The ArcHttp proxy server is provided on the software CD delivered
with 6Gb/s SATA RAID controller or download from the www.areca.
com.tw. The rmware embedded McRAID storage manager can
congure and monitor the 6Gb/s SATA RAID controller via ArcHttp
proxy server. The Archttp proxy server for Mac pro, please refer to
Chapter 4.6 "Driver Installation" for Mac 10.X.
5.6 ArcHttp Conguration
The ArcHttp proxy server will automatically assign one additional
port for setup its conguration. If you want to change the "archttpsrv.conf" setting up of ArcHttp proxy server conguration, for
example: General Conguration, Mail Conguration, and SNMP
Conguration, please start Web Browser http:\\localhost: Cfg Assistant. Such as http:\\localhost: 81. The port number for rst controller McRAID storage manager is ArcHttp proxy server congura-
tion port number plus 1.
•General Conguration:
Binding IP: Restrict ArcHttp proxy server to bind only single
interface (If more than one physical network in the server).
HTTP Port#: Value 1~65535.
Display HTTP Connection Information To Console: Select “Yes" to
show Http send bytes and receive bytes information in the console.
Scanning PCI Device: Select “Yes” for ARC-1XXX series controller.
To enable the controller to send the email function, you need to
congure the SMTP function on the ArcHttp software. To enable
the RAID controller email sending function, click on the “Mail Conguration” link. The "SMTP Server Congurations" menu will show
as following:
When you open the mail conguration page, you will see the
following settings:
(1). SMTP Server Conguration:

(3). Event Notication Congurations:
MailTo Name: Enter the alert receiver name that will be shown on
the outgoing mail.
Mail Address: Enter the alert receiver mail address.
Ex: admin@areca.com.tw.
According to your requirement, set the corresponding event level :
Disable Event Notication: No event notication will be sent.
Urgent Error Notication: Send only urgent events.
Serious Error Notication: Send urgent and serious events.
Warning Error Notication: Send urgent, serious and warning
events.
Information Notication: Send all events.
Notication For No Event: Notify user if no event occurs within 24
hours.
•SNMP Traps Conguration:
To enable the RAID controller to send the SNMP traps to client
SNMP manager using the IP address assigned to the operating
system, such as Net-SNMP manager, you can simply use the SNMP
function on the ArcHttp proxy server software. To enable the
RAID controller SNMP traps sending function, click on the “SNMP
Conguration” link. The Archttp proxy only provide one direction
to send the trap to the SNMP manager without needing to install
the SNMP extension agent on the host. If SNMP manager requests
to query the SNMP information from RAID controller, please refer
the Appendix C "SNMP Operation & Installation". The “SNMP traps
Conguration” menu will be shown as following:
113
ARCHTTP PROXY SERVER INSTALLATION
When you open the SNMP traps conguration page, you will see the
following settings:
(1). SNMP Trap Congurations
Enter the SNMP trap IP address.
(2). SNMP System Congurations
Community name acts as a password to screen accesses to the
SNMP agent of a particular network device. Type the community
names of the SNMP agent in this eld. Before access is granted to
a request station, this station must incorporate a valid community
name into its request; otherwise, the SNMP agent will deny access
to the system. Most network devices use “public” as default of their
community names. This value is case-sensitive.
(3). SNMP Trap Notication Congurations
Before the client side SNMP manager application accepts the 6Gb/
s SATA RAID controller traps, it is necessary to integrate the MIB
into the management application’s database of events and status
indicator codes. This process is known as compiling the MIB into
the application. This process is highly vendor-specic and should be
well-covered in the User’s Guide of your SNMP application. Ensure
the compilation process successfully integrates the contents of the
areca_SATA.mib le into the traps database. Please refer to Appen-
dix C of “SNMP Operation & Installation”. The MIBs le resides at:
<CD-ROM>\packages\SNMP_MIBs on the software CD.
Note:
Event Notication Table refer to Appendix D.
After you conrm and submit congurations, you can use
"Generate Test Event" feature to make sure these settings are
correct.
• Rescan Device Conguration:
Let's assume you've put all Areca RAID adapters to a system.
The Archttp scans the RAID adapters on the system and create
an individual adapter icon located on left column of the Archttp
Congurations screen. This adapter icon is for user to launch web
browser RAID manager. If there is any RAID adapter missed on the
system start-up, you can use the "Rescan Device" function. The
114
ARCHTTP PROXY SERVER INSTALLATION
"Rescan Device" function is a procedure which forces the archttp to
rescan the targets to allow a missed RAID adapter to be added.
• Collect Support Data:
Areca has added the “Collect Support Data” option on the Archttp
proxy server utility to download a support le (le name:ctlrxxxxxxx.log) with all necessary information (system information,
conguration, disk information, eventlog). The “Collect Support
Data” function will be automatically started when ERROR or
SERIOUS event has occurred.

