Optical cables for 1-Gb/s iSCSI connections require a 1-Gb/s SFP.
2
Copper cables with RJ-45 connectors for iSCSI connections require an SFP adapter.
E2800, E5700, and E2700 controller shelves can have a mix of interface types. The HIC interface
might be different from that of the base ports. The base ports on an E2800 controller shelf might be
Fibre Channel or iSCSI. The E5700 utilizes iSCSI or Fibre Channel base ports. The base ports on an
E2700 are SAS.
You can also configure a HIC with four optical ports to have two Fibre Channel and two iSCSI ports.
Each controller in a controller shelf must have the same configuration of ports and protocols.
E5600 controller-drive trays (E5612, E5624, and E5660) and EF560 flash arrays support a four-port
HIC that might be configured with four Fibre Channel ports, four iSCSI ports, or with two ports for
Fibre Channel and two ports for iSCSI (split mode). If you have a HIC installed with all four ports
configured for the same protocol, you can apply a feature pack in SANtricity Storage Manager to
convert the protocol of the host ports to Fibre Channel-iSCSI split mode. Unified SFPs are available
that support both 16-Gb/s Fibre Channel and 10-Gb/s iSCSI. In
split mode, ports 1 and 2 on both
HICs operate as iSCSI ports, while ports 3 and 4 on both HICs operate as Fibre Channel ports. You
can also convert all four ports on a HIC from one protocol to the other. The following figure shows
the rear view of the E5612 controller-drive tray with two four-port HICs installed.

A host can have both iSCSI and Fibre Channel adapters for connections to a storage array that has a
mix of host port protocols. Several restrictions apply to such configurations:
•
The root boot feature is not supported for hosts with mixed connections to one storage array.
•
Cluster configurations are supported for hosts with mixed connections to one storage array.
•
When the host operating system is VMware, mixing connection types within a storage partition is
not supported.
