1 Disaster Recovery 101 Sudarshan Ranganath & Matthew Phillips Ellucian

2 SESSION OBJECTIVES Business continuity is critical to every institution and its IT organization. How do you set up your ERP and other Tier 1 apps to reduce the risk of a disaster, and quickly recover from one should disaster strike? Learn about the infrastructure and practices that Ellucian s Cloud Services uses to minimize the impact of a disaster for your Banner systems.

3 AGENDA Tier -1 Apps Disaster Prevention Disaster Readiness DR Execution DR Options 3

4 TIER 1 APPS FOR DISASTER RECOVERY / BC Communication SIS/ERP LMS CRM Other Financial/Operational 4

5 Severity RISKS THAT COULD IMPACT YOUR OPERATIONS Causes Natural disasters Human errors Technological failures Probability Frequent Likely Occassional Seldom Unlikely Catastrophic Critical Demand Surge Staff Attrition Security Breach Power Outage Hurricane /Flooding Hit by Tornado Moderate Negligible CPU Failure Disk Failure/ Trip over a wire Impact Business Interruption Financial Legal Reputational Priority Extremely High High Moderate Low

6 KEY KPIS YOU CARE ABOUT AS AN IT ORGANIZATION Downtime Performance Security Scalability Disaster Recoverability Backup Currency Software Currency Stakeholder Support Costs/Investment Efficiency Application Availability User Experience for Public and Private apps Number of Security Incidents Extent of compromise per Incident Ability of current infrastructure to handle load Time to add capacity in response to demand spike Probability of a disaster affecting the datacenter Time to recover from a site-level disaster Lost work product because of inefficient backup practices, and aging of backed-up data as a result Time to update to newest version after being made available by vendor Effectiveness in furthering student/staff satisfaction TCO to operate solution, ROI for every $$ invested

7 DISASTER PREVENTION Power Facility Network Hardware Application Architecture Replication Process 7

8 DISASTER PREVENTION - POWER Multiple Utilities or Stations A and B power Grids All components connected A&B UPS Generator Generator Backup Fueling agreements for outage >2 days 8

9 DISASTER PREVENTION - FACILITY Multiple Physical Entries for Power, Network Hardened Walls and Roof Temperature Humidity Secure personnel and equipment Entries Multi-stage Fire Detection 9

10 DISASTER PREVENTION - NETWORK Multiple Internet connections Multiple ISP providers Redundant firewalls Redundant core network Servers, storage redundant connections 10

11 DISASTER PREVENTION - HARDWARE Redundancy is key at every level SAN vs. non-san Virtualization vs. Dedicated Server Hardware Redundant cold/warm/hot hardware in DR location

12 DISASTER PREVENTION - APPLICATION ARCHITECTURE Again redundancy is key at every level DB tier and App tier Monitoring & alerting considerations Integrations Customization and Modifications Licensing

13 DISASTER PREVENTION - APPLICATION ARCHITECTURE Backup architecture considerations OS is static Application tier is static Database backup considerations Database backup architecture Fullexp, RMAN, cold, custom hot Archive vs no-archive mode (prod vs non-prod) Data-Domain style vs Tape architecture Architecture must consider RTO and RPO

14 DISASTER RECOVERY REPLICATION Backup Process Replication Process Recovery Point Recovery Time 14

15 DISASTER PREVENTION - PROCESS ITIL Change Management Incident Management Shutdown / Startup Processes Access Control / Role Based Security Training 15

16 DISASTER READINESS How do you test your readiness for disaster Failover Test Power Network test VM test Application / Database test Monitoring test

17 EXECUTION WHEN YOU HAVE A SITE LEVEL DISASTER Requires People & Process Facility to restore Infrastructure (Network, servers, storage, Recovery software, DNS) Most Recent Backups Prioritization Move IP networking from primary to DR Recover Virtual Machines Recover Databases Recover Apps Integrations to other systems 17

18 DISASTER RECOVERY STRATEGIES Strategy RPO RTO Cost Server Replication Secs Min < Hr $$$$$ SAN Replication Min hours Hours Day $$$$ VM + DB logs Hours day Hours - days $$$ Offsite Tape + DR Contract Days Days-weeks $$ Offsite Tape Days Months $ 18

19 SUMMARY DR is about Planning & Testing Readiness Prevention, Readiness, Execution
