◦ If you have dual-protocol SFPs, you can continue using them after you convert the protocol.
The dual-protocol SFPs do not support 1 Gb iSCSI. If you are converting

host ports to iSCSI, be aware that the dual-protocol SFPs support only a
10 Gb link to the connected port.
◦ If you have 16 Gbps SFPs, and you are converting host ports to iSCSI, you must remove
the SFPs and replace them with dual-protocol or 10 Gbps SFPs after converting the
protocol. As needed, you can also use 10 Gbps iSCSI copper by using a special Twin-Ax
cable with SFPs.

8Gbps FC SFPs are NOT supported in the DE Series controllers. ONLY
16Gbps and 32 Gbps FC SFPs are supported.
◦ If you have 10 Gbps SFPs, and you are converting host ports to FC, you must remove the
SFPs from these ports and replace them with dual-protocol or 16 Gbps SFPs after
converting the protocol.
