Hi Cluster Fans, A few weeks ago I posted a blog about configuring IP Addresses with multiple subnets and got some feedback about some additional scenarios to consider. This blog post will discuss the best practice of setting possible owners for the IP Addresses. Setting Possible Owners The...

Hi Cluster Fans, At TechEd Berlin, several customers asked about the complexity of configuring multiple IP Addresses for clusters which have nodes in different subnets, so this short guide will provide a walk-through showing how easy it is to configure using Windows Server 2008 R2 Failover Clustering...

Hi Cluster Fans, A common mistake when creating clustered file is not opening the appropriate firewall setting, Remote Volume Management . This can cause the file server to give errors for various operations. Remote Volume Management provides remote software and hardware disk volume management...

Hi Cluster Fans, In Windows Server 2008 and Windows Server 2008 R2 we have simplified how easy it is to create and use a Failover Cluster. For example, if we detect you are using DHCP in your datacenter, we will automatically assign the cluster as well as clustered applications and services...

Failover clusters ensure that workloads such as File Server, Exchange, SQL, and Virtual Machines are highly available. These resources are considered highly available if the nodes that host resources are up, however the cluster generally requires more than half the nodes to be running, which is known...

Hi Cluster Fans, Over the next few weeks the cluster team is offering a series of public TechNet webcasts focusing on Failover Clustering in Windows Server 2008 R2.

Hi Cluster Fans, Many of you use Failover Clustering to prov ide high-availability to your print servers to ensure that the print spooler resource stays up and running. We have recently released a Rollup Hotfix specific to print clustering which contains several fixes to improve the stability of...

Hi Clustering PowerShell Scripters, One of the things we’ve provided in Failover Clustering PowerShell is a set of CMDlets to easily create highly available workloads in a cluster. PS C:\Windows\system32> Get-Command -Module FailoverClusters | ?{ $_.Name -like "Add-Cluster*Role" } CommandType...

Since Failover Clustering traditionally requires shared storage (you could also use hardware or software replication between nodes), we get a lot of questions about which shared storage types we support. Windows Server Failover Clustering has a very flexible storage model that allows a wide variety of...

With Cluster Shared Volumes (CSV) one of the nodes in the cluster is responsible for synchronization of access to files on a shared volume. This is the node which currently owns the cluster ‘Physical Disk’ resource associated with that LUN, which is referred to as the Coordinator node. Each...
