Improvements to My Organization

Because of Exadata Systems, we were able to consolidate all the applications databases into one, e.g, Oracle EBS, Siebel, Hyperion etc.

Room for Improvement

Exadata Linux systems have Intel CPUs inside. I would suggest that if Oracle could work together with Intel to have some more intelligence at the CPU level, then there would be nothing like it.

Use of Solution

I've been using it since June 2013.

Deployment Issues

We didn't have any deployment issues.

Stability Issues

After three to four months we may need to perform a rolling reboot of the DB/storage servers.

Scalability Issues

I would say it's the best solution in terms of scalability.

Customer Service and Technical Support

Customer Service:

8/10.

Technical Support:

9/10.

Previous Solutions

We used both EMC Storage and IBM Servers.

Initial Setup

The setup was simple, however, the database migration was a bit challenging, but there was no show stopper anywhere.

Implementation Team

We are a vendor TCS (Tata Consultancy Services) and have as a customer the Taj Group of Hotels (IHCL), where we deployed and implemented Exadata Systems.
