INTRODUCTION
1. Introduction
This section presents a brief overview of the 12Gb/s SAS RAID controller, ARC-1883 series. (PCIe 3.0 to 12Gb/s SAS RAID controllers)
1.1 Overview
The 12Gb/s SAS interface supports both 12Gb/s SAS disk drives
for data-intensive applications and 6Gb/s SATA drives for low-cost
bulk storage of reference data. The ARC-1883 family includes 8
ports low profile as well as 12/16/24 internal ports with additional
4 external ports models. The ARC-1883LP/1883i/1883x support
eight 12Gb/s SAS ports via one internal & one external/two internal/two external Mini SAS HD connector. The ARC-1883ix-12/16/24
attaches directly to SATA/SAS midplanes with 3/4/6 Mini SAS HD
SFF-8643 internal connector or increase capacity using one additional Mini SAS HD SFF-8644 external connector. When used with
12Gb/s SAS expanders, the controller can provide up to (256) devices through one or more 12Gb/s SAS JBODs, making it an ideal
solution for enterprise-class storage applications that called for
maximum configuration flexibility.
ARC-1883i/LP/x 12Gb/s RAID controllers are low-profile PCIe cards,
ideal for 1U and 2U rack-mount systems. These controllers utilize
the same RAID kernel that has been field-proven in existing external RAID controller products, allowing Areca to quickly bring stable
and reliable PCIe 3.0 12Gb/s SAS RAID controllers to the market.
Unparalleled Performance for 12Gb/s SAS
The 12Gb/s SAS RAID controllers raise the standard to higher performance levels with several enhancements including new high performance 1.2 GHz dual core ROC processor, a DDR3-1866 memory
architecture and high performance PCIe 3.0 interface bus interconnection. The low profile controllers by default support on-board 2G
of ECC DDR3-1866 SDRAM memory. ARC-1883ix-12/16/24 RAID
controllers each include one 240-pin DIMM socket with default 2GB
DDR3-1866, single rank, 1Rx8, upgrade to 8GB or 8GB DDR31600, dual rank, 2Rx8, ECC SDRAM. The 12Gb/s SAS is designed
for backward compatibility with 6Gb/s and 3Gb/s SAS/SATA hard

INTRODUCTION
drives. Regardless of the drive speed, 12Gb/s SAS RAID controllers
will provide maximum read/write performance improvements for
the most performance-hungry database and IT applications.
The ARC-1883ix includes one 12Gb/s SAS expander that incorporates the latest enhancements in SAS along with new LSI DataBolt
bandwidth optimizer technology. This is designed to help facilitate
the industry transition to 12Gb/s SAS-enabled systems by allowing users to take advantage of 12Gb/s speeds while utilizing existing 6Gb/s drives and backplanes. Using DataBolt, the ARC-1883ix
buffers 6Gb/s data and then transfers it out to the host at 12Gb/s
speeds in order to match the bandwidth between faster hosts and
slower SAS or SATA devices
Unsurpassed Data Availability
Designed and leveraged with Areca’s existing high performance
RAID solution, ARC-1883 provides superior levels performance
and enterprise level data protection for the most demanding nextgeneration server and storage environments. It supports the hardware RAID 6 engine to allow two HDDs failures without impact the
existing data and performance. It allows users to hot swap drive in
the event of a drive failure with zero downtime. The optional flashbased backup module provides power to transfer the cache data
from the SDRAM memory to the NAND flash memory if it contains
data not yet written to the drives when power is lost. ARC-1883
also supports traditional Lithium-ion (Li-ion) battery backup module (BBM) to protect cached data on RAID adapters. Board-level
hardware encryption manages any kinds of drives attached to ARC1883 controller cards for higher levels of security. API code supports for third-party Enterprise Key Management systems to easy
integrate and manage encryption function.
Maximum Interoperability
The 12Gb/s SAS RAID controller support broad operating system
including Windows, Linux (Open Source), FreeBSD (Open Source),
Solaris (Open Source), Mac, VMware and more, along with key
system monitoring features such as enclosure management (SES2, SMP, & SGPIO) and SNMP function. Our products and technology
are based on extensive testing and validation process; leverage

installed. Be sure that the power is connected to either the cage
backplane or the individual drives.
In the backplane solution, SAS/SATA drives are directly connected
to 12Gb/s SAS system backplane or through an expander board.
The number of SAS/SATA drives is limited to the number of slots
available on the backplane. Some backplanes support daisy chain
expansion to the next backplanes. The 12Gb/s SAS RAID controller
can support daisy-chain up to 8 enclosures. The maximum drive
no. is 256 devices through 8 enclosures. The following figure shows

