Configuring your Windows 2008 cluster
The default quorum resource in a Windows 2008 environment will vary depending on
your configuration (number of nodes, shared disks, and so on). The ideal quorum
resource to use for GeoCluster is the Node and File Share Majority. There are other
quorum types available. Review the following table to determine which quorum is
appropriate for your environment.

Type
Description
GeoCluster
Recommendation
Node
Majority
This quorum is recommended for clusters with an odd
number of nodes. The cluster can handle failures of half
of the nodes (rounding up) minus one and still stay
online.
Node
and Disk
Majority
This quorum is recommended for clusters with an even
number of nodes. The cluster can handle failures of half
of the nodes (rounding up), as long as the witness disk
remains online, and still stay online. If the witness disk
fails, the cluster can handle failures of only half of the
nodes (rounding up) minus one and still stay online.
Node
and File
Share
Majority
This quorum is recommended for clusters with special
configurations, such as GeoCluster. The cluster can
handle failures of half of the nodes (rounding up), as
long as the witness share remains online, and still stay
online. If the witness share fails, the cluster can handle
failures of only half of the nodes (rounding up) minus
one and still stay online.
