How does HA iSCSI work?

I have been setting up a test environment with Starwind SAN software and trying to figure out how the high availability would work if one of the storage servers fails.

In the test environment there are 2 windows 2012 servers with the starwind san software loaded.  I can setup the iscsi targets on the san and also set them up as high availability with a partner pointing to the other 2012 server.   In the test environment I have a vmware server that is accessing the iscsi targets on the 2 physical servers.   I have one vm setup on the vmware host with the disk pointing to one of the iscsi datastores.

My question is if one of the starwind servers fails, how does vmware or starwind adjust with this to make the vm not lose the disk ?   It seems like I am missing something with how this process would work.

Thanks.

Basically, you've got a single or many iSCSI Targets, and the storage is mirrored between servers on the back-end.

So the vmware server will always see the same iSCSI IQN and the starwind software would handle that?   When you create the HA within Starwind it will create an IQN and then have a different IQN for the "partner" image.

Correct, VMware vSphere does not have to do anything, it connects to the same IP Address.

all the HA is handled in the background using the Starwind software.

It's the same with many "Clustered" Mirrored/Storage solutions.
