The use of this device by people who don't understand it is very dangerous to your data. You should really consider hiring a firm that can train you on how to use it if not manage it completely for you. You might find that it's better to just give up on this probably older piece of gear and get a new NAS or but a SAM-SD for your storage needs.
Anyone qualified to work on it will demand that it be removed. No amount of training makes that device production ready. Just have someone access the data, copy it off and decommision that junk. Have a storage engineer spend four hours of time assessing the needs and telling you what makes sense to buy in the future.
So much this. I am stuck with two of these things until our vmware platform is completely down.
We have the iSCSI model. Just to reiterate how bad these things are: last Thursday one of the units controller A dropped the flash card. While it was failing over to controller B it locked up. Had to.completely down the platform and reseat all cards and controllers. I know I have good backups, that is the only reason I can somewhat sleep at night, that and all "production" applications are already moved to XenServer.
Take the advice of others, get some chain and make it a boat anchor.
