2.1.1.4 Eighth Rack X4-2 and X5-2 Expansion Options

Oracle Exadata Database Machine Eighth Rack X4-2 and X5-2 contains fully configured servers, with approximately half of the available system resources (CPU, RAM, and storage) disabled. Consequently, Eighth Rack to Quarter Rack expansion of X4-2 or X5-2 systems is done using software only to enable the disabled hardware resources. Expansion beyond a Quarter Rack requires additional expansion kits, which contain additional hardware.
