ArcHTTP Conguration
3. ArcHTTP Conguration
This chapter describes how to congure the “System Function” of
ArcHTTP. The ArcHTTP proxy utility runs as a service or daemon, and
has it automatically start the proxy for all RAID storages found. This
way the RAID storage can be managed remotely without having to
sign in the server.
Start ArcHTTP– Browser Edition:
1. In Windows, right-click on “Start” menu and choose “Programs”.
Clicking “MRAID” program icon starts the ArcHTTP utility
(From the Start menu, choose Programs > MRAID > ArcHTTP).
2. On a Mac, there is one MARID icon showing on your desktop.
This icon is for you to start up the ArcHTTP utility.
When you click the ArcHTTP, it shows all RAID storages available on
the system and “System Function” on left column of the “ArcHTTP
Congurations” screen. The ArcHTTP has also integrated the email
notication and SNMP function for user to send SNMP traps and e-mail
notications. ArcHTTP conguration setting will store on a le name
“ArcHTTPSrv.conf”.
• General Conguration
Binding IP: Restrict ArcHTTP proxy server to bind only single
interface (If more than one physical network in the server).

Many users require that email notications be sent to the
appropriate administrators when an alert is detected. To set up your
mail servers, click on the the “Mail Conguration” link. The “SMTP
Server Congurations” allows you to dene settings for your mail
server. This setup screen is shown as below:
1. SMTP Server Conguration
SMTP Server IP Address: Enter the SMTP server IP address which
is not McRAID storage manager IP.
Ex: 192.168.0.2.

2. Mail Address Congurations
Sender Name: Enter the sender name that will be shown in the
outgoing mail.
Ex: RaidController_1.
Mail address: Enter the sender email that will be shown in the
outgoing mail, but don’t type IP to replace domain name.
Ex: [email protected].
Account: Enter the valid account if your SMTP mail server
requires authentication.
Password: Enter the valid password if your SMTP mail server
requires authentication.
3. Event Notication Congurations
This step involves setting up of notication rules. Notication
rules instruct ArcHTTP on the notications that should be sent
when certain types of alerts are detected.
MailTo Name: Enter the alert receiver name that will be shown in
the outgoing mail.
Mail Address: Enter the receiver's e-mail address. This is the
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 storage 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 storage
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
43

ArcHTTP Conguration
agent on the host. If SNMP manager requests to query the SNMP
information from RAID storage, please refer the Appendix C "SNMP
Operation & Installation". The “SNMP traps Conguration” menu will
show as following:
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
RAID storage 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_sas.mib le into the traps database. Please refer to Ap-
pendix C of “SNMP Operation & Installation”. The MIBs le resides
at: <CD-ROM>\packages\SNMP_MIBs on the software CD.
44

ArcHTTP Conguration
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 storages to a system. The
ArcHTTP scans the RAID storages on the system and create an
individual RAID storage 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 storage missed on the
system start-up, you can use the "Rescan Device" function. The
"Rescan Device" function is a procedure which forces the ArcHTTP to
rescan the targets to allow a missed RAID storage to be added.
• Collect Support Data
Areca has added the “Collect Support Data” option on the ArcHTTP
utility to download a support le (le name:ctlrxx-xxxxx.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 occurred.”

4. Web Browser-based Conguration
If you need to use a RAID volume from ARC-8050T2 RAID storage
unit, you must rst create a RAID volume by using LCD or McRAID
storage manager. This chapter shows you how to set up RAID volumes
using the McRAID storage manager application on a computer with an
ARC-8050T2 RAID storage.
The McRAID storage manager is rmware-based utility, which is acces-
sible 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 (Safari, IE and Mozilla etc) installed on your
monitor station. It can be accessed through the in-band Thunderbolt
bus or out-of-band onboard LAN port. The in-band-Thunderbolt bus
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.
The rmware-embedded SMTP manager monitors all system events
and user can select either single or multiple user notications to be
sent with “Plain English” e-mails. The rmware-embedded SNMP agent
allows remote to monitor events with no SNMP agent required. Use the
McRAID storage manager to:
• Create RAID set
• Expand RAID set
• Dene volume set
• Add physical drive
• Modify volume set
• Modify RAID level/stripe size
• Dene pass-through disk drives
• Modify system function
• Update rmware
• Designate drives as hot spares

