Challenges of Managing Data Explosion

• What problem are we trying to solve?

– Lack of a single solution for all data– Lack of automation in storage provisioning– Complexity of managing performance–Multi-vendor support logistics and finger

pointing– Reducing Storage Total Cost of Ownership

Oracle Cluster File System-Cloud Edition

• What is it?– Automatic Storage Management (ASM) – ASM Dynamic Volume Manager (ADVM)– ASM Cluster File System (ACFS)– ACFS data services (snapshot, replication tagging, security,

encryption)

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

– License fee required for all non-Oracle database and non-Oracle application files

Oracle Confidential

Oracle Cluster File System-Cloud Edition

• 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 elasticity through online storage provisioning

Oracle Automatic Storage Management Enables Elastic Storage

Alert: Disk space low – Add more storage.

Action: Storage added – rebalancing started.

ASM Dynamic Volume Manager

• New general purpose volume platform– Supports ACFS and 3rd party file systems– Eliminates the need for 3rd party VMgrs

• New ASM volume management service– Cluster and single host volumes– Loadable kernel driver

• ‘Dynamic Volume’ is an ASM file– +DATA/volume1 /dev/asm/volume1-123– Leverages ASM features– Easy on line provisioning

• Cross platform (Linux, Windows, UNIX)• Managed using ASMCMD, EM and SQL

Note: An AVD volume device may not be used as an OS boot or swap device, nor used as a root file system of the OS

ACFS Tagging

• ACFS Tagging allows group operations on files spread throughout your file systems– ACFS Tagging assigns a common naming attribute to a

group of files– File operations can be performed based on tagging attributes

• Tagging is configured and managed by ‘acfsutil tag’ command line– Specify tag names for directories and files

$ /sbin/acfsutil tag set –r resume /dev/asm/acfsvol- 302/test/resumes

Oracle Confidential

ACFS Replication

• Compliments Data Guard and provides a complete DR solution for all files• Enables replication of ACFS file systems across the

network to a remote site• Replication logs are used to replicate from primary to

standby asynchronously

Oracle Confidential

Key Drivers for Data Security & Encryption

– Sarbanes-Oxley (SOX), J-SOX, HIPAA– GLBA– Payment Card Industry (PCI)– EU Privacy Directives, CA SB 1386….– Adequate IT controls, COSO, COBIT– Separation of duty, Proof of compliance,

Risk Assessment and Monitoring

Regulatory Compliance

Oracle Confidential

ACFS Security

• Fine grained access control in addition to OS ACLs• Enforces security policies through realms, rules, rule

sets and command rules – Realm is a group of files/directories secured for access by users– Rule sets are collection of rules– Command rules use rule sets to allow/disallow operations

• Integrated with Oracle system mgt tools– ASMCA support for basic configurations– Extensions to ACFS command line tools for easy use via acfsutil

Oracle Confidential

ACFS Encryption

• Protects data-at-rest through encryption• Prevents unauthorized use of data in case of data loss or theft• Secure encryption ‘keys’ to decode data

• Flexibility to encrypt the entire file system and/or just individual files and directories• Transparent to users and applications– Users and apps get decrypted data

• High level protection using two keys– File Encryption Key (FEK) – to encrypt file data– Volume Encryption Key (VEK) – to encrypt FEK

ACFS Use Cases

• ACFS file systems exported thru NFS/CIFS

• ACFS file systems exported thru NFS/CIFS

• Single node or cluster ACFS file systems

• Single node or cluster ACFS file systems

"Oracle’s new security feature in ACFS gives us fine-grain and secure control over sensitive data

that needs the extra protection. In addition, ACFS replication coupled with Oracle Data Guard

provide a complete Disaster recovery solution for database files, external files and all other general

purpose files in the OS".

Daniel SmithSenior DBA, Carfax Inc.

"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."
