Easy Notable Differences in 2008 SQL Cluster



  • Up to 8 nodes in SQL Server 2005, 16 nodes in SQL Server 2008.
  • No remote execution on the cluster nodes. We can now upgrade or patch a cluster with minimal downtime. Updates and service packs must be apply on each node separately; setup must be executed on each node. The same to add a new node, setup must be executed on each node.
  • Service packs can now be uninstalled.
  • SQL Server 2008 are not supported on WOW mode.
  • MSDTC was required as a cluster resource to install SQL Server 2000 and SQL Server 2005 clusters. SQL Server 2008 does not have that requirement anymore to install a cluster.
