iSCSI failover virtual disk

Post by codac » Mon Mar 12, 2018 3:24 pm

Hey guys,

I do have two QNAP TS-453A with 4 x 2TB harddrives.
What I try to do is to set up a failover iSCSI virtual disk system for our VMWare machine running on a HP ProLiant DL380 Gen10.

So I would need to set up one QNAP TS-453A as the master virtual iSCSI drive and the second one as a slave or backup virtual iSCSI drive.
As soon as the master goes offline, the slave will take over automatically.

I have searched the web but unfortunately there is not much to find.

Could you provide me with hints, tutorials or anything that might help?

Thanks in advance.

This is not something provided free or native to Qnap's OS.
Also their replication service is not real-time enough to support such configurations.
You need to look at host based third-party software for failover, and that also depends on what hypervisor/VMs you're using.
