Caution
If you decide to tune your virtual network adapters, it can make performance
worse. It is recommended that any changes to default settings are thoroughly
tested in your environment and only made if they are absolutely necessary to meet
business requirements.
Windows Failover Cluster Network Settings
When you use SQL Server AlwaysOn Failover Cluster Instance or AlwaysOn
Availability Groups in a virtualized environment, adjustments are necessary to the
default failover cluster network settings. AlwaysOn Availability Groups allows you to
continue to use VMware DRS and vMotion without causing unnecessary interruptions or
failovers. In most cases that use AlwaysOn Failover Cluster Instance, vMotion is not
possible because shared RDM devices will be used. However, in cases where direct
in-guest iSCSI access is used for AlwaysOn FCI shared cluster disks, you will be able
to continue to leverage VMware DRS and vMotion, provided the recommended
adjustments are made.
Figure 8.3
displays an example of the Windows Failover Cluster
settings, with the network settings highlighted.
