yes, ports on the SP are for block only - I.e. Clariion ISCSI  you could also inquire with sales about changing your current 4x1GBit data mover with one that has 2x 10GBit and 2x 1GBit
Is it possible to add additional Gigabit Ethernet ports to a Celerra NS122?  Currently, each of my Data Movers have 4 - 1 gb ports.  I see the Storage Processor has some available slots and I was wondering if a 4-port module is available for expansion or if this is supported.  Thanks.....
