Designing for High Availability 25
NOTE: These network types are defined by the Windows Failover Clustering
feature in Windows Server 2008 and are not related to the Hyper-V network types
that are defined in the Dell Networking Solutions Guide for Microsoft Hyper-V.
In a recommended configuration, every node of a typical Hyper-V Host
Cluster should have dedicated network ports for the following:
NOTE: Even though Failover Cluster in Windows Server 2008 does not require a
dedicated cluster private network because it can use the public network to monitor
cluster heartbeat, Dell recommends a dedicated cluster private to ensure the
reliability of the Hyper-V Host Cluster configuration.
Table 3-4. Dedicated Network Ports for Hyper-V Host Cluster Nodes
Network Types Description, Configuration, and Best Practices
Network for
Cluster Private
• One Gigabit (or Fast Ethernet) Ethernet network port for
hosting the Cluster Private network.
• This network is dedicated for use by the cluster service to check
the health state of each cluster node.
• Should be of cluster use type
Internal.
Network for
Cluster Public and
for Parent Partition
Management
• One Gigabit Ethernet network port for hosting the Cluster
Public network and for network access to the Windows
Server 2008 parent partition.
• This network will be used to:
– Manage the Hyper-V Host Cluster using the Failover
Management console
– Manage the Parent Partition and the Hyper-V Role
• Should be of cluster use type
Enabled.
Network for
Virtual Machines
• One or more Gigabit Ethernet network ports to host virtual
machine networks.
• Should be of cluster use type
Disabled to ensure isolation of the
virtual machine network traffic.
Network for
Storage
• Two or more Gigabit Ethernet network ports to host iSCSI
storage network (for iSCSI-based configurations).
• Should be of cluster use type
Disabled to ensure isolation of the
storage network traffic.
