AssuredSAN Ultra48 Series Setup Guide 11
About this guide
Overview
This guide provides information about initial hardware setup for the AssuredSAN™ Ultra48 Series storage
enclosure products listed below:
• CNC (Converged Network Controller) controller enclosure: 4844
• Qualified Fibre Channel SFP option supporting (4/8/16 Gb)
• Qualified Internet SCSI (10GbE) SFP option
• Qualified Internet SCSI (1 Gb) Copper RJ-45 SFP option
• HD mini-SAS (12 Gb) controller enclosure: 4544
AssuredSAN Ultra48 Series provides high-capacity storage enclosures supporting up to 48 2.5" small form
factor (SFF) disks in a 2U chassis. The chassis form factor supports controller enclosures and expansion
enclosures. Storage enclosures are equipped with dual I/O modules (IOMs); and they are equipped with
two AC power supply modules.
The Ultra48 Series controller enclosures can optionally be cabled to 4144 drive enclosures for adding
storage. A maximum of four enclosures (including the controller enclosure) are supported.

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:
• 16 Gb FC
• 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 33 and 4844 CNC controller module
— rear panel LEDs on page 78 for more information.
TIP: See the “Configuring host ports” topic within the RAIDar User Guide for information about
configuring CNC ports with host interface protocols of the same type or a combination of types.
IMPORTANT: AssuredSAN 4844 models ship with CNC ports initially configured for FC. When
connecting CNC ports to iSCSI hosts, you must use the CLI (not 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 48 for instructions).
