5 Database Storage Consolidation What s New in Automatic Storage Management Oracle Database 10g Release 2 An Oracle Open World 2005 Presentation

6 Agenda Quick review of Automatic Storage Management (ASM) Next logical step to Database Storage Consolidation Simplified flexible management Enhanced storage capacity utilization Higher performance ASM migration ASMCMD utility Summary ASM core value propositions

7 What Does A in ASM Stand For? A. Awesome storage manager B. Agile volume manager and file system for the database D. Available database storage E. Automatic Storage Management The Answer is: All of the above!

8 ASM is the best thing that has happened to databases since SQL. ASM alone makes 10g worth while. Storage has become a commodity, I only need to present it to 10g and ASM does the rest. Laurence Grant, Dir. of Enterprise Computing Systems Talk America Holdings, Inc.

9 What is Automatic Storage Management A storage manager designed to manage Oracle Database 10g data files offered at no additional cost Volume Manager File System Clustering capabilities Reduce Cost and Complexity Without Compromising Performance or Availability Simplifies and Automates Database storage Management Increases Storage Utilization and Agility Predictably Delivers on Performance & Availability SLA s

10 ASM Features ASM Disk Group LUN LUN Storage Infrastructure LUN 1. Volume Management with 1MB or 128KB striping 2. Database File System with performance of RAW I/O 3. Supports clustering and single instance 4. Dynamic data distribution 5. On-line add/drop disk with minimal data relocation 6. Automatic database file mgt 7. Flexible mirror protection

11 ASM Supports RAC and Single Instance for All Storage Types LAN Oracle DB ASM Oracle DB ASM Oracle DB ASM Storage Area Network ASM provides value for all storage platforms Entry level RAID High end RAID SATA SAS Volumes & RAW Partitions NAS JBOD

12 On-Line Capacity Management Add Drop Resize Disk Group Disk Group Agility to meet demand and changes in workloads

13 Automatic Data Distribution Unstriped Disks Striped Disks Efficient relocation of data during rebalance No more hot spots - eliminate manual I/O tuning Optimal performance

14 No Performance Degradation Over Time Database Never Gets Out of Tune ASM Percentage relative to Baseline (TPS) Non-ASM (Gets out of tune in time) TIME Graphical representation only (not a benchmark)

15 Improves Storage Utilization Before ASM Conventional wisdom Pre-allocate storage Difficult to add/remove and resize storage Leave headroom to grow With ASM Provision storage when you need it and save money Allocate what you need Simple to add or remove when needed Save time and money Ctrl file Redo log Data file 1 ASM Disk Group Ctrl file, redo log, data 1, data n Data file n % utilization

16 Awesome Storage Management Talk America Note the even distribution of data across the storage array

17 Summary ASM Value proposition Significantly reduces management overhead Automates data distribution for optimal performance Dynamic on-line capacity management Flexible mirroring protection

18 Extending Storage Management with Oracle Database 10g Release 2

19 ASM Release 2 New Features Greater Flexibility Consolidate databases into a clustered pool of storage with Oracle 10g & RAC Multiple database & ASM version support Enhanced Manageability Unix-like Command Line interface Disk group rebalance control Space Management Improved Data Migration EM GUI migration using RMAN Full support for FTP and XDB file transfer Enhanced DB file transfer utility

20 Next Logical Step to Database Storage Consolidation "The clustered pool of storage managed by the ASM feature in Oracle Database10g Release 2 presents new key opportunities for Vanderbilt to improve storage utilization and save money through database storage consolidation in a single instance Oracle Database10g as well as Real Application Clusters (RAC) environments" Darryl Boone MIS Director Vanderbilt University

21 Data Consolidation into a Clustered Pool of Storage LAN RAC ASM 10g ASM 10g ASM Shared storage across several databases RAC and Single Instance ERP FIN CRM HR Benefits: ERP Database HR Database CRM Database Simplified and Centralized management Higher storage utilization FIN Database Higher performance ASM Disk Group

22 Simplified and Centralized Management Larger LUN size One Disk Group to manage Fewer LUNs to manage Maximizing data distribution across disks Higher bandwidth Wider even distribution Payroll DB GL DB Consolidated Payroll & GL DB 10x50GB 10x50GB 10x100GB

23 Simplified Flexible Management Independent ASM home Easy upgrade or patching of Oracle DB 10g and ASM Multiple Database and ASM version support

24 Enhanced Management Control for Consolidation Flexible control for data re-balance function Option to wait for re-balance to complete Accurate scripting Option to prevent re-balance to start Space Usage and statistics Required free space to maintain redundancy Disk Off-Line Database compatibility

25 Highest Storage Utilization Consolidated shared storage pool capacity Lower cost of acquisition and TCO ERP Database Ctrl file Redo log Data file 1 Data file n Partitions ERP Database ASM Disk Group CRM Database HR Database HR Database Consolidated ASM Disk Group

27 Empower Consolidation by Enhanced Migration to ASM

28 ASM Migration Utility with EM Grid Control Easy migrate and consolidate Wizard walk-through Create migration and process requests Schedule migration requests Report/monitor status of migration requests Fully recoverable fall-back database to reverse migration On-line and off-line database migration Migrate DB files and recovery area to ASM using RMAN

29 ASM XML DB Virtual Folders Access ASM files as if they were XDB folders HTTP/WebDAV Disk groups appear under /sys/asm FTP Copies files in and out of ASM ftp> cd /sys/asm ftp> put my_db1.f Programmatic API Select * from resource_view where eg Find ASM files created before 21-JUN-2005 select * from resource_view where under_path(res,'/sys/asm') = 1 and extractvalue(res,'/resource/creationdate')<'21-jun-2005'

30 Enhanced Migration Options DBMS_FILE_TRANSFER Utility All combinations of ASM and non-asm file transfers ASM to ASM ASM to O/S file (new) O/S file to ASM (new) O/S file to O/S file

31 Migration Summary Three new ways to simplify ASM migration and moving database files New EM Migration utility New XML DB ftp tool Enhanced DBMS_FILE_TRANSFER utility
