One thing interesting about this is the lack of the controller for the FC-AL disksThe controller is an integral part of the V480 system.
I also got a D1000 array with this, so I'm wondering if it was booted from the D1000...?That FE Handbook archive also can show you information for the D1000 array. It is a JBOD array, so booting from it could be a possibility.
Also curious to know why they needed 10 ethernet ports :P.You will have to go ask the previous user/sysadmin. Perhaps it was a web server or an apps server.
