INTRODUCTION
1. Introduction
This section presents a brief overview of the SATA RAID Series controller, ARC-1110/1110ML/1120/1120ML/1130/1130ML/1160/ 1160ML/1170 (4/8/12/16/24-port PCI-X SATA RAID Controllers) and ARC-1210/1220/1230/1230/1231ML/1260/1261ML/1280/1280ML (4/8/12/16/24-port PCI-Express SATA RAID Controllers).
1.1 Overview
The ARC-11xx and ARC-12xx Series of high-performance Serial ATA RAID controllers support a maximum of 4, 8, 12, 16, or 24 SATA II peripheral devices (depending on model) on a single controller. The ARC-11xx series for the PCI-X bus and the ARC-12xx Series for the PCI-Express bus. When properly congured, these SATA controllers provide non-stop service with a high degree of fault tolerance through the use of RAID technology and can also provide advanced array management features.
The 4 and 8 port SATA RAID controllers are low-prole PCI cards, ideal for 1U and 2U rack-mount systems. These controllers utilize the same RAID kernel that has been eld-proven in Areca existing external RAID controllers, allowing Areca to quickly bring stable and reliable RAID controllers to the market.
Unparalleled Performance
The SATA RAID controllers provide reliable data protection for desktops, workstations, and servers. These cards set the stan­dard with enhancements that include a high-performance Intel I/O Processor, a new memory architecture, and a high performance PCI bus interconnection. The 8/12/16/24-port controllers with the RAID 6 engine built-in can offer extreme-availability RAID 6 functionality. This engine can concurrently compute two parity blocks with per­formance very similar to RAID 5. The controllers by default support 256MB of ECC SDRAM memory. The 12/16/24 port controllers sup­port one DDR333 SODIMM socket that allows for upgrading up to 1GB of memory. The 12/16/24 port controllers support one DDR2­533 DIMM socket that allows for upgrading up to 2GB of memory. The controllers use Marvell 4/8 channel SATA PCI-X controller

INTRODUCTION
chips, which can simultaneously communicate with the I/O proces­sor and read or write data on multiple drives.
Unsurpassed Data Availability
As storage capacity requirements continue to rapidly increase, us­ers require greater levels of disk drive fault tolerance, which can be implemented without doubling the investment in disk drives. RAID 1 (mirroring) provides high fault tolerance. However, half of the drive capacity of the array is lost to mirroring, making it too costly for most users to implement on large volume sets due to dobuling the number of drives required. Users want the protection of RAID 1 or better with an implementation cost comparable to RAID 5. RAID 6 can offer fault tolerance greater than RAID 1 or RAID 5 but only consumes the capacity of 2 disk drives for distributed parity data. The 8/12/16/24-port RAID controllers provide RAID 6 functionality to meet these demanding requirements.
The SATA RAID controllers also provide RAID levels 0, 1, 1E, 3, 5 or JBOD congurations. Its high data availability and protection is derived from the following capabilities: Online RAID Capacity Ex­pansion, Array Roaming, Online RAID Level / Stripe Size Migration, Dynamic Volume Set Expansion, Global Online Spare, Automatic Drive Failure Detection, Automatic Failed Drive Rebuilding, Disk Hot-Swap, Online Background Rebuilding and Instant Availabil­ity/Background Initialization. During the controller rmware ash upgrade process, it is possible that an error results in corruption of the controller rmware. This could result in the device becoming non-functional. However, with our Redundant Flash image feature, the controller will revert back to the last known version of rmware and continue operating. This reduces the risk of system failure due to rmware crashes.
Easy RAID Management
The SATA RAID controller utilizes built-in rmware with an embed­ded terminal emulation that can access via hot key at BIOS boot­up screen. This pre-boot manager utility can be used to simplify the setup and management of the RAID controller. The controller rmware also contains a ArcHttp browser-based program that can be accessed through the ArcHttp proxy server function in Windows,

