This is an illustration of the key components in an Oracle Exadata Database Machine environment.
The system is represented by multiple layers of objects, each in a row, arranged from top to bottom. The top layer is a row of database servers, with key components illustrated. The middle layer is the RDMA Network Fabric, which is represented by lines connecting the database server layer to the storage server layer (the third layer). The storage server layer shows individual storage servers (cells), with key components of each storage server illustrated. Each storage cell contains a group of disks that represents the physical storage.
The components highlighted in the database servers and storage cells are described in the text that follows the image.
