ORACLE EXADATA
Introduction
Exadata is a Database Appliance containing a Storage Server which is database aware,
Exadata was
announced by Larry Ellison at the 2008 Oracle Open World conference in San
Francisco for immediate delivery. The main headline was that Oracle was
entering the hardware business with a pre-built database machine, engineered
by Oracle. The hardware at this time was manufactured, delivered and
supported by HP. Since the acquisition of Sun Microsystems by Oracle circa
January 2010, Exadata used Sun-based hardware. In August 2011, Oracle
announced that Exadata database machines would be orderable with Solaris 11
Express (in addition to Oracle Linux).
So it's a database appliance containing a Storage Server which is database aware,
hence it provides the fastest medium to reduce I/O and ensures that only
required blocks travels between Storage Server to Database Servers.
Exadata has an infiniband to communicate between storage
server and database machine and infiniband provides a 40Gbps communication.
