2.4.2 Mac Users 2.4.2.1 Install Areca driver for Mac
On November 10, 2020, Apple revealed new Mac hardware with the revolutionary Apple Silicon M1 processors. Since external boot via 3rd party drivers is not allowed on Apple Silicon based Macs, the default Areca driver doesn’t work on new M1 Mac, only for Intel-based Macs. The macOS 11 had not been integrated any universal KEXTs into macOS, which means that users need to install universal KEXT to support Areca Thunderbolt devices on Apple Silicon. Areca universal KEXT’s on Apple Silicon can be installed in /Library/ Extensions/, even if Areca RAID storage x86-only versions persists on the system in /System/Library/Extensions/. In order to use 3rd party kernel extensions on Apple Silicon Macs, users must enable system extensions by changing their Mac’s Security Policy to Reduced Security and allow user management of kernel extensions from identified developers.

If your mac version is below 11.0, you can skip this step Step 1. Start up your computer in macOS Recovery (1-1). Choose “Shut Down”. (1-2). Press and hold the power button on your Mac until you

ArcHTTP Configuration
2. Mail Address Configurations 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 Notification Configurations This step involves setting up of notification rules. Notification rules instruct ArcHTTP on the notifications 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 address you want the e-mail alerts sent to. Ex: [email protected].
According to your requirement, set the corresponding event level: Disable Event Notification: No event notification will be sent. Urgent Error Notification: Send only urgent events. Serious Error Notification: Send urgent and serious events. Warning Error Notification: Send urgent, serious and warning events. Information Notification: Send all events. Notification For No Event: Notify user if no event occurs within 24 hours.
· SNMP Traps Configuration
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 Configuration” link. The ArcHTTP proxy only provide one direction to send the trap to the SNMP manager without needing to install the SNMP extension

ArcHTTP Configuration
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 Configuration” menu will show as following:
When you open the SNMP traps configuration page, you will see the following settings: 1. SNMP Trap Configurations
Enter the SNMP trap IP address. 2. SNMP System Configurations
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 field. 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 Notification Configurations 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-specific 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 file into the traps database. Please refer to Ap-
pendix C of “SNMP Operation & Installation”. The MIBs file resides
at: packagesSNMP_MIBs on the software CD.
62

ArcHTTP Configuration
Note:
Event Notification Table refer to Appendix D. After you confirm and submit configurations, you can use “Generate Test Event” feature to make sure these settings are correct. · Rescan Device Configuration 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 Configurations” 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 file (file name:ctlrxx-xxxxx.log) with all necessary information (system information, configuration, disk information, eventlog). The “Collect Support Data” function will be automatically started when ERROR or SERIOUS event occurred.”

WEB BROWSER-BASED CONFIGURATION 4. Web Browser-based Configuration
If you need to use a RAID volume from ARC-8050T3U RAID storage unit, you must first 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-8050T3U RAID storage. The McRAID storage manager is firmware-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 (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 firmware-embedded web browser-based McRAID storage manager allows local or remote to access it from any standard internet browser. The firmware-embedded SMTP manager monitors all system events and user can select either single or multiple user notifications to be sent with “Plain English” e-mails. The firmware-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 · Define volume set · Add physical drive · Modify volume set · Modify RAID level/stripe size · Define pass-through disk drives · Modify system function · Update firmware · Designate drives as hot spares

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 specified 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.
See Areca website ftp://ftp.areca.com.tw/RaidCards/Documents/Manual_Spec/ Over2TB_050721.ZIP file for details.
4.6.1 Create Volume Set (0/1/10/3/5/6)
To create volume set from RAID set storage, 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 and then click on the “Submit” button.
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.
75

WEB BROWSER-BASED CONFIGURATION
· Volume Name The default volume name will always appear as “ARC-8050T3UVOL”. 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. There are two circumstances when you choose RAID level 1 function: RAID 1-Simple Mirroring is also known as “two disk mirror”; If your RAID set has two disks, data written on one disk drive is simultaneously written to another disk drive. RAID 1-Multi Mirroring is also known as “triple disk mirror”; If your RAID set has three disks, data written on one disk drive is simultaneously written to another two disk drives.
· Capacity The maximum volume size is the default initial setting. Enter the appropriate volume size to fit your application.
· Greater Two TB Volume Support Controller uses the “Greater Two TB Volume Support” sub-menu to set the volume capacity and sector size. Greater Two TB Volume Support option: “No”, “64bit LBA” and “Use 4K Block”.
76

