  1. Uptime All the Time: Datacenter Availability Strategies

  2. Threats to availability DATA CORRUPTION APPLICATION FAILURE COMPONENT FAILURE HUMAN ERROR MAINTENANCE SITE OUTAGE

  3. Achieving appropriate levels of availability remote clustering availability remote replication local clustering data availability backup

  4. Common misperceptions of high availability • It’s expensive • It’s complex • It’s difficult to measure • It’s a different problem than disaster recovery • It’s hard to test

  5. High availability doesn’t have to be expensive Myth: • Hardware redundancy • OS restrictions • Poor utilization Recommendation: Add Clustering, Not Hardware • Any platform • Optimal server utilization

  6. Recommended Approach Utilization: “With VERITAS, we're up all the time. We've seen instant results and tangible cost savings, for a 24 month ROI of about $3.4 million.” Joe Wagner, CTO, El Camino Hospital/Eclipsys Outsourcing Increase value of current hardware investment Traditional Approach Utilization:

  7. “We were amazed. We had VERITAS Cluster Server out of the box and failing over applications in less than 90 minutes." IT Director, Financial Company High availability doesn’t have to be complex Myth: • Costly installation • Uncertainty of configuration • Labor intensive management • 5 platforms  5 Solutions Recommendation: VERITAS Cluster Server • Cost effective installation • Cluster simulator • Simple management • 5 Platforms  1 Solution

  8. Availability can be measured Myth: • Unmeasurable SLAs • No historical reports • Unclear of problems Recommendation: Use integrated reporting tool • Track availability • Report Results • Identify problems

  9. Disaster recovery can be one click away Myth: • It’s too expensive. • What about the application? • Unachievable. Recommendation: Protect the data and application • Integrated technology • Automate the recovery steps

  10. HA STANDARDIZATION HA/DR ARCHITECTURE REPLICATION VERITAS EMC IBM NetApp HDS/HP Oracle APPLICATION/ DATABASE SOLUTIONS Datacenter Availability – Solutions

  11. Hardware Investment “Cost was another key consideration because unlike its competition, VERITAS Volume Replicator does not require additional hardware to operate, dramatically lowering the overall cost of ownership” VERITAS $35K $50K TraditionalApproach $150K IT Director, Banco Santander International Replication can be bulletproof and cost effective Traditional Approach: • It’s Expensive • It’s Proprietary • Can’t go the distance Recommendation: Replicate the Volume Bulletproof Replication Over… • Any hardware • Any network • Any distance

  12. Availability can be easily tested Myth: • Risk of downtime • Inconvenient/time consuming • Blind faith Recommendation: Run Firedrills • No production impact • Anytime • Sure Knowledge
