1. Introduction
This section presents brief overview of the SAS 6Gb/s host adapters:
ARC-1320-8i, ARC-1320-4i4x, ARC-1320-8x and ARC-1320ix-16.
1.1 Overview
The ARC-1320 SAS host adapters are a line of PCIe 2.0 x8 lanes
6Gb/s SAS bus low prole host adapters. The adapters bring the
fastest available connections to SAS/SATA storage on any com-
puter, workstation and server with PCI Express interface. ARC-1320
host adapters provide a blazing-fast storage connectivity solution
with enhanced reliability and performance and a wide variety of
internal and external connector congurations to support any appli-
cation and tiered storage solution. With connectivity options includ-
ing 8-internal ports, 4-internal/4-external ports, 8-external ports,
and 16-internal/8-external ports, ARC-1320 6Gb/s host adapters
are ideal for large capacity external server storage RAID and no-
RAID enclosure.
ARC-1320 6Gb/s SAS host adapters are able to connect to SATA
and SAS hard disk drives, allowing for tiered storage that optimizes
costs and performance. SAS drives are optimal when speed and
reliability are of the utmost concern while SATA drives are appro-
priate when capacity and cost are more important. System integra-
tors can use the ARC-1320 series to meet different storage infra-
structure applications that support both SAS and SATA devices. API
library for customer combines the ARC-1320 series function code to
its monitor utility.

The ARC-1320-4i4x,ARC-1320-8i or ARC-1320ix-16 host adapt-
ers have Mini SAS 4i internal connectors, each of them can sup-
port up to four SAS/SATA signals. These adapters can be installed
in a server RAID enclosure with Mini SAS 4i internal connectors
backplane. This Mini SAS 4i 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 efcient LED management and for sensing drive locate status.

The ARC-1320-4i4x, ARC-1320-8x or ARC-1320ix-16 host
adapters can support daisy-chain up to 128 end point devices
through external expander enclosures. The following gure
shows how to connect the external Mini SAS cable from the
ARC-1320-4i4x or ARC-1320ix-16 series host adapters that have
external SFF-8088 connectors to the external drive boxes or drive
enclosures.
Step 5. Install the LED Cable (option)
The preferred I/O connector for server backplanes is the Mini SAS
4i internal connector. This connector has eight signal pins to sup-
portfour SAS/SATA drives and six pins for the SGPIO (Serial Gener-
al Purpose Input/Output) side-band signals. The SGPIO bus is used
for efcient LED management and for sensing drive Locate status.
See SFF 8485 for the specication of the SGPIO bus. For backplane
without SGPIO supporting, Please use the individual 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 out-
side of the server by using light pipes mounted on the SAS drive
tray. A small microcontroller on the backplane, connected via the
SGPIO bus to a ARC-1320ix-16 could control the LEDs. Activity:
blinking 5 times/second and Fault: solid illuminated.

SideBand6 Reserved SideBand7 Reserved
Drive Locate Circuitry: The location of a drive may be detected by
sensing the voltage level of one of the pre-charge pins before and
after a drive is installed.
The following signals dene the SGPIO assignments for the Mini
SAS 4i internal connector (SFF-8087) in the SAS host adapters.
The pin assignment of the sideband inputs follow SFF-8448
specication.
The following signal denes the sideband header signals which can
work with Areca sideband cable on its SFF-8087 to 4 SATA cable.
The sideband header is located at backplane. For SGPIO to
work properly, please connect Areca 8-pin sideband cable to the
sideband header as shown below.
There is no SGPIO supported in the most of old version SATA
backplane. The ARC-1320ix-16/ARC-1320-4i4x/ARC-1320-8i host
adapters also provide 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 ARC-1320ix-16/ARC-
1320-4i4x/ARC-1320-8i host adapters logical of fault/activity
header. The signal for each pin is cathode (-) side.

LED Normal Status Problem Indication
Fault LED When the fault LED is solid
illuminated, there is no disk
present. When the fault LED
is off, then disk is present
and status is normal.
When the fault LED is slow blinking
(2 times/sec), that disk drive has
failed and should be hot-swapped
immediately. When the activity
LED is illuminated and fault LED is
fast blinking (10 times/sec) there
is rebuilding activity on that disk
drive.
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.
The following diagrams and descriptions describe each type of con
nector.
1: Individual Fault LED Connector
Most of the backplane has supported the HDD activity from the
HDD. The ARC-1320ix-16 SAS host adapter also provides the fault
connector for fault LED. Connect the cables for the drive fault LEDs
between the backplane of the cage and the respective connector on
the SAS host adapters.
The following table is the fault LED signal behavior.