HARDWARE INSTALLATION
Step 7. Connect Power to the Controller (ARC-1883ix only)
There is a 6-pin PCI-E connector on the ARC-1883ix labelled J4.
You must plug in a PSU’s PCI-E cable at all times to supply enough
stable power for the controller.
Figure 2-9, Connect Direct from Power Supply
If your power supply doesn’t have a 6 pin PCI-E power cable then
you can use the adapter to convert two 4 pin peripheral power
cables into a PCI-E power cable. If you use an adapter then be sure
to plug the 4 pin peripheral power connectors into separate power
cables coming from the power supply.

HARDWARE INSTALLATION
Figure 2-10, Connect through HDD/CD Cable
Step 8. Install the LED Cable (Optional)
The preferred I/O connector for server backplanes is the Mini SAS
HD SFF-8643 connector. This connector has eight signal pins to
support four SAS/SATA drives and six pins for the SGPIO (Serial
General Purpose Input/Output) side-band signals. The SGPIO bus
is used for efficient LED management and sensing drive locate
status. See SFF 8485 for the specification of the SGPIO bus. For
backplane without enclosure SGPIO support, please refer to section
2.4 LED cables for fault/activity LED cable installation.
LED Management: The backplane may contain LEDs to indicate
drive status. Light from the LEDs could be transmitted to the outside of server by using light pipes mounted on the SAS drive tray.
A small microcontroller on the backplane, connected via the SGPIO
bus to a 12Gb/s SAS RAID controller, could control the LEDs. Activity: blinking 5 times/second and Fault: lit

• Driver installation usually takes places as part of operating system installation. Please refer to Chapter 4 “Diver Installation” of
the user manual for the detailed installation procedure.
In an existing system:
• To install the controller driver into the existing operating system.
For the detailed installation procedure, please refer to the Chapter 4 “Driver Installation” of the user manual.
Step 13. Install ArcHTTP Proxy Server
The 12Gb/s SAS RAID controller firmware has embedded the
web-browser McRAID storage manager. ArcHTTP proxy server will
launch the web-browser McRAID storage manager. It provides all of
the creation, management and monitor 12Gb/s SAS RAID controller status. Please refer to the Chapter 5 of the user manual for the
detail ArcHTTP Proxy Server Installation. For SNMP agent function,
please refer to Appendix D of the user manual.
Step 14. Configure Volume Set
The controller configures RAID functionality through the McBIOS
RAID manager. Please refer to Chapter 3 of the user manual, McBIOS RAID Manager, for the detail. The RAID controller can also
be configured through the McRAID storage manager with ArcHTTP
proxy server installed or through on-board LAN port and LCD module (refer to LCD manual). For McRAID storage manager option,
please refer to Chapter 6 of the user manual, Web Browser-Based
Configuration.

HARDWARE INSTALLATION
Step 15. Determining the Boot Sequences
For PC system:
12Gb/s SAS RAID controller is a bootable controller. If your system already contains a bootable device with an installed operating
system, you can set up your system to boot a second operating
system from the new controller. To add a second bootable controller, you may need to enter setup of motherboard BIOS and change
the device boot sequence so that the new RAID controller heads
the list. If the system BIOS setup does not allow this change, your
system may be not configurable to allow the 12Gb/s SAS RAID
controller to act as a second boot device.
For Intel-based Mac system:
Areca controller has supported the EFI BIOS on the PCIe 3.0
12Gb/s SAS RAID controller. You have other alternatively to add
volumes on the Intel-based Mac bootable device listing. You can
follow the following procedures to add 12Gb/s SAS RAID controller
on the Mac bootable device listing.
1. Set the BIOS selection in System Controls: Advance Configuration to “EFI” option for Intel-based MacPro boot.
2. Download OS X Mavericks and DiskMaker X. Follow the DiskMaker X to make a bootable OS X Mavericks USB install drive.
3. Restart your Mac and after you hear the chime sound, press
the Option (Alt) key until you see the option to choose the
flash drive to boot from.
4. Follow the on-screen prompts to complete Areca Volume
Upgrade and Clean Install of OS X Mavericks. Power up the
Intel-based Mac and Areca volume will be added in the
bootable device automatically.