WEB BROWSER-BASED CONFIGURATION
-No When this option is enabled, it keeps the volume size with max. 2TB limitation. For any hard disk drives working in the 4K native mode in the Raid set, the volume set directly sets and exposes 4KB sector size to the operating system.
-64bit LBA This option uses 16 bytes CDB instead of 10 bytes. The maximum volume capacity is up to 512TB. For any hard disk drives working in the 4K native mode in the Raid set, the volume set directly sets and exposes 4KB sector size to the operating system. This option works on different OS which supports 16 bytes CDB.
-Use 4K Block This option uses 16 bytes CDB and changes the sector size from default 512 bytes to 4k bytes. Windows XP only supports maximum volume capacity is up to 16TB.
· Initialization Mode This option is used to define “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 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.
77

WEB BROWSER-BASED CONFIGURATION
Note: · RAID level 3 can’t modify the cache stripe size. · Roaming the stripe size 256K/512K/1M Raid Set to firmware
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-8050T3U 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-8050T3U 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-8050T3U 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 beyond setting up a controller password. Encryption will conceal your volume’s data and make accessing the files almost impossible 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-8050T3U 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
78

WEB BROWSER-BASED CONFIGURATION
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 five 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
file. 3. Use “Download Volume Key File” in the web management or
use CLI “vsf dlkey” command to download volume key file into firmware 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.

4.6.6 Schedule Volume Check
A volume check is a process that verifies 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 verifies 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.

The Areca RAID controllers support Self-Encrypting Disks (SED) for protection of data against loss or theft of SEDs. Protection is achieved by the SED hard drive that automatically and continuously encrypts the data on the drive without any user interaction. There is one SED key per controller. You can manage the SED key under McRAID manager. Local SED key management in the controller firmware is designed to protect data from security breaches with minimal cost and complexity. The key can be escrowed in to a file using McRAID manager. Creating and managing SED key is an important part of the cryptographic process. The key must be kept secret from anyone who should not decrypt your data. This section describes how to generate and manage keys.
4.7.4.1 SED Key Management-Creation
There is one SED key per controller which stores in the controller flash memory. Areca provides both automatically or password methods to generate a key.

It sets a normal working disk as “failed” so that users can test some of the features and functions.
4.8.7 Activate Failed Disk
It forces the current “failed” disk in the system to be back online. “Activate Failed Disk” function has no effect on the removed disks, because a “removed” disk does not give the controller a chance to mark it as “failure”. 96

WEB BROWSER-BASED CONFIGURATION
Followings are considered as “Removed-Disk”: 1. Manually removed by user. 2. Losing PHY connection due to bad connector, cable, backplane. 3. Losing PHY connection due to disk fail. Basically, in the eyes of the controller, the disk suddenly disappears due to whatever reason.
4.8.8 Identify Enclosure
To prevent removing the wrong enclosure, the selected Areca expander enclosure all disks fault LED indicator will light for physically locating the selected enclosure when the “Identify Enclosure” is selected. This function will also light the enclosure LED indicator, if it is existed.
4.8.9 Identify Drive
To prevent removing the wrong drive, the selected disk fault LED indicator will light for physically locating the selected disk when the “Identify Selected Device” is selected.

WEB BROWSER-BASED CONFIGURATION 4.9 System Controls
4.9.1 System Config
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.
· 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 Configuration 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 configuration. 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.

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 specifies the controller firmware 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 satisfies the performance requirements for a typical volume. The disabled value implies no read ahead. The most efficient 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 firmware 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.

WEB BROWSER-BASED CONFIGURATION
· 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 “Incomplete 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.
· Hot Plugged Disk For Rebuilding It defines 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
100

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 identified 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 configuration: “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 immediately.
101

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 define 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 temporally halted until the SMART parameter reading is finished. 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.
4.9.2 Advanced Configuration
To set the RAID storage advanced system function, move the cursor to the main menu and click the “Advanced Configuration” link. The “Advanced Configuration” menu will show all items, and then select the desired function.

