Replicate in HA

MACioffi — Mon, 05 Aug 2024 12:26:04 GMT

We are considering setting up HA for Replicate in Windows. I noticed an older doc that has the below recommendation/requirement. Is this still accurate? I sent this to the storage folks and they asked for some clarification. Additionally is there an additional license fee for deploying in an HA configuration?

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.

Storage Team Response:

The backend storage is NFS, but the failover cluster vm uses/sees it as a block device. It sounds like they are saying nfs/smb based data files are not recommended due to latency, not vms using nfs backed storage.

Thank you.

@MACioffi

for VMs, the storage connection configuration for storage. , can be check by your VM admin to see if the share storage for the cluster is set for iSCSI-based
