Page 11: About This Guide
CNC ports used for host connection AssuredSAN 4844 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 Command-line Interface (CLI) to set all controller module CNC ports to use one of these host interface protocols: •... -
Page 12: Hd Mini-Sas Ports Used For Host Connection
HD mini-SAS ports used for host connection AssuredSAN 4544 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 4544 SAS controller module—rear panel LEDs on page 80 for more information. -

Configuring host ports). CNC technology AssuredSAN 4844 models use Converged Network Controller technology, allowing you to select the desired host interface protocol(s) from the available FC or iSCSI host interface protocols supported by the system. The small form-factor pluggable (SFP transceiver or SFP) connectors used in CNC ports are further described in the subsections below. -
Page 34: Fibre Channel Protocol
IMPORTANT: Use the set host-port-mode CLI command to set the host interface protocol for CNC ports using qualified SFP options. AssuredSAN 4844 models ship with CNC ports configured for FC. When connecting CNC ports to iSCSI hosts, you must use the CLI (not RAIDar) to specify which ports will use iSCSI. -
