The Best of Oracle Open World 2008 Barry HodgesSenior Solution Architect, Sales Consulting, Oracle NZ
A Different Perspective • Just being there … • Opportunity to liaise with subject matter experts and product managers • Input into the road map • Pre-arranged agenda adapted as new opportunities presented themselves
1000 800 600 Terabytes of Data Actual 400 Projected 200 1998 2000 2002 2004 2006 2008 2010 2012 Data Warehouses Growing RapidlyTripling In Size Every Two Years Size of the Largest Data Warehouses Source: Winter TopTen Survey, Winter Corporation, Waltham MA, 2008.

The Performance ChallengeStorage Data Bandwidth Bottleneck • Current warehouse deployments often have bottlenecks limiting the movement of data from disks to servers • Pipes between disks and servers are 10x to 100x too slow for data size
Solutions To Data Bandwidth Bottleneck • Ship less data through the pipes • Add more pipes • Make the pipes wider
Solution Approaches • “Brainy Software” approach - use smart database software to minimize the need for hardware • Smart Scan, OLAP, Bitmap Indexing, Join indexing, Materialized Views, Result Caches, Range Partitioning, etc. • “Brawny Hardware” approach - use powerful hardware to perform brute-force scans and joins • Brawny hardware approach only works if the rate of scanning data scales with size of data
HP Exadata Storage Server HardwareThe Core Building Block • Exadata Ships Less Data Through Pipes • Query processing is moved into storage to dramatically reduce data sent to servers while offloading server CPUs • Exadata has More Pipes • Modular storage “cell” building blocks organized into Massively Parallel Grid • Bandwidth scales with capacity • Exadata has Bigger Pipes • InfiniBand interconnect transfers data 5x faster than Fibre Channel Exadata Moves a Lot Less Data a Lot Faster
HP Exadata Cell Building Block Details • Storage Server (Cell) is building block of Exadata Storage Grid • Cells ship with all hardware and software components pre-installed • Runs Exadata Storage Software, Oracle Infiniband protocol, Oracle Enterprise Linux 5.1, and HP hardware management software • Hewlett Packard is exclusive hardware provider • Absolutely no custom hardware - all parts off the shelf high-volume

Smart Scan Functionality • Join filtering • Star join filtering is performed within Exadata storage cells • Dimension table predicates are transformed into filters that are applied to scan of fact table • Backups • I/O for incremental backups is much more efficient since only changed blocks are returned • Create Tablespace (file creation) • Formatting of tablespace extents eliminates the I/O associated with the creation and writing of tablespace blocks • Smart scans are transparent to the application • No application or SQL changes required • Returned data is fully consistent and transactional
InfiniBand Throughput Single Connection Throughput • Graph shows throughput achieved in real-world deployments • Infiniband is held back by PCIe 1.0 x8 bus on typical host systems MB/sec 3x slower 12x slower
16 GB/sec … 8 GB/sec 4 GB/sec Massively Parallel Storage Grid • Scalable • Scales to hundreds of storage servers • Data automatically distributed across storage servers by ASM • Transparently redistributed when storage servers are added or removed • Data bandwidth scales linearly with capacity • Available • Data is mirrored across storage servers • Failure of disk or storage server transparently tolerated • Simple • Works transparently - no application changes Exadata bandwidth scales linearly with capacity
HP Oracle Database MachinePre-Configured High Performance Data Warehouse • 8 HP ProLiant DL360 Oracle Database servers • 2 quad-core Intel Xeon, 32GB RAM • Oracle Enterprise Linux • 14 Exadata Storage Cells (SAS or SATA) • Up to 21 TB uncompressed user data (SAS) * • Up to 46 TB uncompressed user data (SATA) * • 4 InfiniBand switches, 1 Gigabit Ethernet switch • Pre-installed, pre-configured Add more racks for unlimited scalability * Computed after mirroring, log files, indexes, undo and temp tablespaces

Data Protection Solutions • All single points of failure eliminated by the architecture • Hardware Assisted Resilient Data (HARD) built into storage • Prevent data corruption before it happens • Data Guard provides disaster protection & data corruption protection • Automatically maintained second copy of database • Flashback provides human error protection • Snapshot-like capabilities to rewind database to before error • Recovery Manager (RMAN) provides backup to disk • Archiving and corruption protection • Can be used with Oracle Secure Backup (OSB) or third party tape backup software • These work just as they do for traditional non-Exadata storage • Users and database administrator use familiar tools
Database Server Online Migration Exadata Non-Exadata Exadata Co-Existence and Migration • Databases can be concurrently deployed on Exadata and traditional storage • Smart Scan capability only works if the whole tablespace is located on Exadata storage • Online migration if currently using ASM and ASM redundancy • Migration can be done using RMAN or Data Guard
