Oracle Exadata Database Machine the Focus of Oracle Spatial User Conference
Jim Steiner, Oracle's VP of Server Technology, opened the Oracle Spatial User Conference by talking about the focus of the event which was "extreme spatial performance and the introduction of Oracle's Exalogic Elastic Cloud and the Exadata Database Machine. Steiner said that the Exadata Database Machine was not just a preconfigured set of hardware, but engineered explicitly to run the Oracle database and handle the most demanding geospatial workloads. He discussed the fact that 15 years ago when Oracle introduced Oracle Spatial it was a "niche technology." "The vision hasn't changed but the technology has evolved and now includes grid computing, "the cloud," virtualization and now database machines; "Oracle has remained true to this vision even with a changing technology landscape," said Steiner.
Another emphasis was to stress how Oracle Spatial is part of the Oracle database kernel and how it is architected to exploit the processing power bandwidth and parallelism of the Exadata Database Machine. Spatial operations can be performed in up to two terabytes of database systems global area memory. Other features of the Exalogic Database Machine is:
- Eight 2-socket database servers
- 96 database CPU cores
- 768 GB database server memory
- runs Solaris
- Database grid: up to 128 Intel cores connected by 40 Gb/second InfiniBand fabric for massive parallel query processing
- Raw Disk - up to 336 TB of uncompressed storage
- Memory - up to 2 TB
- Exadata Hybrid Columnar Compression (EHCC) - query and archive modes available 10x-30x compression
- Storage servers - up to 14 storage servers (168 Intel cores) that can perform massive parallel smart scans. Smart scans offloads SQL predicate filtering to the raw data blocks. This results in much less data transferred and dramatically improved performance
- Storage flash cache - up to 5.3 TB w/ i/o resource managemen
The meeting continues through today and more reports will be forthcoming.
