Oracle Exadata

Oracle Exadata is an excellent, very high speed (In terms of compute power, disk read writes and network latency) product, designed by Oracle for maximum throughput and minimum latency on Oracle databases. Exadata is a combination of highly optimized compute and storage hardware together. This is an ideal product for load intensive applications.

ExadataStorage Servers are the storage platform itself which runs Oracle cell services software (cellsrv).
Storage servers used in the Exadata Rack are called as Cell. Exadata Storage cell is used for making storage GRID.
Competitors to Exadata in market have proprietry, complex and highly expensive infrastructure, where Oracle Exadata takes
advantage as it uses industry standard Oracle Database, which is easy to migrate from any platform.
Exadata provides scale-out architecture for both database servers and storage servers which accommodates any size workload and allows to expand small configurations to extermely large configurations flawlessly and at the same time avoid performance bottlenecks and single point of failures.