6. Web Browser-based Conguration
Before using the rmware-based browser McRAID storage manager, do
the initial setup and installation of this product. If you need to boot up
the operating system from a RAID volume set, you must rst create a
RAID volume by using McBIOS RAID manager. Please refer to section
3.3 “Using Quick Volume /Raid Setup” conguration for information on
creating this initial volume set.
The McRAID storage manager is rmware-based utility, which is accessible via the web browser installed on your operating system. The web
browser-based McRAID storage manager is a HTML-based application,
which utilizes the browser (IE, Safari, Netscape and Mozilla etc) installed on your monitor station.
It can be accessed through the in-band PCIe 2.0 bus or out-of-band
LAN port. The in-band method can launch the web browser-based
McRAID storage manager via archttp proxy server. The rmware-
embedded web browser-based McRAID storage manager allows local
or remote to access it from any standard internet browser via a LAN
or WAN with no software or patches required. The rmware contains
SMTP manager monitors all system events and user can select either
single or multiple user notications to be sent via LAN with “Plain English” e-mails. The rmware-embedded SNMP agent allows remote to
monitor events via LAN with no SNMP agent required.

appear for you to have chance to modify RAID level or stripe size.
Follow the instruction presented in the “Modify Volume Set ” to
modify the volume sets; operation system specic utilities may be
required to expand operating system partitions.
Note:
1. Once the “Expand Raid Set” process has started, user can
not stop it. The process must be completed.
2. If a disk drive fails during RAID set expansion and a hot
spare is available, an auto rebuild operation will occur after
the RAID set expansion completes.
3. RAID 30/50/60 does not support the "Expand Raid set".
4. RAID set expansion is a quite critical process, we strongly
recommend customer backup data before expand. Unex-
pected accident may cause serious data corruption.
6.5.4 Ofine Raid Set
This function is for customer being able to unmount and remount
a multi-disk volume. All Hdds of the selected RAID set will be put

6.6 Volume Set Functions
A volume set is seen by the host system as a single logical device.
It is organized in a RAID level with one or more physical disks.
RAID level refers to the level of data performance and protection of
a volume set. A volume set capacity can consume all or a portion
of the disk capacity available in a RAID set. Multiple volume sets
can exist on a group of disks in a RAID set. Additional volume sets
created in a specied RAID set will reside on all the physical disks
in the RAID set. Thus each volume set on the RAID set will have its
data spread evenly across all the disks in the RAID set.
The following summaries are the volume set features for the 6Gb/s
SATA RAID controller.
1. Volume sets of different RAID levels may coexist on the same
RAID set and up to 128 volume sets per controller.
2. Up to 128 volume sets can be created in a RAID set.
3. The maximum addressable size of a single volume set is not limited to 2TB, because the controller is capable of 64-bit LBA mode.
However the operating system itself may not be capable of addressing more than 2TB.
See Areca website ftp://ftp.areca.com.tw/RaidCards/Docu-
ments/Manual_Spec/ Over2TB_050721.ZIP le for details.
6.6.1 Create Volume Set (0/1/10/3/5/6)
To create volume set from RAID set system, move the cursor bar
to the main menu and click on the “Create Volume Set” link. The
“Select The Raid Set To Create On It” screen will show all RAID
set number. Tick on a RAID set number that you want to create