HARDWARE INSTALLATION
2.4 SAS Cables
You can connect the end devices to each other through direct
cables or through the SAS expander/backplane connections. The
12Gb/s SAS RAID controller supports daisy-chain expansion up to 8
enclosures. The following is an example of some internal SAS/SATA
cables and an external SAS cable.
2.4.1 Mini SAS HD SFF-8643 to 4xSATA Cable
The Mini SAS HD SFF-8643 to 4xSATA cables are used for connection between the 12Gb/s SAS RAID controller internal connectors
and connectors on the SAS/SATA disk drives or SAS/SATA connector backplane. The 12Gb/s SAS controllers have 1-6 Mini SAS
HD SFF-8643 internal connectors, each of them can support up to
four SAS/SATA drives.
These controllers can be installed in a server RAID enclosure
with standard SATA connectors backplane. The following diagram
shows the picture of Mini SAS HD SFF-8643 to 4xSATA cables.
Backplane with SGPIO header can leverage the SGPIO function on
the 12Gb/s SAS RAID controller through the sideband cable.
The SFF-8448 sideband signals cable is reserved for the backplane with header on it.

HARDWARE INSTALLATION
2.4.2 Mini SAS HD SFF-8643 to 4xSFF-8482 Cable
These controllers can be installed in a server RAID enclosure with
out a backplane. The kind of cable will attach directly to the SAS
disk drives. The following diagram shows the picture of Mini SAS
HD SFF-8643 to 4xSFF-8482 cables.
Figure 2-12, SFF-8643 to 4xSFF-8482 Cable
2.4.3 Mini SAS HD SFF-8643 Cable
The 12Gb/s SAS RAID controllers have 1-6 Mini SAS HD SFF-8643
connectors, each of them can support up to four SAS/SATA signals. These controllers can be installed in a server RAID enclosure
with Mini SAS HD SFF-8643 internal connectors backplane. This
Mini SAS HD cable has eight signal pins to support four SAS/SATA
drives and six pins for the SGPIO (Serial General Purpose Input/
Output) side-band signals. The SGPIO bus is used for efficient
LED management and sensing drive Locate status.

HARDWARE INSTALLATION
2.4.4 Mini SAS HD SFF-8644 Cable
The Mini SAS HD SFF-8644 cables are used for connection between the 12Gb/s SAS controller external connectors and connectors on the external drive boxes or drive expanders (JBOD).
The 12Gb/s SAS controller has Mini SAS HD SFF-8644 external
connector, each of them can support up to four SAS/SATA signals.
Figure 2-14, Mini SAS HD SFF-8644 Cable
2.5 LED Cables
There is no SGPIO supported in the most of old version SATA
backplane. The 12Gb/s SAS controller also provides two kinds of
alternative LED cable header to support the fault/activity status
for those backplanes. The global indicator connector is used by the
server global indicator LED.
The following electronics schematic is the 12Gb/s SAS RAID controller logical of fault/activity header. The signal for each pin is
cathode (-) side. The following diagrams and descriptions describe
each type of indicator connector.
27
HARDWARE INSTALLATION
1. Individual Activity/Fault LED and Global Indicator Connector
Most of the backplane has supported the HDD activity from the
HDD. The 12Gb/s SAS RAID controller also provides the fault
activity for fault LED. Connect the cables for the drive fault LEDs
between the backplane of the cage and the respective connector
on the 12Gb/s SAS RAID controller.
The following table is the fault LED signal behavior.
LED
Fault LED
Normal Status
1. When the fault LED is lit,
there is no disk present.
2. When the fault LED is not
lit, then disk is present
and status is normal.
Problem Indication
1. When the fault LED is blinking
(2 times/sec), that disk drive
has failed and should be hot
swapped immediately.
2. When the activity LED is lit and
fault LED is fast blinking (10
times/sec) there is rebuilding
activity on that disk drive.
If the system will use only a single global indicator, attach the
LED to the two pins of the global activity/fault connector. The
global fault pin pair connector is the overall fault signal. This
signal will light up in any disk drive failure.

HARDWARE INSTALLATION
Note:
A cable for the global indicator comes with your computer
system. Cables for the individual drive LEDs may come with a
drive cage, or you may need to purchase them.
2. Areca Serial Bus Connector
You can also connect the Areca interface to a proprietary SAS/
SATA backplane enclosure. This can reduce the number of
activity LED and/or fault LED cables. The I2C interface can also
cascade to another SAS/SATA backplane enclosure for the
additional channel status display.

