Windows Server 2008 Failover Clusters: Networking (Part 1)

Configure Heartbeat and DNS Settings in a Multi-Site Failover Cluster

Appendix A - Cluster.exe Commands

1. Adjust the default heartbeat settings by the following commands:

cluster /cluster:<cluster name> /prop SameSubnetDelay=2000 (The default value is 1000 milliseconds, we could set it to 2000 milliseconds.)

cluster /cluster:<cluster name> /prop SameSubnetThreshold=10 (The default value is 5, we could set it to 10.)

 

2. Disable SNP (according to KB http://support.microsoft.com/kb/951037>)

Disable Chimney

netsh int tcp set global chimney=disabled

Disable RSS:

netsh int tcp set global rss=disabled

Disable NetDMA:

Set the following regsitry value to 0:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\EnableTCPA

After that, please reboot both nodes to make the change effective.

3. Pease disable “Receive Side Scaling” on advanced tab of network adapter.

4. Please update KB 983528 to update TCPIP.SYS.

983528 The TCP receive window autotuning feature does not work correctly in Windows Server 2008 R2 or in Windows 7
