What is most valuable?
Oracle Engineered Systems are the best solution for Oracle and non-Oracle applications: hardware and software are combined together to ensure high availability and maximum performance. Oracle Exadata contains all the advantages of standard Oracle Database, but on top of that there are exclusive features such as IORM (IO Resource Manager) and HCC (Hybrid Columnar Compression). IORM (in combination with Database Resource Manager (DBRM)) permits you to isolate I/O requests to avoid I/O saturation. HCC provides different levels of compression to reduce space allocation and to decrease I/O.
How has it helped my organization?
Oracle Exadata and Oracle Exalogic are standard-based. Customers can easily migrate their existing applications based on Oracle Database and Oracle WebLogic: they can take advantages of Engineered Systems with minimal effort during the migration process. Customers can benefit from high performance without modifying Java or SQL code and they can decide to use specific features after migrating to Exadata/Exalogic. Also, Engineered Systems can be used to consolidate complex environments: for example, our customer was able to decommission about 20 blades, using a single 1/8 Exalogic x4-2. Finally, Exadata and Exalogic simplifies patching/upgrading process, unifying firmware upgrades, ILOM upgrades, OS patching, Database/WebLogic upgrade/patching in one "single-vendor" activity.
What needs improvement?
EMOC (Oracle Enterprise Manager Ops Center) is not very user-friendly, the user interface could be improved.
For how long have I used the solution?
We installed the first Exalogic in 2013.
What do I think about the scalability of the solution?
It provides a standard procedure to scale the number of compute/storage nodes.
How are customer service and technical support?
Which solution did I use previously and why did I switch?
There was no solution in place previously.
What's my experience with pricing, setup cost, and licensing?
Using Exadata and Exalogic, you can get the best performance optimizing the number of CPUs, saving costs on software licensing. Also, if you consolidate your environment using Engineered Systems, you can save money on hardware (storage/compute capacity).
Which other solutions did I evaluate?
No other options were looked at.
What other advice do I have?
As best practice, before starting the installation you should have a look at the Oracle Documentation. Oracle provides a "Getting Started Guide" to get up-to-date checklists to verify requirements (for example IP addresses, name syntax, etc.) and to be sure your infrastructure is ready for the installation. Also, we recommend to install Oracle Enterprise Manager as a monitoring solution: it is fully integrated with Oracle Exadata and Oracle Exalogic, you can monitor hardware (compute nodes, switches, ILKOM etc.) and software (operating system, Database, WebLogic, business applications etc.).
