TechEd EMEA 2008 IT Professionals - Introducing Windows Server 2008 R2 Cluster Shared Volumes (CSV) for failover cluster

  • Article

Et voici les notes que j’ai prises durant la session “Introducing Windows Server 2008 R2 Cluster Shared Volumes (CSV) for failover cluster”

Agenda :

  • Configuring R2 Cluster
  • Management
  • Networking
  • HA Workload
  • Hyper-V an d Live migration
  • Cluster Shared Volumes (CSV)

Failover clustering with R2

Drive low cost solution into the entire market

Simplified storage management

Major values proposition :

  • CSV
  • Live Migration
  • Direct Access
  • Branch Cache
  • 64+ Core Support

Windows Server 2008: Failover Cluster Configuration Program (FCCP)

Enhanced Validation

  • Extended Cluster Validate tool
  • Run during configuration and/or after deployment
  • If run on a cluster node, additional tests

Demo : le nouveau Failover Cluster validation Report ==> chouettes schémas pour les dépendances :-)

Migration - upgrade path

  • Built-in migration wizard :
    • 2003 -> 2008 R2
    • 2008 -> 2008 R2
    • 2008 R2 -> 2008 R2
  • Support most networking configuration
  • Migrate by ressource group
  • Pre and post migration wizard
  • Migrate every Workload (role in the Box)
  • All other worloads have their own solution

Migration d'un cluster vers un autre (le nouveau sous R2)
Migration sur le materiel existant (desinstallation d'un noeud, reinstallation en 2008, création d'un nouveau cluster...)

Management

Powershell support :

  • New command line :  en remplacement de cluster.exe (qui est encore là mais on est encouragé à ne pas l'utiliser)
  • Sur Server Core
  • Improve manageability (outil de validation...)
  • Hyper-V and CSV

Demo : Powershell, quelques commandes :
PS:> Get-FailoverCluster -domain nomdudomaine   ==> liste tous les clusters du domaine :-)

PS:>Get-ClusterNode
PS:>Get-ClusterGroup
PS:>Get-ClusterRessource
PS:>Get-ClusterRessourceType
PS:>Get-ClusterNetwork
PS:>Get-ClusterNetworkInterface

Read-Only API
 Reduced privvileges
 improved security
 supported by PowerShell
 
Supportability
 New ETW logging channel
 Performance monitor counters
 
Network Enhancements
 Inter-node communication improvemnent
 Self-healing logic
 Network prioritization for customizability
 
Multi Site enhancements
 Disaster Recovery
 Node in difference subnet
  no more VLANs
 Unlimited distance
 configurable heart beat timeouts

HA New roles

  • DFS-Replication ==> garanti la disponibilité du primary member (autoritative copy).
                         Attention : Replicate to machine NOT in the cluster
  • Remote Desktop (TS) ==> garanti la disponibilité du TS Connection Broker (et donc de la table des sessions TS load balancées)
     
    Hyper-V "Host" Clustering
     combiné avec CSV permet la quick migration et surtout la live migration
     
    2 build-in cluster ressource types :
     Virtual Machine Configuration
     Virtual Machine
     
    Hyper-V Live migration : déplacement d'une machine virtuelle d'un noeud vers l'autre sans downtime.

Cluster Shared Volume

CSV compatibility
 No specail hardware requirement
 Same requirement as standard cluster disk (SAS, Fibre Channel, iSCSI)
 Standard file system : NTFS
 Support Hyper-V Workload

CSV benefits
 Easier Storage management
 Optimized Capacity Plannoing
 Improved performance
  Dynamic I/O redirection
  network prioritizatrion
 Higher availability
  node fault Fault tolerance
  network Fault tolerance
  SAN Fault tolerance
