    • Virtualização VMware para Continuidade de Negócios e Recuperação de Desastres Rodrigo Rezende Systems Engineer
    • Agenda
        • Como a VMware Endereça a Continuidade de Negócios
        • Considerações para Disaster Recovery
        • Site Recovery Manager
        • Próximos Passos
    • Definição de Continuidade de Negócios Disaster Recovery Como voltar a normalidade de forma rápida após um desastre? Alta Disponibilidade Como previnir e minimizar o downtime? Proteção de Dados Como gartantir que dados importantes não se percam? Continuidade de Negócios Como manter o negócio rodando
    • Vamos a Norma – BS25999
    • Continuidade de Negócios: Visão Macro
      • Expectativa de Disponibilidade Continua aumentando
        • RTO’s diminuindo de >24 horas para <12 horas
      • Custo do downtime continua Crescendo
        • Aumento da dependendica da infraestrutura x86
      Continuidade de Negócios = Reduzir “Downtime” 2.5 1.0 0.0 $Millions per Hour 1.5 2.0 0.5 Energy Telecom Manufacturing Average Financial Svcs IT Insurance Retail Pharma Source: META Group Custo de Downtime /hora
    • Desafios em Implementar a Continuidade de Negócios
      • Custo
        • Hardware adicional; identico 1:1
        • Ferramentas e Treinamentos Adicionais
      • Complexidade
        • Gerenciamento e Provisionamento
        • Necessidades específicas para cada aplicação
      • Confiabilidde
        • Soluções Complexas são difíceis de testar
        • Exige treinamento específico da equipe

    • Desenvolvendo uma Solução de Continuidade de Negócios
      • Gerenciamento
        • Automatize e Simplifique
      • Dados
        • Proteção total dos Dados
      • Infraestrutura
        • Redução de custos e Complexidade
    • Melhorando a Proteção dos Dados
      • Backup Tradicional
      • Disruptivo para aplicação e usuários
      • Lento, processo complexo para full restore
      • Dependencia de hardware amarra o processo de backup/restore
      • Backup comVMware vSphere
      • Não disruptivo
      • Permite off-host, off-LAN backup com softwares de backup via vStorage APIs for Data Protection
      • Permite babkup em nível de imagem e de arquivos das VMs.

      • Agent-less, disk-based backup and recovery of your VMs
      • VM or file level restore
      • Incremental backups and data de-dupe to save disk space
      • Quick, simple and complete data protection for your VMs
      • Centralized Management through VMware Infrastructure client
      • Cost-effective use of storage for backup data
      1. Backup 2. Restore
      • VM goes down
      • Select VM images/files to recover
      • Restore…VM running in seconds
      • Schedule backups via VC
      • Snapshots taken
      • Data de-duped and stored
      De-duplicated Storage X vCenter Server X vCenter Server
    • VMware Data Recovery Key Components
      • vCenter Server integration
        • vSphere Client Plugin
        • Wizard driven backup and restore job creation
        • Automatically import virtual machine inventory
        • Awareness of HA/VMotion/DRS
        • Leverage vCenter licensing engine
      • VMware vSphere
        • VSS support via VMware Tools
        • Changed block tracking functionality allows backups to be more efficient
      • Destination Storage
        • Any VMFS storage: DAS, NFS, iSCSI or Fibre Channel storage plus CIFS shares as target
        • All backed up virtual machines are stored in a deduplicated datastore
      • Backup and Recovery Appliance
        • Linux appliance in OVF format - leverages vStorage API for Data Protection to discover, manage backup and restore
        • First backup is full VM, then incremental forever
        • VM or file level restore
      VMware vCenter Server
    • Improved Recovery with VMware Data Recovery
        • Backups and restores can run simultaneously

          • Replace a lost VM
          • Restore to a different location/datastore
          • Select disks to restore
        • Fast “roll back”:
          • Use change tracking to roll back a virtual disk/Virtual Machine to an earlier state
          • Only transfers modified blocks for fast restore
        • Restore Rehearsal:
          • Run a restore of a VM to a different datastore and disable networking

        • Site Recovery Manager
        • Próximos Passos
    • Cenarios com Site Recovery Manager Failover to passive DR site Failover to active DR site Bidirectional failover Local failover Recovery Recovery Production Production
      • Most common traditional scenario
      • Very expensive architecture
      • Leverage recovery infrastructure for test, development, training
      • Reduces sunk cost of recovery site
      • Production applications at both sites
      • Each site acts as the recovery site for the other
      • Less common scenario
      • Protection against large localized failures in datacenter
      Production Production Production
    • Topologias
      • Padrão
        • 1:1 mapping between each protected site and its recovery site
      • Shared Recovery Sites:
        • Multiple sites can be protected by a single, shared recovery site
        • Leverage for remote office/branch office topologies
      New in SRM 4.0!

    • Site Recovery Manager Licenciamento
      • License SRM for what you protect
      • No extra licenses required for failback
      • vSphere licenses required for both sites
      • Example 2: Licenses for bi-directional protection
      • 2 vCenter Server instances
      • 6 processors VMware vSphere (4 processors for Site A, 2 for Site B)
      • 6 processors Site Recovery Manager