HARDWARE INSTALLATION
Areca serial bus also supports SES (SCSI Enclosure Services) over
I2C over internal I2C backplane cable. The backplane cable can
connect the I2C signal from Areca controller to the backplane using
IPMI-style I2C 3-pin connector. It means you link I2C cable into back
plane, and let back plane LED indicate hard disk drive fail status.
2.5 Hot-plug Drive Replacement
The RAID controller supports the ability of performing a hot-swap
drive replacement without powering down the system. A disk can
be disconnected, removed, or replaced with a different disk without
taking the system off-line. The RAID rebuilding will be processed
automatically in the background. When a disk is hot swap, the
RAID controller may no longer be fault tolerant. Fault tolerance will
be lost until the hot swap drive is subsequently replaced and the
rebuild operation is completed.
2.5.1 Recognizing a Drive Failure
A drive failure can be identified in one of the following ways:
1. An error status message lists failed drives in the event log.
2. A fault LED illuminates on the front of RAID subsystem if
failed drives are inside.
2.5.2 Replacing a Failed Drive
With RAID subsystem drive tray, you can replace a defective
physical drive while your computer is still operating. When a new
drive has been installed, data reconstruction will be automatically
started to rebuild the contents of the disk drive. The controller
always uses the smallest hotspare that “fits”. If a hotspare is used
and the defective drive is exchanged on-line, the new inserted
HDD will automatically assign as a hotspare HDD.
Note:
The capacity of the replacement drives must be at least
as large as the capacity of the other drives in the raid set.
Drives of insufficient capacity will be failed immediately by
the RAID controller without starting the “Automatic Data
Rebuild”.

McRAID Storage Manager
Before launching the firmware-embedded web browser, McRAID
storage manager through the PCIe bus, you need first to install the
ArcHTTP proxy server on your server system. If you need additional
information about installation and start-up of this function, see the
McRAID Storage Manager section in Chapter 6 of the user manual.
32
HARDWARE INSTALLATION
ArcHTTP Proxy Server
ArcHTTP has to be installed for GUI RAID console (MRAID
storage manager) to run. It is used to launch the web browser
McRAID storage manager. It also runs as a service or daemon
in the background that allows capturing of events for mail and
SNMP traps notification. If you need additional information about
installation and start-up of this function, see the ArcHTTP Proxy
Server Installation section in Chapter 5 of the user manual.
CLI Utility
CLI (Command Line Interface) lets you set up and manage RAID
controller through a command line interface. CLI performs many
tasks at the command line. You can download CLI manual from
Areca website or software CD <CDROM>\ DOCS directory.
SNMP Manager Console Integration
There are two ways to transport SNMP data on the 12Gb/s SAS
RAID controller: in-band PCIe host bus interface or out-of-band
built-in LAN interface. Enter the “SNMP Tarp IP Address” option on
the firmware-embedded SNMP configuration function for user to
select the SNMP data agent-side communication from the out-ofband built-in LAN interface. To use in-band PCIe host bus interface,
keep blank on the “SNMP Tarp IP Address” option.
• Out of Band-Using LAN Port Interface
Out-of-band interface refers to transport SNMP data of 12Gb/s
SAS controllers from a remote station connected to the controller through a network cable. Before launching the SNMP manager
on the client, you need firstly to enable the firmware-embedded
SNMP agent function and no additional agent software inquired
on your server system. If you need additional information about
installation and start-up this function, see the section 6.8.4
“SNMP Configuration” of the user manual.
• In-Band-Using PCIe Host Bus Interface
In-band interface refers to management of the SNMP data of
12Gb/s SAS controllers from a PCIe host bus. In-band interface
is simpler than out-of-band interface for it requires less hard-

HARDWARE INSTALLATION
ware in its configuration. Since the 12 Gb/s SAS RAID controller
is already installed in the host system, no extra connection is
necessary. Just load the necessary in-band Areca SNMP extension
agent for the controllers. Before launching the SNMP agent in
the sever, you need first to enable the firmware-embedded SNMP
community configuration and install Areca SNMP extension agent
in your server system. If you need additional information about
installation and start-up the function, see the SNMP Operation &
Installation section in the Appendix D of the user manual.
Single Admin Portal (SAP) Monitor
This utility can scan for multiple RAID units on the network and
monitor the controller set status. For additional information, see
the utility manual (SAP) in the packaged CD or download it from
the web site http://www.areca.com.tw.
