
The storage layer consists of the PowerStore T array as the FC SAN storage for databases and the data stores for VM operating system volumes.