• McRAID Storage Manager Through LAN Port
(Out-of-Band)
ARC-8050T2 RAID storage also offers an alternative out-of-
band method for McRAID storage manager. User can access the
built-in conguration without running the ArcHTTP proxy server
on the host system. The web browser-based McRAID storage
manager is a HTML-based application, which utilizes the browser installed on your remote system. To ensure proper communications between the Thunderbolt RAID storage and McRAID
storage manager, please connect the Thunderbolt RAID storage
LAN port to any LAN switch port.
The RAID storage has embedded the TCP/IP & web browserbased McRAID storage manager in the rmware. User can remote manage the Thunderbolt RAID storage without adding any
user specic software (platform independent) via standard web
browsers directly connected to the 10/100Mbit RJ45 LAN port.
To congure Thunderbolt RAID storage on a remote machine,
you need to know its IP address. The IP address is default
shown on the LCD initial start-up screen. Launch your McRAID
storage manager by entering http://[IP Address] in the web
browser.
4.2 McRAID Main Window
The following login screen is displayed in the browser. This screen

Caution:
Please contact us to make sure if you need to use rescue
function. Improperly usage may cause conguration
corruption.
4.6 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 is the volume set features for the RAID storage.
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 lim-
ited 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.

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.
-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 convert-
ed to “Dynamic Disk”, because 4k sector size is not a standard
format.

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, 256 KB,
512KB or 1M. A larger stripe size produces better read per-
formance, especially if your computer does mostly sequential
reads. However, if you are sure that your computer does ran-
dom reads more often, select a smaller stripe size.

Roaming the stripe size 256K/512K/1M Raid Set to rmware
•
version older than 1.52 will cause data corruption.
• Cache Mode
The RAID storage supports “Write Through” and “Write Back”
cache.
• 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.
• Full Volume Encryption
ARC-8050T2 have featured with controller based hardware
encryption function. Controller based hardware encryption describes the encryption of data occurring at the disk array controller before being sent to the disk drives. Since RAID controller is a natural central point of all data therefore encryption at
this level is inherent and also reduces deployment complexity.
ARC-8050T2 RAID controller has dedicated electronic circuitry
for the cryptographic engine embedded in the ROC and operating at full channel speeds. The hardware encryption does not
impact the performance of ARC-8050T2 RAID controller and can
implement on any kinds of HDD that is transparent to the user,
the OS, and applications.
Encrypting your volume can give your data an extra layer of
protection be yond setting up a controller password. Encryption
will conceal your volume’s data and make accessing the les
almost im possible for anyone who does not know your encryption key. Data saved in the volume will be hidden by Algorithm
developed by Areca Technology. With this scramble process, no
one can see and access into the hidden volume data without
access key. ARC-8050T2 support 128- and 256-bit encryption keys using AES(a key size of 128, or 256 bits), or password (a variable key size). Each encryption key size causes
59

the algorithm to behave slightly differently, so the increasing
key sizes not only offer a larger number of bits with which you
can scramble the data, but also increase the complexity of the
cipher algorithm. ARC-1882 adapters provide ve new key
options in the ‘Full Volume Encryption:”Disable’, “256Bit key,
Password”, “256Bit key, AES”, “128Bit key, Password”, “128Bit
key, AES”. You can generate the new key by CLI utility or API
code function.
This volume encryption function can only work with ARC-1882
series with any kinds of HDD. You can follow below steps to enable the function.
1. Create volume set with “Full Volume Encryption” capability in
the web management.
2. Use CLI “vsf genkey” command or API code to generate key
le.
3. Use “Download Volume Key File” in the web management or
use CLI “vsf dlkey” command to download volume key le
into rmware and unlock the volume.
4. Follow step 3. to unlock volume if volume locked.
• 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 SAS
command tag queuing support for each drive channel. This
function should normally remain “Enabled”. “Disabled” this
function only when using SAS drives that do not support
command tag queuing.
• SCSI Channel/SCSI ID/SCSI Lun
SCSI Channel: The RAID storage 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 a unique SCSI ID number.
A SCSI channel can connect up to 15 devices. The RAID storage
is a large SCSI device. Assign an ID from a list of SCSI IDs.
SCSI LUN: Each SCSI ID can support up to 8 LUNs. Most 6Gb/s
SAS controllers treat each LUN like a SAS disk.

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.

4.6.6 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 on “Checking
After System Idle”).
Note:
Please make sure of the inconsistency source generated by
parity error or bad data block before you click the recovery
method. Otherwise, you will lose the recovery data.

