When an E2600 controller-drive tray has a 10-Gb/s iSCSI HIC, some restrictions apply to
Note:
the types of cables you can use for host cabling. The previous table shows the types and lengths of
cables that you can use. Do not use Category 5e cables or Category 6 cables.
Note: On the E2600 controller-drive tray, each controller has a pair of levers with handles for
removing the controller from the controller-drive tray. If a controller has a HIC installed, one of
these handles on the controller is located next to a host port on the HIC. The close spacing between
the handle and the host port might make it difficult to remove a cable that is attached to the host
port. If this problem occurs, use a flat-blade screwdriver to compress the release on the cable
connector.
E2800 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 are might be Fibre
Channel or iSDSI. 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 an E2800 or an E2700 controller shelf must have the same configuration of ports
and protocols.
E5600 storage arrays (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
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.
