Configuring the Virtual Network 25
Recommendations
• Functional areas with more than one connection must be spread across
adapters to help maintain redundant connectivity in the event of a device
or port failure.
For example, for iSCSI implementations, dual paths to iSCSI targets allow
for the loss of one network port or an adapter if the connections are spread
across different adapters. This distributed iSCSI connection layout,
when used in conjunction with a proper iSCSI initiator and a multi-path
driver configuration, allows the parent partition and VMs to maintain
access to storage resources in the event of a connectivity topology change.
• Proper configuration is required to maintain connectivity in the event of a
limited hardware failure.
To ensure proper iSCSI configuration, see the
Dell Storage Solutions for
Hyper-V
guide available from the Dell Support website at
support.dell.com . The document discusses the proper installation of all
storage-specific drivers (such as the multipath I/O drivers) and support
software. This document also contains information to ensure the correct
external network switch configuration.
• Proper planning is required for the failover clustering environment.
To ensure proper configuration, and for more information on high
availability options available on Hyper-V, see the
