Highly powerful engineered Machine
Use Cases and Deployment Scope
We used Oracle Exadata to consolidate our enterprise databases on single platform . It provides low latency , excellent performance for any kind of applications. Both OLTP and OLAP application databases were hosted . It provides high redundancy and very good fault tolerance
Pros
- Low latency 10X performance
- Various compression features
- Flexible configuration based on needs
- Smart Scan , Flash storage , Storage indexing
Cons
- Too expensive
- Integration with third party
Return on Investment
- Pretty expensive
- Best to consolidate all our databases in one machine
- Most powerful machine
Usability
Other Software Used
Oracle Database, Oracle ZFS, NetApp StorageGRID, VMware vSphere
Excellent Uniquely Designed DB Machine
Use Cases and Deployment Scope
Various database servers for Healthcare applications. Use cases span from typical transactional systems to data warehouse and analytics. Important criteria: database performance, data safety, 24x7 non-stop operations, High Availability. These are critical for real-time applications serving customers in healthcare industry.
Pros
- High speed of SQL operations due to a unique design of Exadata with offloading of SQL processing to storage cells
- Built-in High Availability of a DB server due to it's base architecture of a multi-node Oracle Real Application Cluster
- High overall sever performance due to its use of a proprietary "Smart Cache" feature utilizing a high speed flash memory
- Excellent scalability of a DB server by adding cluster nodes as well as expanding it into a network of serially connected clusters
Cons
- The process of patching and upgrade of Exadata server components could be improved with a goal to minimize the overall effort, make it fully automated and transparent.
- Improved guidelines and possibly more sophisticated tools for sizing of new Exadata servers for migration from old legacy hardware.
Return on Investment
- One of the central critical systems was migrated from a large 4-node Oracle RAC running on legacy hardware. This application was experiencing severe performance issues literally causing loss of service for numerous customers. Once it was migrated to a 2-node Exadata server, its average performance improved almost by a level of magnitude, therefore eliminating any signs of application slowness.
- Numerous application databases were migrated to Exadata servers which reduced the overall cost of hardware due to Exadata's price structure.

Exadata does better than most
Pros
- RAC/clustered database technology
- RMAN duplicate and cloning
- Full sh/bash/ksh support
- Generally faster i/o throughput versus non-exadata
Cons
- Patching can often become quite involved and convoluted. It should be more transparent and straightforward.
- Storage metrics can be difficult and time consuming to obtain.
- Basic administrative functions can be hard to repair when discovered.
- Vendor support can take a while to obtain. Generally several attempts are necessary to reach the right area of vendor expertise.
Return on Investment
- Unfortunately Exadata can be extremely high cost, especially for the higher tiered levels of support.
- It does well in needed only a few machines to build and support hundreds of discrete databases.
- Patching can be burdensome and negate cost savings as the time lost can be considerable.
