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. Using the set host-port-mode CLI command, you can set all controller module CNC
ports to use either FC or iSCSI protocol. The DS6200/DS4200/DS2200 controller enclosures support the following
link speeds:
• 16Gb FC
•
8Gb FC
•
4Gb FC
•
10GbE iSCSI
•
1GbE iSCSI
Alternatively, for 4-port DS6200/DS4200 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.
The 2-port DS2200 models do not support SFPs for multiple host interface protocols in combination. You must
select a common host interface protocol and SFP for use in all CNC ports within the controller enclosure.
See "CNC technology" (page
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 do this before
inserting the iSCSI SFPs into the CNC ports (see

HD mini-SAS ports used for host connection

DS6200/DS4200 enclosures provide eight high-density mini-SAS ports (4-ports per controller module). DS2200
enclosures provide four high-density (HD) mini-SAS ports (2-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
information.
