What is Exadata rack?
Exadata storage provides an advanced compression technology, Hybrid Columnar Compression, that typically provides 10x, and higher, levels of data compression. The Exadata Storage Expansion Rack enables the growth of Exadata storage capacity and bandwidth for X2-2 and X2-8 Exadata Database Machines.
What is the core count for each CPU in the Exadata X8 2 database server?
16-core
3 Exadata Storage Server X8-2 Servers, either High Capacity or Extreme Flash. Each server has 2 x 16-core processors, each with 8 cores enabled. High Capacity (HC) storage servers have 2 PCI flash cards, each with 6.4 TB (raw) Smart Flash Cache and 6 x 14 TB 7,200 RPM high capacity disks.
Why is Exadata so fast?
The Smart Flash Cache intelligently caches key data to minimize physical I/Os. The second key feature that contributes to the speed of Exadata is the use of an advanced database compression feature called Hybrid Columnar Compression, which lets the database compress data at 10x times the original data.
Is Exadata a database?