WEB BROWSER-BASED CONFIGURATION
· 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 specifications allow. This prevents the RAID controller from dropping the 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 defines 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. Default 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 flush 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 incoming write 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 flow 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 flow with no interruption due to lower performance of specific hardware.
· Read Ahead Count The Read Ahead count is used to define how many times (1, 2, 3, ….., 10) of the “Amount of Read Ahead X Read Ahead Requests” data reading at a time. Default value is Auto: Controller will base on the HDD number to set the amount of Read Ahead Count value. You can select between Auto, 1, 2, ….. or 10.
· Read Ahead Requests The Read Ahead Requests is used to define how many times (1, 2, 3) of the “Amount of Read Ahead ” data reading at a time. Default value is 1. You can select between 1, 2, or 3.
· Amount of Read Ahead Read-Ahead data is buffered in the RAID controller cache, however, thereby cutting down on the amount of I/O traffic to the disk. The Amount of Read Ahead defines how many data of reading at a time, making more efficient 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 transferring stream data efficiently on an existing RAID controller. Normally you should not need to modify this value. Default value is 6. You can select between 6~256.
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 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 define the command sorting method. The default sorting method is helpful for normal applications, but not useful for AV applications, so we have defined 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.

· 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 files for each, and need to manually flash it in. Now flashing BIOS for different BIOS type is no longer needed, just make the BIOS selection in System Controls: Advance Configuration: BIOS Option. The controller provides three BIOS options. 107
WEB BROWSER-BASED CONFIGURATION
“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
· Host Command Queue Mode This option is used to solve the the problem with reads stalling that causes by out of order command completion. Choose the “Host Command Queue Mode” option=”Ordered” on the “Advanced Configuration” if you want similar read/write throughputs. There the read and write get the same priority as they are scheduled and the reads are not pushed back.
· Save SED Key In Controller If enable –> disable, clear SED Key saved in setup If disable –> enable, if key exists, save to setup
If enable—>disable, the key will not remain in the flash. So that next time power up again, it will need to input the key from the CLI or McRAID manager. You can also import the key file (Import Security Key) or key-in the password (Enter SED Key By Password) from the GUI interface.
· Fail Disk For Reading Error This option is available to improve the fail disk function if the disk has too many reading errors. This function is the option that RAID controller will kill off the HDD for reading error account setting value.
– 3 errors in 70 seconds: this option also includes 4 errors in 100 seconds, 5 errors in 120 seconds
– 6 errors in 2 minutes: this option also includes 8 errors in 180 seconds, 10 errors in 240 seconds
– 9 errors in 3 minutes: this option also includes 12 errors in 270 seconds, 15 errors in 360 seconds

· Thunderbolt Receive Sleep Request To the user, the system appears to be either on or off. There are no other detectable states. However, the system supports multiple power states that correspond to the power states defined in the Advanced Configuration and Power Interface (ACPI) specification. ARC- 8050T3U RAID storage contains power On/Off controls on the controller. The Thunderbolt Receive Sleep Request function is used to define the ARC-8050T3U power state based on the host computer power state. The Thunderbolt Receive Sleep Request options are as follows:
– Turn Power Off (original mode) The power On/Off controls can turn ARC- 8050T3U power in unison with the host computer power state.
– Keep Power On for 10/20/40/60/90/120 minutes or always on The ARC-8050T3U keeps on the time frame of setting when host computer enters sleep state (ACPI S1-S4 state). The ARC-8050T3U automatically turns off itself when it receives ACPI S5 state or is disconnected from host computer. Otherwise you still need to power it off by press Reset Button on the RAID storage.
<1> when sleep request, raid power is kept on, background process is also kept on –> if cable unplugged or forced power off ==> stop background process, flush disk cache and power off –> if host turns on, raid leaves this state and proceed to normal state <2> if normal shutdown, force power off, cable unplug –> normal power off: stop background process, flush disk cache and power off 109
