Oracle delivers updated Exadata database appliance for big data and analytics

Oracle Exadata Database Machine X4-8

Oracle has announced the latest addition to its Exadata line of engineered systems for operating database workloads. Based on similar technology to its recently announced elastic compute servers, the new model offers performance levels that previously required dozens of racks of equipment, according to Oracle.

The Oracle Exadata Database Machine X4-8 is engineered to be the highest-performing and most available platform for running the Oracle Database, the firm said. However, it is specifically targeting new workloads such as database as a service (DBaaS) and in-memory database applications using the Oracle Database 12c software announced in June.

Like Oracle’s existing Exadata versions, the new system ships as a ready-built and tested enclosure containing a pair of eight-socket database servers with 14 Exadata Storage Servers and InfiniBand fabric interconnects.

However, the database compute nodes in this Exadata are based on the same technology as the Sun Server X4-4 and Sun Server X4-8 elastic compute servers that Oracle introduced in June. These use a custom Xeon chip, the E7-8895 v2, designed by Oracle and Intel with the ability to dynamically switch core count, clock frequency and power consumption without the need for a system-level reboot.

With these chips, each Exadata Database Machine X4-8 boasts 240 CPU cores and up to 12TB of memory for database processing, backed by up to 672TB of disk storage and 44TB of PCI flash storage. This level of hardware means it can consolidate hundreds of databases and run massive databases entirely in-memory, Oracle said.

Oracle’s Senior Vice President for Systems Technologies Juan Loaiza said: “Exadata Database Machine X4-8 again raises the bar and provides an ideal platform for Oracle Database In-Memory. Together, the combination enables customers to evolve into real-time enterprises.”

The new Exadata Database Machine X4-8 is compatible and interoperable with previously released Exadata systems, enabling existing customers to easily expand as their requirements dictate, Oracle claimed.