4.8 System Controls
4.8.1 System Cong
To set the RAID system function, move the cursor to the main
menu and click the “System Controls” link. The “Raid System
Function” menu will show all items, and then select the desired
function.
• System Beeper Setting
The “System Beeper Setting” function is used to “Disabled” or
“Enabled” the RAID storage alarm tone generator.
72
• Background Task Priority
The “Background Task Priority” is a relative indication of how
much time the controller devotes to a rebuild operation. The
RAID storage allows the user to choose the rebuild prioity (UltraLow, Low, Medium and High) to balance volume set access
and rebuild tasks appropriately. For high array performance,
specify a “Low” value.
• JBOD/RAID Conguration
JBOD is an acronym for “Just a Bunch Of Disk”. A group of
hard disks in a RAID box are not set up as any type of RAID
conguration. All drives are available to the operating system
as an individual disk. JBOD does not provide data redundancy.
User needs to delete the RAID set, when you want to change
the option from the RAID to the JBOD function.
Page 73
WEB BROWSER-BASED CONFIGURATION
• SATA NCQ Support
The controller supports both SAS and SATA disk drives. The
SATA NCQ allows multiple commands to be outstanding within
a drive at the same time. Drives that support NCQ have an
internal queue where outstanding commands can be dynamically rescheduled or re-ordered, along with the necessary
tracking mechanisms for outstanding and completed portions
of the workload. The RAID storage allows the user to select
the SATA NCQ support: “Enabled” or “Disabled”.
• HDD Read Ahead Cache
Allow Read Ahead (Default: Enabled) — When Enabled,
the drive’s read ahead cache algorithm is used, providing
maximum performance under most circumstances.
• Volume Data Read Ahead
The volume read data ahead parameter species the controller rmware algorithms which process the Read Ahead data
blocks from the disk. The read ahead parameter is normal by
default. To modify the value, you must set it from the command line using the Read Ahead option. The normal option
satises the performance requirements for a typical volume.
The disabled value implies no read ahead. The most efcient
value for the controllers depends on your application. Aggressive read ahead is optimal for sequential access but it degrades random access.
• HDD Queue Depth
This parameter is adjusted the queue depth capacity of NCQ
(SATA HDD) or Tagged Command Queuing (SAS HDD) which
transmits multiple commands to a single target without waiting for the initial command to complete.
• Empty HDD Slot LED
The rmware has added the "Empty HDD Slot LED" option
to setup the fault LED light "ON "or "OFF" when there is no
HDD installed. When each slot has a power LED for the HDD
installed identify, user can set this option to "OFF". Choose
option "ON", the RAID storage will light the fault LED; if no
HDD installed.
73

