Failover Clustering & Hyper-V for Availability Base para Private Cloud Mobilidade da VM Aumento da Disponibilidade da VM Detecção da saúde do Hardware Detecção da saúde do SO Detecção da saúde da VM Detecção da saúde da Aplicação/Serviço Recuperação Automática Flexibilidade de Implantação

Host vs. Guest Clustering Host Clustering Guest Clustering Serviço de Cluster é executado no host (computador físico) e gerencia as VMs VMs move entre os nós do Cluster Serviço de Cluster é executado dentro da VM Aplicativos e Serviços dentro da VM são gerenciados pelo Cluster Aplicação move entre as VMs do Cluster Cluster Cluster SAN iSCSI

O que o Host Clustering oferece Evita um ponto único de falha “Não ponha todos os ovos em uma única cesta” Host Crashes VMs reinicia em outro nós Restart VM Crashes VM OS reinicia no mesmo nó Recupera VM travada Zero Downtime Maintenance & Patching Live migrate VMs para outros hosts Mobilidade e Distribuição de Carga Live migrate VMs para servidores diferentes para balancear a carga

O que o Host Clustering oferece Aplicação ou Serviço com falhas dentro da VM são movidos para outra VM Application Health Monitoring Aplicação ou Serviço são movidos para outra VM para manutenção ou atualização do SO Application Mobility Cluster iSCSI

Guest vs. Host: Health Detection Fault Host Cluster Guest Cluster Host Hardware Failure Parent Partition Failure VM Failure Guest OS Failure Application Failure

Host vs. Guest Clustering Host Clustering Move VM entre servidores Zero downtime para mover uma VM Funciona com qualquer aplicação ou guest OS Guest Clustering Apps move de uma VM para outra Downtime quando move aplicações Requires “cluster aware” applications running on Windows Server Requer o dobro de recursos – 2 VMs para única carga de trabalho

Combinando Host & Guest Clustering O melhor dos dois mundos para proteção de flexibilidade Alta disponibilidade da VM & mobilidade entre os nós físicos Alta disponibilidade da Aplicação e Serviço & mobilidade entre as VMs Cluster-on-a-cluster aumenta a complexidade Guest Cluster CLUSTER CLUSTER iSCSI SAN SAN

Combinando Físico e Virtual no mesmo cluster Combinação do físico com o virtual é suportado Requer iSCSI storage iSCSI

Planejando a carga em um Guest Cluster SQL Host e guest clustering suportado no SQL 2005 e 2008 Suporta guest live e quick migration Support policy: http://support.microsoft.com/?id=956893 File Server Totalmente Suportado Live migration para mover file server para ambientes diferentes sem quebrar a conexão TCP do cliente Outros Produtos: http://support.microsoft.com/kb/957006

Live Migration - Initiate Migration Client accessing VM Live Migrate this VM to another physical machine SAN IT Inicia o Live Migration VHD

Live Migration - Memory Copy: Full Copy Memory content is copied to new server VM pre-staged SAN Primeiro copia todo o conteúdo da memória VHD

Live Migration - Memory Copy: Dirty Pages Client continues accessing VM Pages are being dirtied SAN Cliente continua acessando a VM, o que vai gerar novas mudanças na memória VHD

Live Migration - Memory Copy: Incremental Recopy of changes Smaller set of changes SAN Hyper-V procura por mudanças e copia de forma incremental Cópias cada vez mais rápidas porque são menores VHD

Live Migration - Final Transition Partition State copied VM Paused SAN A janela TCP é muito pequena VHD

Live Migration - Post-Transition: Clean-up Client directed to new host Old VM deleted once migration is verified successful SAN Atualização das tabelas de roteamento (ARP) Como a session state é mantida não é necessária a reconexão VHD

Escolhendo o SO Hyper-V, 16 node Failover Clustering, e CSV No guest OS licenses 4 guest OS licenses Unlimited guest licenses Hyper-V Server Windows Server Enterprise Windows Server Datacenter Host OS is Free Licensed per Server Licensed per CPU Hyper-V, 16 node Failover Clustering, e CSV

Planejando o Hardware do Servidor Processador compatível com Live Migration Processador precisa ser do mesmo fabricante em todos os nós Não pode misturar Intel e AMD no mesmo cluster Virtual Machine Migration Test Wizard verifica a compatibilidade http://archive.msdn.microsoft.com/VMMTestWizard ‘Processor Compatibility Mode’ pode ser usado quando os processadores forem diferentes (todos Intel ou todos AMD)

Planejando a Configuração de Rede Minimo 2 placas de rede: Internal & Live Migration Public & VM Guest Management Solução Ideal Public network for client access to VMs Internal network for intra-cluster communication & CSV Hyper-V: Live Migration Hyper-V: VM Guest Management Storage: iSCSI SAN network

Guest vs. Host: Planejamento do Storage Host Cluster Guest Cluster Fibre Channel (FC) Serial Attached SCSI (SAS) Fibre Channel over Ethernet (FCoE) iSCSI

Cluster Shared Volumes (CSV) Permite o acesso simultaneo a um volume NTFS Simplifies storage management SAN

Planejando o número de VMs por CSV 4/2/2017 6:36 AM Não há um número máximo restringindo o acesso a um volume CSV Considerar a Performace do Storage Alto número de servers, 1 LUN Verificar a especificação com o fabricante Quantos IOPS seu storage suporta ?

Planejando o Active Directory Todos os nós precisam ser membros do domínio Nós precisam estar no mesmo domínio Precisa de um writable DC acessível Não virtualize todos os DCs DC é necessário para autenticar e iniciar o serviço de cluster Manter pelo menos 1 DC em máquina física

Habilitando VM Health Monitoring Habilitando VM heartbeat Requires Integration Components (ICs) installed in VM Health check for VM OS from host User-Mode Hangs System Crashes CLUSTER SAN
