2368 Compute Cores

2.6 Petabytes Uncompressed Storage


Balanced and Optimized

• Custom systems do not achieve full performance

• Component imbalance, misconfiguration, bottlenecks

• Exadata is engineered and optimized end-to-end

• Double-digit GB/sec transfers from disk to database

• DB libraries optimized with firmware, drivers, OS, network

• Years of tuning

• Move I/T talent to higher value business needs

• Not designing, tuning, maintaining hardware configsOptimized

End-to-End

Keys to Speed and Cost Advantage


Exadata Hybrid Columnar Compression

Exadata Intelligent Storage Grid

Exadata Smart Flash Cache

• Data Intensive processing runs in Exadata Storage Grid

• Filter rows and columns as data streams from disks (112 Intel Cores)

• Example: How much product X sold last quarter

• Exadata Storage Reads 10TB from disk

• Exadata Storage Filters rows by Product & Date

• Sends 100GB of matching data to DB Servers

• Scale-out storage parallelizes execution and

removes bottlenecks

Exadata Intelligent Storage GridMost Scalable Data Processing



Exadata Intelligent Storage

• Exadata storage servers also run more complex operations in storage

• Join filtering

• Incremental backup filtering

• I/O prioritization

• Storage Indexing

• Database level security

• Offloaded scans on encrypted data

• Data Mining Model Scoring

• Smart File Creation

• 10x reduction in data sent to DB servers is common

Exadata Intelligent Storage Grid

Exadata Hybrid Columnar CompressionHighest Capacity, Lowest Cost


• Data is organized and compressed by column

• Dramatically better compression

• Speed Optimized Query Mode for Data Warehousing

• 10X compression typical

• Runs faster because of Exadata offload!

• Space Optimized Archival Mode for infrequently accessed data

• 15X to 50X compression typical

Exadata Smart Flash CacheExtreme Performance OLTP

• Exadata has 5 TB of flash

• 56 Flash PCI cards avoid disk

controller bottlenecks

• Intelligently manages flash

• Smart Flash Cache holds hot data

• Gives speed of flash, cost of disk

• Exadata flash cache achieves:

• Over 1 million IO/sec from SQL (8K)

• Sub-millisecond response times

• 50 GB/sec query throughput

Unified Hardware, Specialized Software


• Exadata enables a single hardware architecture for all database needs

• Massively parallel hardware, InfiniBand, & Flash are best for all DB applications and workloads

• Enables Strategic building block approach to IT

• Domain specialization is in software, not hardware

• Oracle offers the most sophisticated specializations

• Analytics.

• OLAP, Statistics, Spatial, Data Mining, etc.

• Warehousing

• Flexible Partitioning, Bitmap Indexing, Join indexing, Materialized Views, Result Cache

• Data

• Relational, XML, Objects, Secure Files

• OLTP, Security, HA

DBFS - Scalable Shared File System


• Database Machine comes with DBFS shared Linux file system

• Shared storage for ETL staging, scripts, reports and other application files

• Files stored as SecureFile LOBs in database tables stored in Exadata

• Protected like any DB data – mirroring, DataGuard, Flashback, etc.

• 7+ GB/sec file system I/O throughput

• 5 TB/hour data loading using DBFS and parallel load