• Max Command Length
Max Command Length is used to set a "best" IO size for the
RAID storage.
• Auto Activate Incomplete Raid
When some of the disk drives are removed in power off state
or boot up stage, the RAID set state will change to “Incom-
plete State”. But if a user wants to automatically continue to
work while the RAID storage is powered on, the user can set
the “Auto Activate Incomplete Raid” option to enable. The
RAID state will change to “Degraded Mode” while it powers
on.
• Disk Write Cache Mode
User can set the “Disk Write Cache Mode” to Auto, Enabled,
or Disabled. “Enabled” increases speed, “Disabled” increases
reliability.
• Write Same For Initialization
Drives that support the Write Same feature (SCT) can write to
multiple drive sectors at once, improving initialization time. To
take advantage of this feature, all the drives in the unit must
support “Write Same” command. User can set the “SAS And
SATA”, “SAS Only”, “SATA Only or “Disabled” for the controller
initialization.
74
• Hot Plugged Disk For Rebuilding
It denes if the RAID array volume should start rebuilding or
not when detects a disk is inserted/re-inserted during online.
The options are: “Blank Disk Only”, “Always”, and “Disable”.
The default is “Blank Disk Only”.
“Blank Disk Only” – it will trigger the rebuilding if and only if
the inserted disk has not been in the RAID array before, which
has no RAID signature on it. So when a previously removed
disk is self re-inserted, it won’t trigger the degraded RAID array to rebuild, and so that the administrator has a chance to
identify this miss-behaving disk and replace it.
“Always” – it is what it was before. Whenever a disk is inserted/re-inserted whether new or previously existed, it always
Page 75
WEB BROWSER-BASED CONFIGURATION
triggers a rebuilding for the Degraded RAID set/Volume.
“Disable” – it will not trigger rebuilding regardless what sort of
disk plugging in. When “Disable” and/or “Blank Disk Only” is
selected, the re-inserted/previously removed disk will be identied as a disk in a separate RAID set with duplicated RAIDset# and with all the rest of RAID members missing.
• Disk Capacity Truncation Mode
RAID storage uses drive truncation so that drives from differing vendors are more likely to be able to be used as spares for
each other. Drive truncation slightly decreases the usable capacity of a drive that is used in redundant units. The controller
provides three truncation modes in the system conguration:
“Multiples Of 10G”, “Multiples Of 1G”, and “Disabled”.
“Multiples Of 10G” – If you have 120 GB drives from different vendors; chances are that the capacity varies slightly. For
example, one drive might be 123.5 GB, and the other 120
GB. Multiples Of 10G truncates the number under tens. This
makes same capacity for both of these drives so that one
could replace the other.
“Multiples Of 1G” – If you have 123 GB drives from different vendors; chances are that the capacity varies slightly. For
example, one drive might be 123.5 GB, and the other 123.4
GB. Multiples Of 1G truncates the fractional part. This makes
capacity for both of these drives so that one could replace the
other.
“Disabled” – It does not truncate the capacity.
• Smart Option For HDD
This option is used to increase the reliability of SSDs/HDDs by
automatically copying data from a drive with potential to fail
to a designated hot spare or newly inserted drive. The options
are: “Failed The Drive”, “Failed The Drive If Hot Sapre Exist”,
and “Alert Only”. The default is “Alert Only”.
“Failed The Drive” – controllers kill off the SMART fail drive im-
mediately.
75
Page 76
WEB BROWSER-BASED CONFIGURATION
“Failed The Drive If Hot Sapre Exist” – controllers kill off the
SMART fail disk if hot sapre dive is existed.
“Alert” – it will trigger alert when there happens a SMART fail
drive.
• Smart Polling Interval
Besides the scheduled volume check, user can dene the
Smart Pulling Interval to pull the SMART status of each disk.
The default is “on demand”. User can schedule every certain
period of time interval to pull the SMART status of each disk.
When SMART pulling is executed, disk activity will be tempo-
rally halted until the SMART parameter reading is nished.
That is why you don’t want to set the “ Smart Polling Interval”
too frequent. What to use is up to the users to decide based
on their applications and experimental results.
4.8.2 Advanced Conguration
To set the RAID storage advanced system function, move the cur-
sor to the main menu and click the “Advanced Conguration” link.
The “Advanced Conguration” menu will show all items, and then
select the desired function.
76
• TLER Setting
TLER (time-limited error recovery) functions provide support
for WD Caviar RE (RAID) series disks. This is a new option
from WD to support RAID features that were traditionally
missing from standard desktop drives. TLER is a method of
signaling the system RAID controller in the event that an error
recovery process is taking longer than time-out specications
allow. This prevents the RAID controller from dropping the
Page 77
WEB BROWSER-BASED CONFIGURATION
drive from the array during this period. Default value is manufacture setting. You can select between 5, 6 and 7 second.
This feature is used to setup the HDD internal timeout value.
• Timeout Setting
Disk time-out is a registry setting that denes the time that
RAID controller will wait for a hard disk to respond to a command. You can modify the retry value by entering a new value
in the edit box beside this button and then selecting the button. Normally you should not need to modify this value. De-
fault value is 8 seconds: You can select between 3~8 second.
• Number of Retries
This setting determines the number of access that will be attempted before the current command from the RAID controller to the disk drive is aborted. You can modify the retry value
by entering a new value in the edit box beside this button and
then selecting the button. Normally you should not need to
modify this value. There are two selections, either 2 retry or 3
retry.
• Buffer Threshold
This new feature there are 3 options; 25%, 50%, 75%. The
percentage represents how much data should be kept in
resident cache memory (how full cache should get) before
controller starts to ush data onto the hard drives. If the buffer is set for 25%, then all 25% will be cached and is used for
writing data. The remaining cache memory will be used for
reading and other system overhead. Write buffer threshold for
5% is added for video recording. This option will push data to
disk early.
This feature gives controller extra buffer time in case of slow
response from the hard drives within a given time. Conse-
quently, this can prevent a pause in data ow and there will
be continued data access and stream. This feature is very
useful for the video streaming applications where there is high
demand for constant non-stop data ow with no interruption
due to lower performance of specic hardware.
77

