Storage Foundation supports a Microsoft Failover Clustering configuration.

Microsoft Failover Clustering provides a set of standard resources, such as physical disks, file and print shares, and network addresses and names. Each resource is accessed using a resource DLL and an extension DLL. The resource DLL provides communication between Microsoft Failover Clustering and the resource. The extension DLL allows the user to set the resource properties.

Microsoft also allows vendors to integrate product-specific resources into Microsoft Failover Clustering through the use of custom resource and extension DLLs. SFW's product-specific resource is the Storage Foundation disk group resource with its two DLLs, Disk Group resource DLL and Cluster Administrator extension DLL.

The block diagram below shows the relationship between Storage Foundation cluster components and the Microsoft Cluster Service.

To work in a Microsoft failover cluster environment, you must enable this feature while installing InfoScale Storage.

This installs the Storage Foundation disk group resource DLL and the Cluster Administrator extension DLL.
