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 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 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).

Front panel components
AssuredSAN Ultra48 Series supports 2U48 enclosures. The 2U48 chassis—configured with up to 48 2.5"
small form factor (SFF) disks—is used as either a controller enclosure or expansion enclosure.
Supported expansion enclosures are used for adding storage. The 4144 is the high-capacity 2U48 drive
enclosure used for adding storage. The 4144 is briefly described in this guide.
Storage enclosures support dual I/O modules (IOMs), and they are equipped with two redundant AC
power supply modules.
48-drive enclosure front panel components
Enclosure bezel installed
When the enclosure is in operation, the bezel should be installed on the front panel as shown in Figure 1.
The enclosure bezel is equipped with an EMI (Electromagnetic Interface) shield to provide protection for the
disks.
Figure 1 2U48 enclosure: front panel with bezel installed

Your 2U48 enclosure is shipped with the drawers installed, but they are not populated with disks.
Depending on the your product configuration, disk bay blanks—also known as Air Management Solution
(AMS) inserts—might be installed. Locate the box containing your sledded disks and AMS inserts (if
applicable) in preparation for populating the drive slots.
•See Table 3 on page 23 for sequential tasks required for successful enclosure installation.
•See Populating drawers on page 24 for instructions on installing disks and AMS inserts.

IMPORTANT: Disk drive slot numbering is also provided on the label that is laminated to the sheet metal
housing (top face) on each drawer. Refer to the drawer label when installing disks into the drawer.
Figure 4 below provides a sample partial configuration of disk bays within a drawer. The bay on the left is
populated with four disks, whereas the adjacent bay on the right contains an AMS insert to manage air
flow within the enclosure to maintain optimal operating temperature.
1The disk is oriented in the sled such that its PCBA faces upward on the top side of the disk drive module as shown.
2Electromagnetic interface protection for disk drives is provided by the EMI shield within the enclosure bezel.
3The AMS insert spans an entire disk bay (4 slots). A single disk slot AMS might become a future option.
Figure 4 2U48 enclosure: sample drawer population
IMPORTANT: Empty bays will cause overheating. To avoid overheating, install an AMS insert in disk bays
that do not contain quantity four disk drive modules.
Disk drives used in Ultra48 Series enclosures
Ultra48 Series enclosures support SFF Midline SAS, SFF Enterprise SAS, and SFF SSD disks. They also
support LFF/SFF Midline SAS and LFF/SFF Enterprise self-encrypting disks that work with the Full Disk
Encryption (FDE) feature. For information about creating vdisks and adding spares using different disk
drive types, see the AssuredSAN 4004 Series RAIDar User Guide or online help. Also see FDE
considerations on page 27.

Controller enclosure — rear panel layout
The diagram and table below display and identify important component items that comprise the rear panel
layout of an AssuredSAN Ultra48 Series controller enclosure. The 4844 is shown as a representative
example of 2U48 controller enclosure models included in the product series.
Figure 5 Ultra48 Series high-capacity controller enclosure: rear panel
A controller enclosure accommodates two AC power supply FRUs within the two power supply slots (see
two instances of callout No.1 above). The controller enclosure accommodates two controller module FRUs
of the same type within the I/O module (IOM) slots (see callouts No.3 and No.4 above).
IMPORTANT: Ultra48 Series controller enclosures support dual-controller configuration only.
Single-controller support is provided only when a controller fails over to its partner controller. A controller
module must be installed in each IOM slot to ensure sufficient airflow through the enclosure during
operation.
The diagrams with tables that immediately follow provide descriptions for the controller modules and
power supply modules that can be installed into the rear panel of an Ultra48 Series controller enclosure.
Showing controller modules and power supply modules separately from the enclosure enables improved
clarity in identifying the component items called out in the diagrams and described in the tables.
Descriptions are also provided for optional drive enclosures supported by Ultra48 Series controller
enclosures for expanding storage capacity.
NOTE: Ultra48 Series enclosures support hot-plug replacement of redundant controller modules, fans,
power supplies, and expansion modules. Hot-add replacement of drive enclosures is also supported.

4144 drive enclosure rear panel components
AssuredSAN Ultra48 Series controller enclosures support the high-capacity 2U48 drive enclosure for
adding storage. The 4144 expansion enclosure uses the same 2.5" SFF disk drive modules use by the
Ultra48 Series controller enclosures (see Figure 4 on page 17 for a visual representation of disk drive
modules and AMS inserts used by the 4144). The 4144 uses mini-SAS (SFF-8088) connectors to facilitate
back-end SAS expansion. See Cable requirements for storage enclosures on page 29 for cabling
information.