WEB BROWSER-BASED CONFIGURATION
• Amount of Read Ahead
Read-Ahead data is buffered in the RAID controller cache,
however, thereby cutting down on the amount of I/O trafc to
the disk. The Amount of Read Ahead denes how many data
of reading at a time, making more efcient use of the RAID
storage. This makes it possible to locate and re-issue the data
without repetitive hard parsing activities.
The Amount of Read Ahead parameter is used to allocate
an amount of memory in the cache memory the frequently
executed queries and return the result set back to the host
without real disk read execution. Default value is Auto: Controller will base on the HDD number to set the amount of Read
Ahead value. You can select between 512KB ~ 16MB.
• Number of AV Stream
RAID controllers are required to have not only the function of
processing ordinary data but also the function of dealing with
AV (audio/video) stream data needing real-time processing.
Since the bus cycle used in RAID controller was designed to
transfer the computer data exactly, it was unsuitable for the
transfer of AV stream needing great band widths. They are
required to do some setting for the handshaking during the
processing of stream data. This setting is an object of trans-
ferring stream data efciently on an existing RAID controller.
Normally you should not need to modify this value. Default
value is 6. You can select between 6~256.
78
To decide how to set AV stream play out parameter, you need
to check the Number of Stream, Amount of Read Ahead, and
Total Cache Memory during runtime. You can try to adjust the
three numbers to get the best performance as your requirement. Number of Stream shows the number of stream added
to the system, Amount of Read Ahead shows the amount
of Read Ahead data taken from the cache without real disk
execution, and Total Cache Memory shows the total available
memory being installed in the RAID controller.
• Optimize AV Recording
AV recording option is for video recording (no time limit), but
if used in normal operation, performance may be degraded.
This new feature there are 4 options; Disabled, Mode1, Mode2
Page 79
WEB BROWSER-BASED CONFIGURATION
and Mode 3. Default value is “Disabled”. Our controller cache
uses LRU method; there have no special memory capacity reserved for read or write. The Mode 1, 2 and 3 are used to de-
ne the command sorting method. The default sorting method
is helpful for normal applications, but not useful for AV ap-
plications, so we have dened three different sorting methods
for these special applications. To decide how to optimize AV
stream recording parameter, you need to adjust the Optimize
AV Recording, and Write Buffer Threshold during runtime.
• Read Performance Margin
The “Read Performance Margin” is for controller to reserve
n% read margin during AV stream recording. It is designed to
eliminate the frame drop and ensure to provide the smooth
and stable performance on the application.
• Write Performance Margin
The “Write Performance Margin” is for controller to reserve n%
write margin AV stream recording. It is designed to eliminate
the frame drop and ensure to provide the smooth and stable
performance on the application.
• Read And Discard Parity Data
This function is used to determine if parity data is to be read
and discarded. It is designed to eliminate the frame drop and
ensure to provide the smooth and stable performance on the
application.
• BIOS Selection
It combines the “Legacy BIOS” and “UEFI BIOS” and “EFI
BIOS” into a single BIOS, and provide BIOS option in the GUI.
In the old days, Areca provided separate BIOS les for each,
and need to manually ash it in. Now ashing BIOS for differ-
ent BIOS type is no longer needed, just make the BIOS selec-
tion in System Controls: Advance Conguration: BIOS Option.
The controller provides three BIOS options.
“Legacy” – for motherboards that are using regular BIOS boot.
“UEFI” – for motherboards (especially Intel’s motherboards)
using UEFI boot
“EFI” – for Intel based MacPro boot
“Disable” – disable controller BIOS at POST (set to 0xFF)
==> If BIOS is to be disabled --> All data are 0xFF

