1 Barry Hodges Senior Solution Architect, Sales Consulting, Oracle NZ The Best of Oracle Open World 2008

2 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

3 Setting the scene …

4 Data Warehouses Growing Rapidly Tripling In Size Every Two Years Source: Winter TopTen Survey, Winter Corporation, Waltham MA, Actual Projected Terabytes of Data Size of the Largest Data Warehouses

5 Data Warehouses Start Slowdown at 1TB Table Scan Time Table Size 1TB10 TB100TB 1 Hour 10 Hours 5 Hours Typical NAS Typical Mid-Range Array Typical High-End Array

6 The Performance Challenge Storage 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

7 Ship less data through the pipes Add more pipes Make the pipes wider Solutions To Data Bandwidth Bottleneck

8 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 Solution Approaches

9 What We Announced …

10 HP Exadata Storage Server Hardware The 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

11 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

12 8 GB DRAM Redundant 110/220V Power Supplies 2 Intel 2.66 Ghz Xeon Quad-core Processors Infiniband DDR dual port card Lights Out 100c – Management Card 12 x 3.5 Disk Drives RPM 1000GB SATA RPM 450GB SAS Cell Hardware Details – HP DL180G5 P400 Smart Array Disk Controller card - 512M battery backed cache

13 SAS or SATA Disks in Exadata Servers Choice of either –300 GB 15,000 RPM Serial Attached SCSI (SAS) disks –1 TB 7,200 RPM Serial Advanced Technology Attachment (SATA) disks SAS AdvantagesSASSATAAdvantage Throughput (MB/s)1, X Average Seek Time (ms) X Disk level read errors (per year) X Years to disk failure X Choose SATA Based Servers for High Capacity SATA AdvantagesSASSATAAdvantage Capacity (TB RAW) X Capacity (TB Uncompressed User Data)* X Choose SAS Based Servers for High Performance * Computed after mirroring, log files, indexes, undo and temp tablespaces SUPERCEDED

15 Traditional Scan Processing What Were Yesterdays Sales? SUM Oracle Database Grid Storage Array Retrieve Entire Sales Table Select sum(sales) where Date= 20-Oct …

16 Exadata Smart Scan Processing Oracle Database Grid What Were Yesterdays Sales? Exadata Storage Grid SUM Select sum(sales) where Date= 20-Oct … Retrieve Sales Amounts from Oct 20

17 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

18 Graph shows throughput achieved in real-world deployments –Infiniband is held back by PCIe 1.0 x8 bus on typical host systems MB/sec 12x slower 3x slower Single Connection Throughput InfiniBand Throughput

19 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 4 GB/sec 8 GB/sec 16 GB/sec …

20 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 HP Oracle Database Machine Pre-Configured High Performance Data Warehouse * Computed after mirroring, log files, indexes, undo and temp tablespaces

21 Software Components Required Software –Oracle Database 11g Enterprise Edition –Oracle Exadata Storage Server Software –RAC –Partitioning Option Recommended Software –Advanced Compression Option –Enterprise Manager Packs: Diagnostics, Provisioning, Tuning –OLAP Option –Data Mining Option –Advanced Security Option –Real Application Testing –Oracle Business Intelligence Enterprise Edition Plus

27 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

28 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 ExadataNon-Exadata Database Server Online Migration
