1 2012 Symantec Vision Everything You Need To Know About Oracle & Storage Foundation HA MITIGATE IT RISK WITH STORAGE FOUNDATION HA TO AVOID DOWNTIME AND ACCELERATE SERVICE RECOVERY Chris Atkinson Regional Product Manager - EMEA 1

2 2012 Symantec Vision Agenda IT Risk Management Strategies Solution Overviews Mitigating Risk 2 2

3 Understand SOURCES Of Risk & AGGREVATING Factors Human Error Change Processes Component Failure Environmental influence Poor Visibility Complexity Stress Location 60% of all unplanned downtime is caused by human error - IDC 95% of Environmental Disasters are Localized - Gartner Over 78% of companies do not test their DR plans - Gartner 3

4 ITRM Strategies Avoid Increase Infrastructure Visibility Adopt Common Tooling Standards Maintain Service Agility Intelligent Automated Operations 4

5 ITRM Strategies Mitigate MINIMISE Operational & Incident Impact Comprehensive Fault Detection Provide Redundancy Accelerate Full Service Recovery Provide PIT Recovery Mechanisms 5

6 ITRM Strategies Iterative CONTINUAL Process Improvement Pro-Actively Test & Analyse Organisational Learning Process Improvement 6

7 Overview Architecture Basics Oracle HA Architectures Oracle Fundamentals Symantec HA Architectures 7

8 Oracle HA Stacks 11gR2 Cache Fusion Low latency I/O & Fusion Flash I/O Cache Database Single Instance FAILOVER Failover: 5-20 Minutes + Simple App Design Simple Architecture Passive Licenses Saving Linear scale Database Parallel RAC Failover: 10 Seconds + Application Redesign Complex Architecture x2 Licence Cost Scale Overheads EXADATA Failover: 10 Seconds + RAC Configuration HCC ROI DW Specific Niche +XXX Cost Optimised storage 8

9 Understanding DB Recovery Instance Failure DOES result in an outage Redo Log MUST be applied Uncommitted transactions are rolled back Outage Time = Redo Log Delay CLIENT FAN Why Application Redesign For Recovery FAN Notifies status changes TAF/FCF Creates new connections Client MUST use Oracle Libraries FCF/TAF I/O Cache I/O Cache Shared Storage Redo Log Database Redo Log 9

12 Mitigate Reduce Incident Impact Provide Redundancy Comprehensive Fault Detection Accelerate Full Service Recovery Provide PIT Recovery Mechanisms 12

13 SAN Redundancy Impact Of Storage Node Outage Capacity degradation Entire service interrupted Uncommitted require resubmit Instance failure Application Outage/Service Capacity Lost (RAC) Storage Failure (e.g. LUN mapping, path fail) Redo log application ASM DB.dbf 13

14 SAN Redundancy Symantec I/O Shipping Technologies No Service interruption Minimises service capacity loss Interrupted writes captured Application Network I/O Shipping Allows processing to continue Storage Failure (e.g. LUN mapping, path fail) Avoids redo log replay DB.dbf Veritas Cluster File System 14 14