4.8.3 HDD Power Management
Areca has automated the ability to manage HDD power based
on usage patterns. The “HDD Power Management” allows you
to choose a “Stagger Power On Control”, “Low Power Idle”, “Low
RPM” and completely “Spins Down Idle HDD”. It is designed to
reduce power consumption and heat generation on idle drives.
To set the HDD power management function, move the cursor to
the main menu and click the “HDD Power Management” link. The
“HDD Power Management” menu will show all items, and then
select the desired function.
• Stagger Power On Control
In a PC system with only one or two drives, the power can
supply enough power to spin up both drives simultaneously.
But in systems with more than two drives, the startup current
from spinning up the drives all at once can overload the power
supply, causing damage to the power supply, disk drives and
other system components. This damage can be avoided by
allowing the host to stagger the spin-up of the drives. The
SAS/SATA drives have supported the staggered spin-up capabilities to boost reliability. The staggered drive spin-up is
a very useful feature for managing multiple disk drives in a
storage. It gives the host the ability to spin up the disk drives
sequentially or in groups, allowing the drives to come ready at
the optimum time without straining the system power supply.
The staggered drive spin-up in a multiple drive environment
also avoids the extra cost of a power supply designed to meet
short-term startup power demand as well as steady state conditions.
80
With this option it gives the RAID storage the ability to spin
up the disk drives sequentially staggered power up value. The
Page 81
WEB BROWSER-BASED CONFIGURATION
values can be selected from 0.4 to 6 seconds per step which
powers up one drive.
• Time to Hdd Low Power Idle
This option delivers lower power consumption by automatically unloading recording heads during the setting idle time.
The values can be selected “Disabled” or within the range 2 to
7 minutes.
• Time To Hdd Low RPM Mode
This function can automatically spin disks at lower RPM if
there have not been used during the setting idle time. The
values can be selected “Disabled” or within the range 10 to 60
minutes.
• Time To Spin Down Idle HDD
This function can automatically spin down the drive if it hasn’t
been accessed for a certain amount of time. This value is used
by the drive to determine how long to wait (with no disk activity, before turning off the spindle motor to save power). The
values can be selected “Disabled” or within the range 1 to 60
minutes.
• SATA Power Up In Standby
SATA Power Up In Standby (power management 2 mode,
PM2) is a SATA disk drive conguration which prevents the
drive from automatic spinup when power is applied. “Enabled”
option allows the drive to be powered-up into the Standby
power management state to minimize inrush current at
power-up and to allow the controller to sequence the spinup
of devices. It is mainly for server/workstation environments
operating in multiple-drive congurations.
4.8.4 Ethernet Conguration
Use this feature to set the controller Ethernet port conguration.
A customer doesn’t need to create a reserved space on the arrays
before the Ethernet port and HTTP service are working. The rmware-embedded web browser-based RAID manager can access it
from any standard internet browser or from any host computer
either directly connected or via a LAN or WAN with no software or

patches required. To congure the RAID controller Ethernet port,
move the cursor bar to the main menu and click on the “System
Controls” link. The “System Controls” menu will show all items.
Move the cursor bar to the “Ethernet Conguration” item, and
then select the desired function.
• DHCP Function
DHCP (Dynamic Host Conguration Protocol) is a protocol that
lets network administrators manage centrally and automate
the assignment of IP (Internet Protocol) congurations on a
computer network. When using the internet’s set of protocols
(TCP/IP), in order for a computer system to communicate
to another computer system, it needs a unique IP address.
Without DHCP, the IP address must be entered manually at
each computer system. DHCP lets a network administrator
supervise and distribute IP addresses from a central point.
The purpose of DHCP is to provide the automatic (dynamic)
allocation of IP client congurations for a specic time period
(called a lease period) and to eliminate the work necessary to
administer a large IP network.
82
• Local IP address
If you intend to set up your client computers manually (no
DHCP), make sure that the assigned IP address is in the same
range as the default router address and that it is unique to
your private network. However, it is highly recommend to use
DHCP if that option is available on your network. An IP address allocation scheme will reduce the time it takes to set-up
client computers and eliminate the possibilities of administra-
tive errors and duplicate addresses. To manually congure
the IP address of the controller, move the cursor bar to Local
IP address item, then reassign the static IP address of the
controller.
Page 83
WEB BROWSER-BASED CONFIGURATION
• Gateway IP address
A gateway is a node (a router) on a TCP/IP network that
serves as an access point to another network. A default gateway is the node on the computer network that the network
software uses when an IP address does not match any other
routes in the routing table.
• Subnet Mask
A Subnet mask is a 32-bit number that masks an IP address,
and divides the IP address into network address and host address.
• HTTP Port Number
To manually congure the “HTTP Port Number” of the controller, move the cursor bar to “HTTP Port Number” item, then
reassign the default “HTTP Port Number” of the controller.
• Telnet Port Number
To manually congure the “Telnet Port Number” of the controller, move the cursor bar to “Telnet Port Number” item, then
reassign the default “Telnet Port Number” of the controller.
• SMTP Port Number
To manually congure the “SMTP Port Number” of the controller, Move the cursor bar to “SMTP Port Number” item, then
reassign the default “SMTP Port Number” of the controller.
Note:
If you congure the HTTP Port Number to 0, the HTTP
console will be closed.
4.8.5 Alert By Mail Conguration
To congure the RAID storage e-mail function, move the cursor
bar to the main menu and click on the “System Controls” link.
The “System Controls” menu will show all items. Move the cursor bar to the “Alert By Mail Conguration” item, and then select
the desired function. This function can only be set via web-based
conguration.

