Hi,

I will continue to explain Oracle Exadata database machine in this post.

 

Read first article before this.

Physical Exadata components in a cabinet are as follows.

 

The layout map of these physical components is as follows in the 42U Exadata cabinet.

 

 

 

We said Exadata Exadata insistently, Well Why should I buy it ?

 

The advantages of Exadata compared to non-Exadata are as follows.

 

 

 

Exadata can be in 4 categories as 1/8, 1/4, 1/2 and Full cabinet according to different size and configuration.

 

Exadata 1/8 and 1/4 inside of the cabinet looks physically the same as 2 Database Server, 3 Storage Server.  Half of the CPU is disabled in the 1/8 Exadata’s and half of the disk is not activated in the 1/8 configuration Exadata according to 1/4 Exadata.

 

 

There are 4 Database Servers and 7 Storage Servers in Exadata 1/2 Cabinet.

There are 8 database servers and 14 Storage servers in a full Exadata cabinet.

 

These quantities are the default values in the standard cabinet and one or more node Database or Storage Server can be added if desired.
