Does Windows HPC Server 2008 provide head node failover?
A. Microsoft HPC Pack 2008 supports failover clustering services, included with Windows Server 2008 Enterprise or Datacenter, to provide a second head node for improved cluster availability. However, Windows Failover Clustering is not a feature of Windows Server 2008 HPC Edition. In order to take advantage of failover clustering, appropriate licenses and media of Windows Server 2008 Enterprise, or Datacenter, will need to be acquired and installed for the two cluster head nodes. Additionally, licenses and media for Microsoft SQL Server, Standard or Enterprise, will need to be acquired to utilize the database clustering services necessary to provide resiliency for the system databases used for management and job queuing.
