Exadata, by Oracle, is an engineered system designed to provide optimized performance, availability, and scalability for enterprises running Oracle databases. It serves as a solution for organizations seeking to manage large amounts of structured and unstructured data effectively, in an era where data-intensive applications are increasingly prevalent. The primary purpose of Exadata is to deliver fast and reliable data processing, allowing businesses to make data-driven decisions more swiftly and accurately.

This versatile system is widely adopted across various sectors, including finance, healthcare, and telecommunications, to handle tasks such as online transaction processing (OLTP), data warehousing (DW), and in-memory analytics. One key aspect of Exadata revolves around its unique architecture which combines high-performance hardware with state-of-the-art software to enable efficient and seamless data management. This harmonious integration leads to reduced latency, increased throughput, and improved resource utilization.

The Exadata platform incorporates intelligent storage servers known as Exadata Storage Cells which work in tandem with its Smart Scan technology, enabling the system to offload intensive processes and only retrieve relevant data from the storage tier. Moreover, Exadata’s hybrid columnar compression technology significantly reduces the database storage footprint without compromising on performance. As a result, organizations can leverage Exadata’s capabilities to achieve unparalleled performance whilst reducing their operational costs and complexities, ultimately harnessing the true power of their data for business growth and innovation.

Examples of Exadata

Exadata is a combined hardware and software platform developed by Oracle Corporation that provides excellent performance, extreme scalability, and tight integration with Oracle Database. It is designed to run mission-critical and data-intensive applications for various industries. Here are three real-world examples of Exadata technology implementation:

Telefonica: In 2012, the telecommunication giant Telefonica migrated their billing databases to Oracle Exadata Database Machine. The move allowed them to streamline their operations, resulting in reduced total cost of ownership (TCO) and an increase in performance while minimizing the risk and complexity of their infrastructure. Telefonica reported a 40% decrease in total billing procedure time, allowing them to provide better service to their customers and handle a higher volume of transactions.

CERN: The European Organization for Nuclear Research (CERN) operates the Large Hadron Collider, one of the world’s most technologically advanced scientific instruments. They use Oracle Exadata to store, process, and analyze vast amounts of data generated through their experiments. With Exadata’s high-performance capabilities, CERN has been able to analyze data collected from billions of particle collisions – enabling them to make groundbreaking discoveries, such as the Higgs boson particle.

Airtel: Bharti Airtel Limited, one of the leading global telecommunications companies, has implemented Oracle Exadata to improve the performance of its customer relationship management (CRM) and enterprise resource planning (ERP) applications. The adoption of Exadata enabled Airtel to deliver a faster and more seamless customer experience. It also helped to enhance the efficiency of their data centers and reduce operational costs, enabling them to handle and analyze vast amounts of data crucial to better understanding customer needs and preferences.

Exadata FAQ

What is Exadata?

Exadata is an Oracle-engineered platform that combines database servers, storage servers, and networking within a unified system optimized for high-performance running of Oracle databases. The primary goal of Exadata is to deliver top-tier performance, scalability, and availability for Oracle databases.

What are some key features of Exadata?

Some key features of Exadata include Smart Scan, Hybrid Columnar Compression, In-memory processing, and High performance. Additionally, the platform provides advanced systems for high availability, reliability, and scalability.

What is the difference between Exadata and regular Oracle Database?

While Exadata runs Oracle Database, it is a specialized, high-performance platform engineered to optimize database performance and eliminate the limitations of traditional database systems. By combining storage, compute, and networking in a single platform, Exadata can provide unparalleled database performance, seamless scalability, and high availability.

How does Exadata improve query performance?

Exadata uses Smart Scan technology to offload query processing to the storage layer, improving query execution times significantly by reducing the amount of data transferred between storage and database servers. By performing query tasks at the storage layer, only relevant data is sent to the database server, which reduces overhead and improves performance.

What is Hybrid Columnar Compression in Exadata?

Hybrid Columnar Compression (HCC) is a data storage technique used by Exadata to compress data storage significantly without sacrificing performance. HCC utilizes a combination of row and columnar storage techniques, providing optimal compression ratios while maintaining query performance. This technology allows Exadata to store more data within the same storage capacity and reduces the required storage footprint overall.

How does Exadata ensure high availability?

Exadata is designed with various high availability features to ensure that your Oracle Database remains up and running even in the event of hardware failures. Some of the high availability features include redundancy at both the hardware and software levels, data protection with Oracle Data Guard, automatic storage management with Oracle ASM, and integration with Oracle RAC (Real Application Clusters) for seamless failover between database nodes.

Can Exadata be deployed on-premises or in the cloud?

Exadata can be deployed both on-premises and in the cloud. Oracle offers Exadata in various consumption models such as the Oracle Exadata Cloud Service (ExaCS) for cloud deployments or as Oracle Exadata X8M for on-premises installations.
