How to configure heartbeat in windows 2008 cluster

Each Network adapter is in a separate vlan. I have also set the following adapter order. Click Install. Installation is successful, click Close. Click on Validate a Configuration and the wizard will begin. I will enter in the name sql1 and click Add, then enter in the name sql2 and click Add. Select Run all tests and click Next. A summary of your servers that will be tested. Click Next. The test has completed successfully. If you've already registered, sign in. Otherwise, register and sign in.

Video Hub Azure. Microsoft Business. Microsoft Product Support Services does not support the configuration of a cluster with nodes connected by only one network.

At least two of the cluster networks must be configured to support heartbeat communication between the cluster nodes to avoid a single point of failure. To do so, configure the roles of these networks as either "Internal Cluster Communications Only" or "All Communications" for the Cluster service. Typically, one of these networks is a private interconnect dedicated to internal cluster communication. Additionally, each cluster network must fail independently of all other cluster networks.

This means that two cluster networks must not have a component in common that can cause both to fail simultaneously. For example, the use of a multiport network adapter to attach a node to two cluster networks would not satisfy this requirement in most cases because the ports are not independent. To eliminate possible communication issues, remove all unnecessary network traffic from the network adapter that is set to Internal Cluster communications only this adapter is also known as the heartbeat or private network adapter.

The process described in this article:. The information in this article does not apply to Windows Server or Windows Server R2 failover clusters. The scenario where the settings in this article are likely to cause adverse behavior on Windows Server or Windows Server R2, is with a CSV environment.

In the Connections box, make sure that your bindings are in the following order, and then click OK :. Right-click the network connection for your heartbeat adapter, and then click Properties. You may want to rename this connection for simplicity for example, rename it to "Private". If the server is using a MNS quorum, you must have at least one network that has file-sharing capabilities for the MNS quorum to function. We strongly recommend that you have multiple networks on the cluster that have file sharing enabled to avoid a single point of failure for the quorum resource.

If you have a network adapter that can transmit at multiple speeds, and the adapter can specify a speed and duplex mode, manually specify a speed and duplex mode.

This maintains cluster communication over the public network, as a low priority, until the private heartbeat links can be restored.

Important Notice Network Routers are not supported for a private heartbeat network, nor are any other "Layer 3 aware" devices. Third party NIC teaming for Windows , and earlier, is not supported for the private network heartbeat links.

NIC teaming can only be implemented on the public network adapters. Note: This does not mean that NIC teaming cannot be configured successfully within a clustered environment for heartbeat communication. We do not test, document, support or assist in the configuration of NIC teaming for heartbeat communication.

Should an issue arise from attempts to use NIC teaming for heartbeat communication on the private network, we recommend disabling NIC teaming and attempting to configure the private network links using a individual NICs.
