Why Continuous Availability? 3
The Facts of IT Life 2013 Organizational reliance on information is on an ever- increasing trajectory Users expect 24x7 access One ITs biggest concerns is the availability of information IT is under pressure to reduce spend while increasing service 4
The Evolution of Availability High Availability In-data-center Application Restart Continuous Availability Application continues with no disruption (Zero Downtime) Convergence Traditional Disaster Recovery Tape Backup and Offsite Rotation Advanced Recovery Replication to Second Site 5
Customer Challenges 6
Why Rethink the Traditional Approach to Disaster Recovery? þ Expensive to implement þ Expensive to maintain þ Unreliable During your last major disruption, did you even consider using your DR solution? 7

Service Description 11
Traditional Approach to Disaster Recovery Active/Passive Data Access Traditional industry-standard approach to DR Host/App/Array Replication Information read / write accessible only from one instance at a time Upon failure, data available at second instance (zero RPO) Infrastructure in second instance is typically underutilized Failover and application restart is a manual process LUN 1 P LUN 2 P Instance A Active Failure Domain Array Replication Manual Invocation LUN 1 P LUN 2 P Instance B Passive Failure Domain 12
What is Continuous Availability? Disaster Recovery Active/Recover Draw from Active Feed Eliminate SPOF* via: Backup Site Capability Expression Tier: 1, 2, 3, 4 RPO RTO Examples SRDF/RecoverPoint SRM Service Restoration Minutes > Hours> Days (if at all) High Availability Active/Passive Draw from Active Feed Eliminate SPOF* via: Backup Capability Expression Need + Backup Capability e.g. N+1, N+2, etc. Examples Active/Passive Clustering RAID-5/6 Service Restoration Milliseconds > Minutes (may not be noticed) Continuous Availability Active/Active Draw from ANY Feed Eliminate SPOF* via: Parallelism Capability Expression Parallelism Factor x Need e.g. 2N, 3N, etc. Examples DNS Dual Power VPLEX Mirrors Service Restoration Instantaneous > Microseconds > Milliseconds 13
Four (4) Key Components of Continuous Availability 1. Active/Active Data Center An Active/Active Data Center consists of two or more data centers that can process the same transactions, and each data center has the capability to handle the loss of the other data center 2. Active/Active Applications Applications are architected to run in two or more data centers simultaneously 3. Data Locking Mechanism Mechanism that allows multiple writers to the same data, and protects simultaneous update to the same set of disk sector(s) 4. Data Coherency Mechanism Mechanism that maintains data coherency between sites 14
Traditional DR vs. Continuous Availability Utility company has a power failure at primary Data Center backup DC with Tier-1 standby equipment 40 miles away has power Hospital has a power failure at primary Data Center Continuous Availability Architecture Downtime: 16 hours Downtime: 0 hours Decision Wait until power is restored Reason Too long to fail-over and failback, critical apps have DR, non-critical do not Decision No event, no decision Reason Active/Active environment with load balancing enabled production in both centers if one was down, the processing load automatically migrates to the other 15

Benefits 22
Continuous Availability: Making the Case for the journey Single availability solution + Eliminate downtime for multiple scenarios + Repurpose non-production assets + Eliminate most DR scenarios Potential 28-50% Reduction in Compute Cost 23
Additional Availability Architectural Benefits Converged HA & DR can save CAPEX Fewer servers Less storage (fewer copies of data) for DR testing Converged HA & DR can save OPEX Fewer servers fewer storage admins, less licenses, less labor, less space/power/cooling, less patching Less impact on App, NW, & DB from DR testing Hardware/software refreshes will seldom require an outage (storage, server and infrastructure) Simplified Environment Converged HA & DR uses same solution Enables promise of the cloud App & Data Mobility Better data consistency alignment over traditional point solutions 24
CA Enabled with Converged HA & DR for all environments, including active/passive clustered Failure DR Outage<RTO HA Same Site CA - 2-Site HA Scheduled Events ~85% of Outages Site Maintenance (whole site or component) Software application upgrade/same DB Software application upgrade w/db upgrade Software Agents, BIOS, OS, & Utility Unscheduled Events ~15% of Outages Hardware Component Failures Human Process Error Network Power SAN Failure Site Outage - Recoverable Disaster Events: < 1% of Outages Site Loss Catastrophic (outage > RTO) Very Large Scale Regional Disaster (outage > RTO) 25
The EMC Value Proposition Transform Your Environment to Meet Today s IT Demands Realize the promise of the cloud with both application and data mobility Deliver Always-on Always-available IT Services Enable failure detection and automatic service replacement for technology and site loss Reduce cost of acquisition, hardware maintenance, software maintenance, management and deployment Eliminate idle assets Retire disaster recovery failover and DR practices Simplify your environment: fewer servers to maintain and monitor, faster problem resolution Continuous Availability Made possible with EMC VPLEX & off-the-shelf technologies 26
