  3. Table of Contents • Storage management challenges • Oracle Cluster File System – Cloud Edition • ASM and ACFS overview • ACFS new features in 11.2.0.2 patch set • ACFS use cases • ASM as an integrated solution • ASM reference customers Oracle Confidential

  4. 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 Confidential

  5. 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

  6. 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 elasticitythrough online storage provisioning Applications Enterprise Manager Middleware Database Oracle Cluster File System—Cloud Edition Oracle VM (optional)

  10. ASM Dynamic Volume Manager OS • 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 /dev/asm/volume1-123 ASM DG +DATA/volume1 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 Oracle Confidential

  11. What is ASM Cluster File System (ACFS) • General purpose file system for non-DB files • Journaling, extent based • POSIX, X/OPEN file system solution for UNIX/Linux • Windows file system solution for Windows platforms • Single node and cluster • Scalable and high performance • Supports NFS and CIFS protocols • Multi OS platform - Linux, Windows, Solaris and AIX • Integrated with Oracle system mgt tools • Oracle installation/configuration, EM and native OS tools • Supports advanced data services • Snapshot, Replication, Tagging, Security and Encryption Oracle Confidential

  12. What’s New in Oracle ASM 11g 11.2.0.2 - Patch Set 1 Oracle Confidential

  13. 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/acfsutiltag set –r resume /dev/asm/acfsvol- 302/test/resumes Oracle Confidential

  14. 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

  15. 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

  16. 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

  17. ACFS Encryption Oracle Confidential • 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

  18. ACFS Use Cases Data Type Data Model • 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 • Personal files • Home directories, documents, etc... • System and application files • System files • Application binaries • Business data • Business files not stored in the database • Business critical data ACFS ACFS ACFS

  19. Store Personal Files on ACFS • Configure ACFS as a Network File Server • Single node or cluster for HA • Easy provisioning • Simple management • Client computers can mount ACFS NFS/CIFS file systems • Home directories, documents, photos and personal data NFS or CIFS Network Protocols ACFS FS mount points ACFS Network File Server (NFS/CIFS)

  20. System & Application Files on ACFS SAP Application Binaries Oracle DB Binaries • ACFS configuration alternatives • ACFS single node or cluster server • ACFS Network File Server • Data types on ACFS • System files (not including boot FS and Grid Infrastructure home) • System files, trace files, log files, import/export files, system and application dump files, etc • Application files and binaries • Oracle database home (Shared or node-local) • Oracle and 3rd party application binaries and supporting files I.e. SAP, Siebel, PeopleSoft, etc Siebel Application Binaries Oracle EBusiness Suite 3rd Party File System ACFS File Systems ASM Disk Group

Business Data on ACFS Photos Images BFILEs • Database external files may be stored in an ACFS cluster • Data types • Files or data managed by business applications not stored in database • Images, manuals, reports, contracts, external tables, and BFILEs • Business critical data • Application data with true cluster file system functionality requirements (cache coherency, shared read/write, etc) Medical Images External tables Reports ACFS File Systems ASM Disk Group

  22. <Insert Picture Here> Daniel Smith Senior DBA, Carfax Inc. "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".

  23. <Insert Picture Here> NTT Data Interlink "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."
