remote access via ssh or something similar (for instance talking to an API with SOAP, XML, ...) is very, very import in any scenario while working with iSCSI and/or FC LUNs AND using storage snapshot and replication capabilities.
We need that remote access for synchronising VMware Snapshots or Application states against the block i/o luns.
Open-E uses some sort of implementation of IPSEC for security for iSCSi and other things. I have not used it, yet. I am thinking of trying to use it instead of the troublesome VPN we are using now.
