On 30 September, 2012, Oracle announced Exadata X3, which will be available in two models, X3-2 and X3-8. In X3-2, important changes include:
The list price of the X3-2 hardware and the storage servers and the storage sizes remain unchanged. (For further X3-2 specifications, see www.oracle.com/us/products/database/exadata/overview/index.html )
X3-2 hardware comes with larger, faster components, including 32 GB more memory per compute node — with no price increase. The change in Intel processors and increase in base memory are predictable upgrades following Moore's law. Gartner is focusing on the X3-2 because we see few changes to the X3-8 at this time.
In the X3-2, the most significant change is the four-fold increase in flash, to a maximum of 22.4 TB, coupled with the FCWB feature. With this increase, Oracle makes a statement — it's time to increase reliance on flash because its performance has improved while the failure risk has dropped. FCWB, which allows data to remain in flash without the need to write it to disk, is available on the X3 plus existing V2 and X2 systems. The increase in flash helps Oracle refute marketing from flash vendors such as Fusion-io and Violin Memory.
The value of larger flash and FCWB depends on the use case for Exadata:
But these advantages have some added costs. Customers will need to buy additional Oracle database management system (DBMS) licenses because each server (compute node) has four additional cores requiring two additional DBMS licenses — approximately $750,000 list price on a full rack (8 nodes) of X3-2, plus related option licenses. Another concern involves the use of many generations in a cluster (e.g., X2 with X3). While the performance of multi-generational configurations will be better than an older, homogenous configuration, some tuning may be required to optimize performance. Balancing workloads across a multi-generational cluster is part manual and part automatic (with RAC) and will be increasingly difficult. As a result, some customers will consider replacing the entire set at significant cost.
