|Exadata: Oracle's database machine|||||Exalogic: cloud computing in a box?|
Oracle Exadata first came out in 2008: Oracle enters the appliance market with Exadata. It was a joint Oracle-HP production.
Curt Monash gave a breakdown of it in this Exadata podcast: Exadata: A first look at Oracle's entry into the appliance market.
Needless to say, it didn't sell well. Though Oracle never released numbers, it was rumored to have only sold a couple dozen units.
Soon after Oracle announced it was acquiring Sun Microsystems, it came out with its second version of Exadata, this time a Sun-based product: Oracle, Sun roll out Exadata Database Machine Version 2 for OLTP.
Companies like R.L. Polk, shown in the video above, migrated to Exadata and have since described the massive query improvements they have seen.
Rivals like IBM, Teradata and SAP were ready for the challenge: Oracle-Sun competitors believe they can 'stack' up. They attacked all angles, including topics like data warehousing, databases and Oracle's integrated stack approach.
After a year, it was clear that Exadata V2 was enjoying more success than the first version: Oracle Exadata Version 2 interest booms a year after release. A short time later, in the fall of 2010, Oracle released Exadata X2-8, a more beefed-up version of Exadata X2-2, which is now the company's name for Exadata V2 (see specs to the left).
One analyst then recently took a deep dive look at Exadata X2-8: Oracle Exadata X2-8 and the evolution of Oracle RAC.
