Four versions of the Exadata Database Machine X7-2 are available – the Full Rack, Half Rack, Quarter Rack, and Eighth Rack – depending on the size, performance and I/O requirements of the database to be deployed. One version can be expanded online to another ensuring a smooth upgrade path as processing requirements grow.
Eighth Rack is the minimum Exadata configuration. Eighth Rack database servers have one processor each with all cores enabled. Maximum memory supported per database server is 768GB. Eighth Rack EF storage servers have half the cores and flash drives enabled. Eighth Rack HC storage servers have half the cores enabled and half the disks and flash cards removed. The optional NIC is not available for the Eighth Rack