The rmware contains a SMTP manager monitoring all system
events. Single or multiple user notications can be sent via “Plain
English” e-mails with no software required. (Please refer to SMTP
Sever Conguration, Mail Address Conguration and Event Notication Conguration on chapter 3 “ArcHTTP Conguration” ).
4.8.6 SNMP Conguration
Please refer to Appendix C of SNMP Operation & Installation.
4.8.7 NTP Conguration
The Network Time Protocol (NTP) is used to synchronize the time
of a computer client or server to another server or reference time
source, such as a radio or satellite receiver or modem. It provides
accuracies typically within a millisecond on LANs and up to a few
tens of milliseconds on WANs relative to Coordinated Universal
Time (UTC) via a Global Positioning Service (GPS) receiver, for
example:
84
Page 85
WEB BROWSER-BASED CONFIGURATION
Note:
NTP feature works through onboard Ethernet port. So you
must make sure that you have connected onboard Ethernet
port.
• NTP Sever Address
The most important factor in providing accurate, reliable time
is the selection of NTP servers to be used in the conguration
le. Typical NTP congurations utilize multiple redundant serv-
ers and diverse network paths in order to achieve high accura-
cy and reliability. Our NTP conguration supports two existing
public NTP synchronization subnets.
• Time Zone
Time Zone conveniently runs in the system tray and allows
you to easily view the date and time in various locations
around the world. You can also quickly and easily add your
own personal locations to customize time zone the way you
want.
• Automatic Daylight Saving
Automatic Daylight Saving will normally attempt to automatically adjust the system clock for daylight saving changes
based on the computer time zone. This tweak allows you to
disable the automatic adjustment.

Upgrading Flash ROM Update Process
A-1 Overview
Since the ARC-8050T2 Thunderbolt RAID storage features ash
ROM rmware, it is not necessary to change the hardware ash
chip in order to upgrade the RAID rmware. The user can simply
re-program the old rmware through the in-Band Thunderbolt port
or out-of-band LAN port McRAID storage manager. New releases of
the rmware are available in the form of a DOS le on the shipped
CD or Areca website. The les available at the FTP site for each
model contain the following les in each version:
ARC8050NNNN.BIN: Software binary code (“NNNN” refers to the
software code type)
ARC8050BIOS.BIN:→ PCIe 2.0 BIOS for system board using
ARC8050BOOT.BIN:→ RAID controller hardware initialization
ARC8050FIRM.BIN:→ RAID kernel program
ARC8050MBR0.BIN:→ Master Boot Record for supporting Dual
Flash Image in the ARC-8050T2 6Gb/s SAS RAID storage
README.TXT contains the history information of the software code
change in the main directory. Read this le rst to make sure you
are upgrading to the proper binary le. Select the right le for the
upgrade. Normally, user upgrades ARC8050FIRM.BIN for RAID
function. All these les in the rmware package are a part of the
rmware. You should update all les in the package, no special
update order needed. New rmware works after a system restart
not instant available, so you can update all les before restart the
system. The controller rmware is independent of the array; update rmware does not touch anything you stored in the array.
Note:
ARC-8050T2 Thunderbolt 2 RAID storage uses the same
rmware package of ARC-1882 series RAID adapters. Please
update all binary code (BIOS, BOOT, FIRM and MBR0) before
you reboot system. Otherwise, a mixed rmware package may
hang the controller.

