How does HA iSCSI work?
Posted on 2014-12-02
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.
