Oracle unveiled the fourth generation of its Exadata X3 systems, which are designed as "in-memory machines" and can now host up to 22.4 TB of data in flash cache.

The new systems are built on top of the hardware knowledge of the former Sun Microsystems and are now marketed as Oracle's highest performing platform for database workloads such as online transactions and data warehousing. The systems can be used with any application certified with Oracle Database 11g R2 and Oracle Real Application Clusters.

Available in two models as X3-2 and X3-8 (2-socket and 8-socket) servers, the systems are available in eighth-, quarter-, half-, and full-rack configurations that integrate up to 160 CPU cores and 4 TB of RAM for database processing and 168 CPU cores for SQL processing in storage in two to eight servers installations. Both models offer up to 224 TB of capacity per rack.

Consumers can choose up to 168 disks that can include 600 GB high-performance or 3 TB high capacity disks. Each storage server also includes 4 PCI flash cards with a total capacity of 1.6 TB, which brings both the X3-8 and X3-2 systems to a total of 56 400 GB PCI flash capacity to 22.4 TB. Oracle said that the cards are designed to automatically host frequently accessed data in the flash cache, while rarely accessed data is moved to HDDs. The uncompressed I/O bandwidth per rack is 100 GB/second.

Pricing was not announced.