Appendix C
SNMP Operation & Installation
C-1 Overview
McRAID storage manager includes a rmware-embedded Simple
Network Management Protocol (SNMP) agent and SNMP Extension
Agent for the Areca RAID controller. An SNMP-based management
application (also known as an SNMP manager) can monitor the disk
array. An example of a SNMP management application is HewlettPackard’s Open View, Net-SNMP or SNMPc. The SNMP extension
agent can be used to augment the Areca RAID controller if you are
already running an SNMP management application at your site.
C-2 SNMP Denition
SNMP, an IP-based protocol, has a set of commands for getting the
status of target devices. The SNMP management platform is called
the SNMP manager, and the managed devices have the SNMP
agent loaded. Management data is organized in a hierarchical data
structure called the Management Information Base (MIB). These
MIBs are dened and sanctioned by various industry associations.
Each type of device on your network has its own specic MIB le.
The MIB le denes the device as a set of managed objects — val-
ues that can be read or changed by the SNMP manager. The MIB
le enables the SNMP manager to interpret trap messages from
devices. To make sense out of a trap that’s sent by a device, the
SNMP manager needs to have access to the MIB that describes
the format and content of the possible traps that the device can
send. The objective is for all vendors to create products in compliance with these MIBs so that inter-vendor interoperability can be
achieved. To be available for the SNMP manager, a command adds
the MIB le for each of devices to the MIB database. This enables
the devices to be managed via the SNMP manager.
The following gure illustrates the various components of an SNMP-
based management architecture.

C-3 SNMP Installation
Perform the following steps to install the Areca RAID controller SNMP function into the SNMP manager. The installation of the
SNMP manager is accomplished in several phases:
Step 1.Installing the SNMP manager software on the client
Installing the SNMP manager software on the client. This installation process is well-covered in the User’s Guide of your SNMP
manager application.
Step 2. Compiling the MIB description le with the management
Placing a copy of the RAID controller’s MIBs le in a directory which
is accessible to the management application and compile the MIB
description le with the SNMP management application database.
Before the manager application accesses the Areca RAID controller,
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 manager application. Ensure the compilation
process successfully integrates the contents of the areca_sas.mib
le into the traps database. The MIBs le resides at: <CD-ROM>\
packages\SNMP_MIBs on the software CD or download from http://
www.areca.com.tw.
98
Page 99
APPENDIX
Each RAID storage needs to have its own MIBs le. Areca provides
4 RAID storage MIBs le for users. User can request it if more con-
trollers install on one system.
Note:
1. The MIB compiler may be not installed by default with SNMP
manager.
2. Some SNMP managers have unique rule on the format of
MIB les, you may need to refer the error message to
modify the mib le to be able to met the software
requirement.
Step 3. SNMP Service Method
With Areca series RAID controllers, there are 2 service methods to
get SNMP: in-band Thunderbolt port and onboard NIC.
1. Service Method-1: Using in-band Thunderbolt port (ArcHTTP
proxy server)
Pay attention to these:
• Do not check mark the option: “SNMP Through PCI”.
• Make sure you have the latest driver and ArcHTTP, from this
URL http://www.areca.com.tw/support/
• ArcHTTP supports sending “traps” only, do not support the
“get” command.
2. Service Method-2: Using onboard LAN port.
Pay attention to these:
• Do not check mark the option: “SNMP Through PCI”.
• Do need to ll out the “SNMP Trap Cong”.
C-3-1 Using ArcHTTP
The HTTP management software (ArcHTTP) runs as a service or
daemon, and has it automatically start the proxy for all controllers found. This way the controller can be managed remotely
without having to sign in the server. The ArcHTTP has also integrated the ability of sending SNMP trap. Please reference the
manual Chapter 3 “ArcHTTP Conguration” section to install and
setup its conguration.
99
Page 100
APPENDIX
To enable the 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 utility. To enable the RAID
controller SNMP traps sending function, congure the “SNMP
Traps Conguration” options on the "ArcHTTP Congurations".
The ArcHTTP proxy only provides one direction to send the
trap to the SNMP manager without needing to install the SNMP
extension agent on the host. For detailed information on using
ArcHTTP proxy server utility to send the SNMP traps, please
see "SNMP Traps Conguration" section on chapter 3 "ArcHTTP
Conguration".
If SNMP manager requests to query the SNMP information from
RAID controller, please refer the C-3-2 section "Using Onboard
NIC”.
C-3-2 Using Onboard NIC Installation
With the built-in LAN port, you can add SNMP function onto your
the RAID storage. You can use the browser-based manager to
setup the rmware-based SNMP conguration. To launch the
browser-based RAID controller SNMP function, click on the “Sys-
tem Controls” link. The “System Controls” menu will show available items. Select the “SNMP Conguration” item. The following screen is the rmware-embedded SNMP conguration setup
screen using browser-based manager:
