4 Slabé miesta súčasných systémov Úzke miesto Obmedzená dátová priepustnosť medzi storage a DB servermi

5 Priebeh a spracovanie dotazu: Využitie tradičného úložiska Aký bol náš včerajší predaj? Databázový server SELECT príkaz Tradičný Storage Array Načíta celú tabuľku SALES SUM Storage posiela 1TB

6 Ako riešiť obmedzenú priepustnosť? Viac kanálov Širšie kanály Posielať menej dát cez kanály

7 Priebeh a spracovanie dotazu: Využitie Oracle Exadata Aký bol náš včerajší predaj? Oracle Database Grid SELECT príkaz Storage Grid Spracuje príkaz SUM Storage server prehľadá 1 TB a na server pošle 1 GB

11 Exadata Innovations Intelligent storage Scale-out InfiniBand storage Smart Scan query offload Hybrid Columnar Compression 10x compression for warehouses 15x compression for archives Smart PCI Flash Cache Accelerates random I/O up to 30x Triples data scan rate Data remains compressed for scans and in Flash uncompressed compress primary DB Benefits Cascade to Copies standby test dev backup Oracle Corporation

12 Exadata for SAP Certification announced June 10, 2011

13 SAP Applications with Oracle Exadata Presentation Application Database SAP Instances SAP ECC 6.0 SAP Instances SAP BW 7.x SAP Instances SAP BW 7.x

14 Exadata Storage Expansion Rack Big Data for Less Expands storage capacity of existing Exadata Database Machines and SuperCluster Available with either 600GB High Performance disks or 3 TB High Capacity disks Essentially Database Machine with database servers replaced by more Storage Servers For Unbalanced Applications that need more space but not more compute On-disk Backups (up to 27 TB/hour) Historical or Archive Data File Data, LOBs, XML Data, Documents Images, and other large unstructured data

15 Exadata Storage Expansion Racks Expand Database Machine Storage Capacity Online Quarter Rack Half Rack Full Rack Multi Rack 8+ Racks Up to 144 TB Disk Up to 324 TB Disk Up to 648 TB Disk 1.5 TB Flash 3.4 TB Flash 6.75 TB Flash 4 Storage Servers 9 Storage Servers 18 Storage Servers 48 CPU cores 108 CPU cores 216 CPU cores Database Backups, Historical Data, Files, Images, XML InfiniBand Connected

16 Exadata X2-2 Memory Expansion Kit Optional kit for X2-2 customers who consolidate large numbers of databases and require more memory Changes memory configuration of the X4170 M2 database server from 96Gb (12 x 8 GB) to 144 GB (18 x 8 GB Minor reduction in performance due to lower memory bandwidth Adding memory drops the memory frequency from 1333 MHz to 800 MHz Available for X2-2 Full, X2-2 Half, and X2-2 Quarter Racks

17 Exadata Smart Flash Log Accelerate Transaction Response Times using Flash Default (on left) - Choppy response - High Outliers Transaction Response Times Smart Flash Log Enabled Smart Flash Log - 3x faster response - Much lower outliers Automatic and Transparent Uses Flash for Database Logs in a clever way Flash is fast but has slow outliers Erase cycles, wear leveling, etc. Smart Flash Log feature transparently uses Flash as a parallel write cache to disk controller cache Whichever write completes first wins (disk or flash) Better response time and more throughput Uses almost no flash capacity (0.1% of capacity)
