@Amir Riaz

While everyone is entitled to an opinion, it seems yours is not based on any experience with Exadata, correct? So to say Oracle and Exadata are an OLTP system seems a bit ignorant given the numerous data warehousing technologies that specifically exist in both the Oracle Database and Exadata (and of which Teradata does not have). My recent experience with customer POCs on both Teradata and Exadata (Oracle Database Machine) show that a 1 rack Oracle DB Machine can outperform an EDW Teradata 12 node 1200 HDD system, and somehow I really doubt that 12 nodes of Teradata is cheaper than a single rack of Oracle DB Machine, unless obscene discount rates are being applied (though two can play that game as well). Certainly some of that has to do with Exadata V2′s EHCC (Hybrid Columnar Compression) which has far superior compression (and thus increasing logical disk scan rates) over Teradata’s dictionary compression (max 255 per column which must be specified at table creation time) but mostly it has to do with the poor disk throughput rates Teradata has because of the lack of sequential I/O it does, which Exadata exceeds at as well as the addition of Exadata Flash Cache. Also, if you want to cite some Teradata FUDpaper, save us both the time, especially one as factually inaccurate and outdated as that one.

I have worked with oracle and teradata both. although both technologies are wonderful but i still feel oracle and exadata are oltp system. my recent experience with exadata shows that teradata is still alot faster than exadata under the same price tag. also see teradata paper.

exadata is still oracle.

the points described in this papers really hold waits. how oracle justified it

@Alex

For a presentation given by Tom Kyte:-

“North America Enterprise Technology Centers (ETC)

Atlanta, GA
Two HP Oracle Database Machines, each with 8 database server nodes and 14 HP Exadata Storage Server cells holding 12 drives of 1 TB in size each
Capacity of about 46 TB of uncompressed data / rack

Reston, VA
Three HP Oracle Database Machines, each with 8 database server nodes and 14 HP Exadata Storage Server cells holding 12 drives of 300 GB in size each
Capacity of about 14 TB of uncompressed data / rack

A queue has already formed!”

One would presume that there are plans afoot for similar facilities to be made available in Europe (?)

Great to hear that the product is catching on .Just curious if there is a plan to have sort of a “customer center” where the potential clients can test their apps as part of the sales cycle ? I think there was a similar center for RAC.

Impressive to think that this is only the first generation of the technology . . .
