CNC ports used for host connection
AssuredSAN 4824/4834/4844/4854 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:
• 16 G b F C
• 8 Gb FC
• 4 Gb FC
• 10 GbE iSCSI
• 1 GbE iSCSI
Alternatively, 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
both16 Gbit/s or both 8 Gbit/s), and host ports 2 and 3 must be set to iSCSI (either both 10GbE or both
1 Gbit/s), provided the CNC ports use the qualified SFP connectors and cables required for supporting
the selected host interface protocol. See CNC technology on page 58 and
4824/4834/4844/4854 CNC controller module — rear panel LEDs on page 122 for more information.
TIP: See the Storage Management Guide for information about configuring CNC ports with host
interface protocols of the same type or a combination of types.
IMPORTANT: AssuredSAN 4824/4834/4844/4854 models ship with CNC ports initially configured for
FC. When connecting CNC ports to iSCSI hosts, you must use the CLI (not the SMC or RAIDar) to specify
which ports will use iSCSI. It is best to do this before inserting the iSCSI SFPs into the CNC ports (see
Change the CNC port mode on page 78 for instructions).
HD mini-SAS ports used for host connection
AssuredSAN 4524/4534/4544/4554 models provide four high-density mini-SAS (HD mini-SAS) 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 12 Gbit/s using the qualified connectors and cable options.
See 4524/4534/4544/4554 SAS controller module—rear panel LEDs on page 124 for more information.
