1. Introduction
This section presents a brief overview of the 12/16/24 bays external
Fibre/SAS/iSCSI to 12Gb/s SAS RAID subsystem.
1.1 Overview
The 12Gb/s SAS interface supports both 12Gb/s and 6Gb/s
SAS/SATA drives. The controllers attach directly to SATA/SAS
backplanes and can increase capacity using one additional Min
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 SAS JBODs.
The Fibre/SAS/iSCSI to 6Gb/s SAS RAID subsystem provides
a 2U/3U/4U rackmount external storage chassis capable of
accommodating up to 12/16/24 12.0-Gb/s, Serial-Attached SCSI
(SAS) drives or 6.0-Gb/s Serial ATA (SATA) drives. The redundant
controller model provides fault-tolerant links across separate host
interfaces, while the single controller model provides a single data
path.
Unparalleled Performance for 12Gb/s SAS
The 12Gb/s SAS RAID subsystems raise the standard to higher
performance levels with the latest Areca RAID controllers which
include several enhancements such as 1.2 GHz dual core ROC
processor and a DDR3-1866 memory architecture. The subsystem
includes one 240-pin DIMM socket with default 2GB DDR3-1866,
single rank, 1Rx8, upgradeable to 8GB DDR3-1600, dual rank,
2Rx8, ECC SDRAM. The 12Gb/s SAS is designed for backward
compatibility with 6Gb/s and 3Gb/s SAS and SATA hard drives.
The subsystem 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
subsystem buers 6Gb/s data and then transfers it out to the host

13
at 12Gb/s speeds in order to match the bandwidth between faster
hosts and slower SAS or SATA devices.
Unsurpassed Data Availability
The subsystems support hardware RAID 6 to allow two HDDs
failures without impacting the existing data. Users can hot swap
drives in the event of a drive failure with zero downtime. SATA,
SAS and SSDs are supported. The optional ash-based backup
module provides power to the controller cache to preserve data not
yet written to the drives when power is lost.
Easy RAID Management
Conguration and monitoring can be managed either through
the LCD control panel, RS232 port or LAN port. The rmware
contains an embedded terminal emulation via the RS-232 port.
The rmware-embedded web browser-based RAID manager allows
local or remote to access it from any standard internet browser via
a LAN port. The controller also supports API library for customers
to write their own monitoring utility. The Single Admin Portal (SAP)
monitoring utility lets you manage multiple RAID units in the
network with ease.
1.2 Subsystem Naming Rule
The model designation begins with the letter S for single controller
and the letter D for dual controller units. Note that the single
controller units can be upgraded to dual controllers at any time.
The 6000 series have SAS host interface while the 7000 series
have FC16 or 10gbE interfaces. For 7000 series the last letter is F
for Fibre Channel and E for 10gbE. The remaining digits describe
the chassis form factor (# of Us) and number of drive bays.

● Disk Slot Numbers
To perform a disk hot-plug procedure, you must know the
physical disk slot number for the drive that you want to install
or remove. The number on the drive tray above shows how
RAID subsystem disk slots are numbered. Disk slot number is
reected in the RAID manager interface.
● Drive Tray LED Indicators
Each drive tray in your subsystem has two LEDs: an activity
LED (blue) and one power/fault (two colors green/red) status
LED. The activity LED ashes whenever the drive is accessed.
The following table describes the SAS RAID subsystem drive
tray LED status.
LED Normal status Problem Indication
Blue LED
(Activity)
1. When the activity LED
is lit, there is I/O
activity on that disk
drive.
2. When the LED is not
lit; there is no activ-
ity on that disk drive.

Green/Red LED
(Power/Fault)
1. When the power LED
(green) is lit and fault
LED (red) is o, that
disk is present and
status normal.
2. When the fault LED is
lit there is no disk
present.
1. When the fault LED (red) is
blinking (2 times/sec), the disk
drive has failed and should be
hot-swapped immediately.
2. When the activity LED (blue) is
lit and fault LED (red) is fast
blinking (10 times/sec) there is
re-building activity on that
disk drive.

Fibre Host Port LED Status
Link LED
(Green/Orange light)
Two LEDs (green/orange) are used to indicate the link
speed of the operation of each Fibre Channel port.
1. On (green) when the Fibre Channel 16Gbps link
speed is connected and established.
2. On (orange) when the Fibre Channel 8Gbps link
speed is connected and established.
3. On (green and orange interactive ash) when the
Fibre Channel 4Gbps link speed is connected
and established.
Access LED
(Blue light)
The Fibre channel host accesses to the Fibre to SAS
RAID subsystem.
The following table describes the Fibre to SAS RAID subsystem
host channel link/access LED.

SAS Host Port LED Status
Link LED
(Green light)
1. When host port link LED is lit for 1 second and
turns o for 3 seconds that indicates the one link
has connected.
2. When host port link LED is lit for 2 seconds and
turns o for 2 seconds that indicates the two links
have connected.
3. When host port link LED is lit for 4 seconds that
indicates the four links have connected.
Access LED
(Blue light)
When access LED is lit that indicates the SAS host
accesses to the SAS to SAS RAID subsystem.

iSCSI Host Port Status
Link LED
(Green light)
When link LED is lit that indicates the iSCSI host link has
connected.
Access LED
(Blue light)
When activity LED is ashed that indicates the iSCSI
host accesses to the iSCSI RAID subsystem.
The following table describes the iSCSI to SAS RAID subsystem
host channel link and access LED.

Expander LED Status
Link LED
(Green light)
1. When link LED is lit for 1 second and turns o for 3 sec-
onds that indicates the one expander link has connected.
2. When link LED is lit for 2 seconds and turns o for 2
seconds that indicates the two expander links have
connected.
