Database storage

[Roshan]

Hello,

I would like to know what storage option would be most suitable to house our databases.

We have around 10 critical databases(on VM) around 15-20T

The database versions are 12c, 11.2.0.4 and one database which is on 10g. The OS is Red Hat Linux. The ERP databases are AIX and DB version is 11.1.0.7

We are planning to migrate the databases on Oracle Exadata

http://www.oracle.com/technetwork/database/exadata/exadata-technical-whitepaper-134575.pdf

This will also allow us to to setup RAC for these databases on Exadata.

Can you please advise us if there is another storage which is much better than Exadata.

Regards,

Roshan

Exadata is not a storage. It is an engineered system. It has both db nodes and storage nodes inside of it.
db nodes are called compute nodes.
storage nodes are called cell nodes.

Read my blog posts about it.. You will have an idea. (just searc the keyword "Exadata" in my blog, and you will find several articles about it)

Also I did a tech review for Exadata in ITcentralStation.

Exadata is the best option for Oracle Databases..

What is your view on the Oracle supercluster?

I see from the link below it combines the power of Oracle Exadata with integrated application tier.

It is like a SPARC-powered Exadata configuration.
It is not so commonly used .. (Exadata is more common)

It has Exadata Cells and the optimizations that you normally have in  Exadata.

Here is what Oracle suggests;

For customers currently running Oracle Database (or other databases) in mission-critical deployments on UNIX/RISC platforms (such as Power, SPARC or Itanium), SuperCluster would be the natural first candidate because of it's familiarity, technical similarity and feature set.  Conversely, customers running Oracle Database with Oracle Real Application Cluster (RAC) in commodity x86 server environments will likely find the Exadata X-series configurations to be the most natural first choice.

I suggest you to read the following article as well;
