Virtual Recovery for Real Disasters:Virtualization’s Impact on DR PlanningCaddy TanRegional Manager, Asia Pacific OperationsDouble-Take Software

I’m Not Prepared - So What?Business-Critical Applications and DataERP, CRM, Accounting, Sales Force Automation“40% of all companies that experience a major disaster will goout of business if they cannot gain access to their data within 24hours.” (Gartner)E-mail has become the “lifeblood” of businessIntegration with business-critical systems“79% of companies accept email as confirmation of orders,approval, etc.” (Osterman Research)Your systems are your business – it’s not just software;it’s how you run things on a day-to-day basis!

Meeting ComplianceSOXCOOPSEC (NYSE & NASD)SEC (Federal Reserve / Treasury)HIPAAMost regulations do not mandate how data should beprotected, but do have disaster planning requirements andrequire provisions for data backupCompliance is only the catalyst, not the driver –DR/BC solutions should have their own value andshould allow IT to better support the business

The Keys to RecoverabilityRemote Recovery SnapshotRecoverySystem State onData IntegrityEnsured byWrite-Order,TransactionalReplicationMonitoring and Failoverfor Servers andApplicationsEnterprise-Level, CentralizedManagement for DataProtection

A Platform for Recoverability

DR ChallengesCostAdditional hardwareAdditional tools and training Complexity– Management and provisioning– Lock-step hardware and software upgrades Reliability– Complex solutions are hard to test– Requires specialized training for personnel

Virtualization – SolutionsVMware VMotion VMware VMotion HA Microsoft Clustering That’s why we’re all here, right?

Virtualization Strategy - TechnologyProvide the broadest range of software solutionsfor recoverability in virtualized environments. Double-Take for Virtual Systems – Windows guest OS based replication for real-time data protectionand application availability and the highest levels of recoverability Double-Take for VMware Infrastructure– Replication of entire virtual machines (including non-Windows OSbased guests) running on VMware ESX Server for disasterrecovery Hypervisor-based ESX Replication– Real-time, continuous replication of ESX virtual disk files stored onVMware file system (VMFS) volumes for disaster recovery or highavailability

Double-Take for Virtual SystemsSupported in and tested for virtual machineenvironmentsFlexible configuration options:Virtualized source or target – or bothFull Compliment of Double-Take features:High Availability and Disaster RecoveryLAN and WAN SupportOne license of Double-Take for Virtual Systemssupports running on up to 5 virtual machines 7,995 includes 1 year of maintenance

Customer Scenario ACredit Union CustomerCentralized Data Center, Cold Site for Disaster Recovery100 Servers (physical & virtual)Recently migrated from hp to IBM System x & VMwareKey Business Drivers:Failover key applications in under 60 minutesRecover all other applications in 24-48 hours

Customer Scenario ABusiness ContinuityBCP in place, non-IT sponsorTier 1 Unix workloads are continuously replicated (critical business component on IBMSystem p)Remaining 100 server workloads considered Tier 2 & 3Next StepsDefine RTO & RPO for each workload, group into Tiers 2 & 3Completed as a part of several brainstorming sessions with customerEducated customer on product possibilitiesDouble-Take & SRO was chosen as the best fit product to support Tier 2 & 3 workloadsLicensing spanned DT for Windows & DT for Virtual Systems

Customer Scenario AOvercoming ObjectionsWe’ve used Double-Take before, but what about SRO?Double-Take SRO Trials were installed as part of a POC and worked flawlessly the firsttime. The customer was impressed.How do we know how much bandwidth we’re going to need?We generated a report from Tivoli Storage Manager to determine how much incrementaldata was changing on a daily basis. After analyzing the current WAN utilization, we wereable to determine the quantity of data that could potentially move through a DS3. Thedaily incremental changes were far below the daily transfer limit.What else?
