Oracle Exadata Machine
Exadata is a combination of hardware and software working closely together. The hardware itself is not something special. Most of the performance improvement comes from how the components are integrated and the smart software used at the storage layer.
EXADATA OVERVIEW
- Fully integrated platform for Oracle Database
- Based on Exadata Storage Server storage technology
- High-performance and high-availability for all Oracle Database workloads
- Well suited as a database consolidation platform
- Simple and fast to implement (Pre-configured, Tested and Tuned for Performance)
Why Choose Exadata?
Exadata Database Machine is purpose-built to solve the most common and challenging issues faced in real-world Oracle Database environments.
Data Warehousing Issues
- Supports very large, complex, and long-running queries
- Efficiently manages multi-terabyte and even petabyte-scale databases
OLTP Issues
- Supports very large user populations and high transaction volumes
- Delivers consistently quick and predictable response times
Consolidation Issues
- Efficiently supports mixed workloads (OLTP + OLAP/analytics) on the same system
- Intelligent workload prioritization using I/O Resource Management (IORM)
Configuration & Operational Issues
- Eliminates the challenge of creating balanced configurations without performance bottlenecks
- Removes complexity in building and maintaining a robust, high-performing system
Redundant & Fault Tolerant Architecture
- Tolerates failure of any individual component (no single point of failure)
- Data is automatically mirrored across multiple Exadata Storage Servers
- Ensures continuous availability even during hardware failures
