CX4 and VNX only support the multimode SFP and only the approved parts from EMC - these are tested to ensure compatibiliyt.  glen
Dear, We want to know whether we can use an pair of single mode SFP to replace the multimode SFP on CX4/VNX I/O SLIC? Because wo put the SAN switch a little far from the storage.
Can we use single mode SFP on CX4 or VNX?
