Exadata Hardware

The Exadata Database Machine is a pre-configured, fault-tolerant, high-performing hardware platform built using industry-standard Oracle hardware. The Exadata hardware architecture consists primarily of a compute grid, a storage grid, and a network grid. Since 2010, the majority of Exadata customers deployed one of the four Exadata X2 models, which are comprised of Oracle Sun Fire X4170 M2 servers in the compute grid and Sun Fire X4270-M2 servers running on the storage grid. During Oracle Open World 2012, Oracle released the Exadata X3-2 and X3-8 In Memory Database Machines, which are built using Oracle X3-2 servers on the compute and storage grid. In both cases, Oracle runs Oracle Enterprise Linux or Solaris 11 Express on the compute grid and Oracle Linux combined with unique Exadata storage server software on the storage grid. The network grid is built with multiple high-speed, high-bandwidth InfiniBand switches.
