Presentation

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

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!

“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.”

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

ASM Features

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

Improves Storage Utilization

Conventional wisdom

• Pre-allocate storage

• Difficult to add/remove and resize storage

• Leave headroom to grow

Provision storage when you need

it… and save money

Allocate what you need

Simple to add or remove

when needed

Save time and money

Awesome Storage Management Talk America

Note the even distribution of

data across the storage array

Summary – ASM Value proposition

• Significantly reduces management overhead

• Automates data distribution for optimal

performance

• Dynamic on-line capacity management

• Flexible mirroring protection

Extending Storage Management with

Oracle Database 10g Release 2

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

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"

Data Consolidation into a Clustered Pool of Storage

• Shared storage across

several databases

• RAC and Single Instance

• Benefits:

• Simplified and Centralized

management

• Higher storage utilization

• Higher performance

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

Simplified Flexible Management

• Independent ASM home

• Easy upgrade or patching of Oracle DB 10g

and ASM

• Multiple Database and ASM version support

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

Highest Storage Utilization

• Consolidated shared storage pool capacity

• Lower cost of acquisition and TCO

Empower Consolidation by

Enhanced Migration to ASM

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

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'

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

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

Management Flexibility with ASM Command Line Interface (CLI)

• Interactive Unix shell-like CLI for

ASM file administration • ASMCMD> ls

• Non-interactive CLI mode for

scripting and batch processing • ASMCMD ls –lH
