How to failover storage pool between 2 NAS

English

I have 2x QNAP NAS (TVS-h674 QuTS and TS-673A QTS). They have identical storage. They both have 2 storage pools. I want TVS-h674 to be the primary/hot device and TS-673A to be the secondary/cold device. Primary device storage pool 2 contains 1 block-based thick LUN called “UserFolders” with an iSCSI target that is mapped to a Microsoft Cluster consisting of 3 (server) nodes. I want to configure both NAS so that if one is down (e.g. firmware update) the other hosts the UserFolders cluster role.

This must be a common requirement for QNAP users. I can’t find out how to do this. Can someone please point me at the guide that enables me to have hot/cold failover replication, please?

You need two identical (model and OS, not the case for you) NAS and then you can use the new HA feature

If you get a second TVS-h674 you should be able to do it

Doesn’t anyone at QNAP think that the requirement of 2x identical NAS is a limiting and unappealing situation? Surely, enabling a storage pool on one NAS to replicate onto another, dissimilar, NAS is just a basic requirement? I can do this on Azure. I can do this using Mirror Storage Spaces on Microsoft Server. I’d be very, very disappointed if I really can’t do this with dissimilar QNAP hardware. Is this really the situation?

There’s a recent QNAP blog post I found quite-interesting detailing how-to-do this between 2 x QuTS Hero NAS: Failover in 90 Seconds to Maintain Service: Hands-on with QNAP High Availability | QNAP Blog
