Setting up Qlik Replicate in a cluster environment

This section describes how to set up Qlik Replicate in Windows and Linux clustering environments.

Warning note

When building failover cluster solutions with Replicate 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 Replicate 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.
