Setting up Compose on a Windows HA cluster

This topic describes how to set up Compose in a Windows Server High Availability Cluster environment. For instructions on how to set up a Windows clustering environment, refer to the Microsoft Help.

Warning note

When building failover cluster solutions with Compose using Windows Server Failover Cluster (WSFC) or a Linux failover cluster software, Qlik recommends using a block device (physical, virtual or iSCSI-based) for the shared Compose DATA folder. Using NFS or SMB-based storage is not supported due to the associated latency which could greatly degrade the data transfer performance, as well as due to reduced reliability and compatibility issues. When building a cloud-based high availability solution that needs to span different availability zones, it is recommended to use a Storage-as-a-Service solution that can handle the block-level replication of the storage and that is integrated with the chosen failover clustering software.
