CNC ports used for host connection

Certain models use Converged Network Controller (CNC) technology, allowing you to select the desired host interface
protocol from the available Fibre Channel (FC) or Internet SCSI (iSCSI) host interface protocols supported by the system.
You can use the CLI to set all controller module CNC ports to use one of these host interface protocols:
• 16Gb FC
• 8Gb FC
• 4Gb FC
• 10GbE iSCSI
• 1GbE iSCSI
Alternatively, for 5005/4005 models you can use the CLI to set CNC ports to support a combination of host interface
protocols. When configuring a combination of host interface protocols, host ports 0 and 1 are set to FC (either both
16Gb/s or both 8Gb/s), and host ports 2 and 3 must be set to iSCSI (either both 10GbE or both 1Gb/s), provided the CNC
ports use qualified SFP connectors and cables required for supporting the selected host interface protocol.
See "CNC technology" (page 43)
TIP: See the CLI Reference Guide for information about configuring CNC ports with host interface protocols of the
same type or a combination of types.
CNC controller modules ship with CNC ports initially configured for FC. When connecting CNC ports to iSCSI hosts, you
must use the CLI (not the SMC) to specify which ports will use iSCSI. It is best to this before inserting the iSCSI SFPs into
the CNC ports (see

HD mini-SAS ports used for host connection

5005/4005 enclosures provide eight high-density mini-SAS ports (4-ports per controller module). The HD mini-SAS host
interface protocol uses the SFF-8644 external connector interface defined for SAS3.0 to support a link rate of 12Gb/s
using the qualified connectors and cable options. See
