Manage Data Growth#1 Priority of Database Users*

* IOUG Storage Survey 2010

• Manage Storage More Efficiently

• Optimize Storage Performance

• Reduce Overall Storage Costs

• Protect Against Data Loss

Cloud computing is a model for enabling convenient, on-demand network access to a shared pool of

configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction.

CloudFS Meets KeyCloud Computing Requirements

• Simplifies pooling of storage across databases, middleware, and applications in a cloud

• Provides network accessible storage with unified namespace for databases and files

• Supports rapid elasticitythrough online storage provisioning

• Multi-tenancy servicing multiple clients with exclusivity

3rd Party FS

ASM Dynamic Volume Manager (ADVM)A General Purpose Volume Manager

• Designed for cluster and single host volumes– Loadable kernel driver

• Supports ACFS and 3rd party file systems– Eliminates the need for 3rd party volume managers

• Leverages ASM features– Dynamic storage provisioning

• Cross platform (Linux, Windows, UNIX)• Easy to managed using ASMCMD, EM and SQL

ADVM

ASMDiskGroup

• Standards based general purpose cluster file system • POSIX, X/OPEN for UNIX/Linux for standard user interface• Windows file system compliant• Ideal for Oracle database, applications and middleware binaries (homes),

administrative files and external BFILEs

• Cache coherent file system with global name space• Supports NFS and CIFS network protocols• Easy to manage cross OS platform

– Linux, Windows, Solaris and AIX– Managed thru native OS interfaces and Oracle system mgt tool

ACFS Read-Write Snapshot

ACFS File System

……………………………….. FS Snapshot

FS Snapshot FS

Snapshot

• Dynamic, fast, space efficient, “point in time”, read-write copies of ACFS file systems

• What problem does it solve• Eliminates expensive 3rd party snapshot solutions• Enable test and development

• Use snapshot copy of production data for test and development

• Recover quickly from online disk snapshot backups and/or inadvertent admin errors

• Offload backups using snapshot image• Up to 63 snapshot images per ASM file system

ACFS Replication• Enables replication of ACFS file systems across the

network to a remote site• What problem does it solve

– Compliments Data Guard and provides a complete Oracle DR solution for all files

– Eliminates the need for 3rd party replication software• Replication logs are used to replicate from primary to

standby asynchronously

Oracle Confidential

ACFS Tagging

• ACFS Tagging assigns a common naming attribute to a group of files

• What problem does it solve– File operations can be performed based on tagging attributes

on files spread throughout multiple file systems

• Example: You can now replicate all files tagged “Oracle Home”– Achieve complete DR solution for Oracle homes and

database file (through Data Guard)

ACFS Security• ACFS Security uses Realms, Rules, RuleSets, and

Command Rules to enforce security– Managed by a ‘Security Administrator’– Modeled after Oracle Data Vault

• Realm is a virtual container of – Users– Files and directories, access defined by security filters– Rules and rule sets defining access– Command rules to allow/disallow operations

• What problem does it solve– Fine grained access control in addition to OS ACLs– Example: Grant operator Joe read only access to MedicalRecords

between 9-11pm for backup purposes.

ACFS Encryption

• Enable users to encrypt data stored on disk– Flexibility to encrypt the entire file system and/or just individual

files and directories– Transparent to users and applications

• What problem does it solve– Protects data-at-rest through encryption

• Prevents unauthorized use of data in case of data loss or theft

• Secure encryption keys to decode data– File Encryption Key (FEK) – to encrypt file data– Volume Encryption Key (VEK) – to encrypt FEK

ACFS Use CasesThe preferred file system for non-database files

• System, Database, Application and Middleware files on ACFS• Shared homes in a cluster configuration• Shared administrative/diagnostic files, log files, staging area files• Oracle database backup sets, archive logs and dumpsets

• Business Data on ACFS• Storing DB external files (large objects) business data stored outside of

DB tablespaces• ACFS configuration alternatives

1. Shared cache coherent cluster file system on all cluster nodes• A better (faster and more reliable) alternative to traditional NFS

Filers 2. NFS/CIFs network file servers

Export NFS/CIFs files to clients on the network

Oracle Cloud Storage Licensing

• Automatic Storage Management (ASM) – Free license

• Oracle Cloud File System (cloudFS)– Licensing

• Free with all editions of the database for storing:– Oracle application binaries, Oracle database homes– Oracle software administrative and diagnostics files

• License fee required for:– All non-Oracle database and application files

<Insert Picture Here>

"Oracle Database 11g Release 2 (11.2.0.2) takes us a step closer to Cloud Computing and Cost Optimization.

The new RAC Quality of Service Management (QoS) coupled with wider platform support for ASM Cluster

File System (ACFS) and RAC One node enable predictable performance and higher availability, both

essential in consolidated environments."