The new create volume set attribute allows user to select the
Volume Name, RAID Level, Capacity, Greater Two TB Volume
Support, Initialization Mode, Strip Size, Cache Mode, Tagged
Command Queuing, and SCSI Channel/SCSI ID/SCSI Lun.
127
WEB BROWSER-BASED CONFIGURATION
• Volume Name
The default volume name will always appear as “ARC-12x4-VOL”.
You can rename the volume set providing it does not exceed the
15 characters limit.
• Volume Raid Level
Set the Raid Level for the volume set. Highlight the desired
RAID level from the available RAID levels option.
• Capacity
The maximum volume size is the default initial setting. Enter the
appropriate volume size to t your application.
• Greater Two TB Volume Support
If volume capacity will exceed 2TB, controller will show the
"Greater Two TB Volume Support" sub-menu. Greater Two TB
Volume Support option: "No", "64bit LBA" and "4K Block".
- No
It keeps the volume size with max. 2TB limitation.
- 64bit LBA
This option uses 16 bytes CDB instead of 10 bytes. The
maximum volume capacity is up to 512TB.
This option works on different OS which supports 16 bytes CDB.
Such as:
Windows 2003 with SP1 or later
Linux kernel 2.6.x or later
128
WEB BROWSER-BASED CONFIGURATION
- 4K Block
It changes the sector size from default 512 bytes to 4k bytes.
The maximum volume capacity is up to 16TB. This option works
under Windows platform only. And it can not be converted to
“Dynamic Disk”, because 4k sector size is not a standard format.
For more details, please download Over2TB manual from
http://www.areca.com.tw/support/main.htm
• Initialization Mode
This option is used to dene “Background Initialization”, “Foreground Initialization” or “No Init (To Rescue Volume)”. When
“Background Initialization”, the initialization proceeds as a
background task, the volume set is fully accessible for system
reads and writes. The operating system can instantly access to
the newly created arrays without requiring a reboot and waiting
the initialization complete. When “Foreground Initialization”, the
initialization proceeds must be completed before the volume set
ready for system accesses. There is no initialization happened
when you select “No Init” option. “No Init“ is for customer to
rescue volume without losing data in the disk.
• Stripe Size
This parameter sets the size of the stripe written to each disk
in a RAID 0, 1, 10, 5, 6, 50 or 60 logical drive. You can set the
stripe size to 4 KB, 8 KB, 16 KB, 32 KB, 64 KB, 128 KB, 256KB,
512KB, or 1024KB. A larger stripe size produces better read
performance, especially if your computer does mostly sequential
reads. However, if you are sure that your computer does random reads more often, select a smaller stripe size.
Note:
RAID level 3 and 30 can’t modify the cache strip size.
• Cache Mode
The 6Gb/s SATA RAID controller supports “Write Through” and
“Write Back” cache.
129
WEB BROWSER-BASED CONFIGURATION
•Volume Write Protection
When "Volume Write Protection" is enabled on the "Modify
Volume Set", host commands fail if they are issued to a volume
in that RAID controller and attempt to modify a volume's data
or attributes. Volume Write Protection is used primarily for
customer-initiated disaster recovery testing.
• Volume IO Mode:
The Cache IO and Direct IO cache policies apply to read on a
specic virtual disk. The volume IO mode options are as follows:
- Cache Io
Species that all reads are buffered in the controller cache
memory.
- Direct Io
Species that reads are not buffered in cache memory. When
using direct IO mode, data is transferred to the controller cache
memory and the host system simultaneously during a read
request.
If a subsequent read request requires data from the same data
block, it can be read directly from the controller cache memory.
• Tagged Command Queuing
The “Enabled” option is useful for enhancing overall system
performance under multi-tasking operating systems. The
Command Tag (Drive Channel) function controls the SATA
command tag queuing support for each drive channel. This
function should normally remain “Enabled”. “Disabled” this
function only when using SATA drives that do not support
command tag queuing.
• SCSI Channel/SCSI ID/SCSI Lun
SCSI Channel: The 6Gb/s SATA RAID controller function is simulated as an external SCSI RAID controller. The host bus is represented as a SCSI channel. Choose the SCSI Channel.
SCSI ID: Each SCSI device attached to the SCSI card, as well
as the card itself, must be assigned an unique SCSI ID number.
A SCSI channel can connect up to 15 devices. The 6Gb/s SATA
RAID controller is a large SCSI device. Assign an ID from a list
of SCSI IDs.
130
WEB BROWSER-BASED CONFIGURATION
SCSI LUN: Each SCSI ID can support up to 8 LUNs. Most 6Gb/s
SATA controllers treat each LUN like a SATA disk.

