Customer Concerns and Needs
• Manageability of Infrastructure
– Heterogeneous and Complex
– Operations Monitoring
• Deployment Time
– Reducing Go-To-Market for systems and new applications
• Reliability
– Bullet-Proof Infrastructure and DR
• Capital Expenditures and ROI
– Maximize physical system usage to maximize return
– “Cost vs. Value”
• Implication
– Loss of Revenue

Customer Technical Requirements
• Highly Available Infrastructure
• Disaster Recovery (4 Hours Downtime Max)
• Leverage Solaris Zones
• Portable Data
• No Idle Boxes
• Oracle 10g Support
• Integration with Current HDS SAN Infrastructure
– Shadow Image and TrueCopy (VCS, VxVM)
• Integration with Pre-Existing NBU Infrastructure on AIX
• Minimal Impact to their Operations Support Model
Symantec Vision 2007 8
Infrastructure Considerations
• Solaris 10 on the Sunfire V890 Platform
• Boot from SAN (No internal Disk)
• Zone Root on Shared Storage
• Loop-Back File Systems
• Oracle 10g R2 Installed in each Non-Global Zone
• HDS TagmaStore USP Storage/SAN
• HW Based Replication (TrueCopy)
• NetBackup on Different Platform

Local Clustering and Zone Failover
Primary Site VCS Cluster
• Each Non-Global Zone contains an Oracle environment which can be switched between physical servers in the cluster.
• All data is on the SAN, so the Oracle Zone is live on the server where the storage is active.
• Each Zone is independent of all others.
• To the DBA, Oracle looks like it exists on its own server.
• Oracle benefits from Storage Foundation’s version of ODM.

Backup and Recovery
• Off-Host Backup Using Storage Foundation (VxVM)
– Cross Platform Data Share (CDS Disk Group)
– Shadow Image/CCI vs. Disk Group Split and Join
– Netbackup
• Disaster Recovery v.s. Alternate Data Center
– Leverage All Capital Investments
– Distribute Resource Load (Thresholds)
– ROI Achieved Much Sooner

FireDrill Site Failover Verification
• Currently being Implemented
• Allows for Non-Disruptive Site Failover Testing
• Integrates with TrueCopy® Agents and Shadow Image®
• Compliance and Audits

Realized Benefits and Results
• Reduction in Server Count
• Configuration Complexity Reduced
• Cross Platform/Off-Host Processing
• Reduced Admin Time and Cost
• Tangible ROI (Maximize HW Investments)
• Portable Operational Environments (Dev/Test/Prod)
– “Have Disk Will Replicate”
– Physical Server Moves are Less Complex
– Application Hosting Options
Symantec Vision 2007 19
Deployments Considerations
• Oracle– Binaries Local vs. Shared Storage
– ODM library
• SAN– Bi-Directional Replication
– IP Resources for HORCM Always Active
• Zone Configuration– Ensure Container Name is Defined (VCS Resources)
– Default Routes @ Global Zone Defined
• Dev/Test/Staging– Create a Sandbox
• Reduce Complexity– Cross Platform Tools (VCS, VEA, SF Management Server)
• Documentation– Log all Changes and Updates