6.6.4.2 Volume Set Migration
Migrating occurs when a volume set is migrating from one RAID
level to another, when a volume set strip size changes, or when
a disk is added to a RAID set. Migration state is displayed in the
volume state area of the “Volume Set Information” screen.

Note:
1. If the volume is RAID level 30, 50, or 60, you can not
change the volume to another RAID level. If the volume
is RAID level 0, 1, 10(1E), 3, 5, or 6, you can not change
the volume to RAID level 30, 50, or 60.
2.Power failure may damage the migration data. Please
backup the RAID data before you start the migration
function.
6.6.5 Check Volume Set
To check a volume set from a RAID set:
(1). Click on the “Check Volume Set” link.
(2). Click on the volume set from the list that you wish to check.
Click on “Conrm The Operation” and click on the “Submit” button. Use this option to verify the correctness of the redundant
data in a volume set. For example, in a system with dedicated
parity, volume set check means computing the parity of the data
disk drives and comparing the results to the contents of the
dedicated parity disk drive. The checking percentage can also be
viewed by clicking on “RAID Set Hierarchy” in the main menu.
6.6.6 Schedule Volume Check
A volume check is a process that veries the integrity of redundant data. To verify RAID 3, 5, 6, 30, 50 or 60 redundancy, a
volume check reads all associated data blocks, computes parity,
reads parity, and veries that the computed parity matches the
read parity.
Volume checks are very important because they detect and correct parity errors or bad disk blocks in the drive. A consistency
check forces every block on a volume to be read, and any bad
blocks are marked; those blocks are not used again. This is critical and important because a bad disk block can prevent a disk
rebuild from completing. We strongly recommend that you run
consistency checks on a regular basis—at least once per week (
set on ‘Scheduler). Volume checks degrade performance, so you
can also run them when the system is idle (set by “Checking After
System Idle”).

Note:
Please make sure of the inconsistency source generated
by parity error or bad block before you click the recovery
method. Otherwise, you will lose the recovery data.
6.6.7 Stop Volume Set Check
Use this option to stop the “Check Volume Set” function.
6.7 Physical Drive
Choose this option to select a physical disk from the main menu
and then perform the operations listed below.
6.7.1 Create Pass-Through Disk
To create pass-through disk, move the mouse cursor to the main
menu and click on the “Create Pass-Through” link. The relative
setting function screen appears. A pass-through disk is not con-
trolled by the 6Gb/s SATA RAID controller rmware; it can’t be a
part of a volume set. The disk is available to the operating system

as an individual disk. It is typically used on a system where the
operating system is on a disk not controlled by the RAID rmware. The user can also select the Cache Mode, Tagged Command
Queuing, and SCSI channel/SCSI_ID/SCSI_LUN for this pass-
through disk.
6.7.2 Modify Pass-Through Disk
Use this option to modify the pass-through disk attribute. The
user can modify the Cache Mode, Tagged Command Queuing, and
SCSI Channel/ID/LUN on an existing pass-through disk.
To modify the pass-through drive attribute from the pass-through
drive pool, move the mouse cursor bar and click on the “Modify
Pass-Through” link. The “Select The Pass Through Disk For Modication” screen appears mark the check box for the pass-through
disk from the pass-through drive pool and click on the “Submit”
button to select drive. When the “Enter Pass-Through Disk Attribute” screen appears, modify the drive attribute values, as you
want. After you complete the selection, mark the check box for
“Conrm The Operation” and click on the “Submit” button to com-
plete the selection action.