1.3 RAID Concept
1.3.1 RAID Set
A RAID set is a group of disks connected to a RAID controller. A RAID set contains one or more volume sets. The RAID set itself does not dene the RAID level (0, 1, 1E, 3, 5, 6, etc); the RAID level is dened within each volume set. Therefore, volume sets are contained within RAID sets and RAID Level is dened within the volume set. If physical disks of different capacities are grouped together in a RAID set, then the capacity of the smallest disk will become the effective capacity of all the disks in the RAID set.
1.3.2 Volume Set
Each volume set is seen by the host system as a single logical de­vice (in other words, a single large virtual hard disk). A volume set will use a specic RAID level, which will require one or more physi­cal disks (depending on the RAID level used). RAID level refers to the level of performance and data protection of a volume set. The capacity of a volume set can consume all or a portion of the avail­able disk capacity in a RAID set. Multiple volume sets can exist in a RAID set.
For the SATA RAID controller, a volume set must be created either on an existing RAID set or on a group of available individual disks (disks that are about to become part of a RAID set). If there are pre-existing RAID sets with available capacity and enough disks for the desired RAID level, then the volume set can be created in the existing RAID set of the user’s choice.

INTRODUCTION
In the illustration, volume 1 can be assigned a RAID level 5 of operation while volume 0 might be assigned a RAID level 1E of operation. Alterantively, the free space can be used to create vol­ume 2, which could then be set to use RAID level 5.
1.3.3 Ease of Use Features
1.3.3.1 Foreground Availability/Background Initial­ization
RAID 0 and RAID 1 volume sets can be used immediately af­ter creation because they do not create parity data. However, RAID 3, 5 and 6 volume sets must be initialized to generate parity information. In Backgorund Initialization, the initializa­tion proceeds as a background task, and the volume set is fully accessible for system reads and writes. The operating system can instantly access the newly created arrays without requir­ing a reboot and without waiting for initialization to complete. Furthermore, the volume set is protected against disk failures while initialing. If using Foreground Initialization, the initializa­tion process must be completed before the volume set is ready for system accesses.

1.3.3.2 Array Roaming
The SATA RAID controllers store RAID conguration information on the disk drives. The controller therefore protect the congu­ration settings in the event of controller failure. Array roaming allows the administrators the ability to move a completele RAID set to another system without losing RAID conguration infor-
Page 17
INTRODUCTION
mation or data on that RAID set. Therefore, if a server fails, the RAID set disk drives can be moved to another server with an
Areca RAID controller and the disks can be inserted in any order.
1.3.3.3 Online Capacity Expansion
Online Capacity Expansion makes it possible to add one or more physical drives to a volume set without interrupting server op­eration, eliminating the need to backup and restore after recon­guration of the RAID set. When disks are added to a RAID set, unused capacity is added to the end of the RAID set. Then, data on the existing volume sets (residing on the newly expanded RAID set) is redistributed evenly across all the disks. A contigu­ous block of unused capacity is made available on the RAID set. The unused capacity can be used to create additional volume sets.
A disk, to be added to a RAID set, must be in normal mode (not failed), free (not spare, in a RAID set, or passed through to host) and must have at least the same capacity as the smallest disk capacity already in the RAID set.
Capacity expansion is only permitted to proceed if all volumes on the RAID set are in the normal status. During the expansion process, the volume sets being expanded can be accessed by the host system. In addition, the volume sets with RAID level 1, 1E, 3, 5 or 6 are protected against data loss in the event of disk failure(s). In the case of disk failure, the volume set transitions from “migrating” state to “migrating+degraded“ state. When the expansion is completed, the volume set would then transition to “degraded” mode. If a global hot spare is present, then it further transitions to the “rebuilding” state.

INTRODUCTION
The expansion process is illustrated as following gure.
The SATA RAID controller redistributes the original volume set over the original and newly added disks, using the same fault­tolerance conguration. The unused capacity on the expand RAID set can then be used to create an additional volume set, with a different fault tolerance setting (if required by the user.)

INTRODUCTION
1.3.3.4 Online RAID Level and Stripe Size Migration
For those who wish to later upgrade to any RAID capabilities, a system with Areca online RAID level/stripe size migration allows a simplied upgrade to any supported RAID level without having to reinstall the operating system.
The SATA RAID controllers can migrate both the RAID level and stripe size of an existing volume set, while the server is on­line and the volume set is in use. Online RAID level/stripe size migration can prove helpful during performance tuning activities as well as when additional physical disks are added to the SATA RAID controller. For example, in a system using two drives in RAID level 1, it is possible to add a single drive and add capac­ity and retain fault tolerance. (Normally, expanding a RAID level 1 array would require the addition of two disks). A third disk can be added to the existing RAID logical drive and the volume set can then be migrated from RAID level 1 to 5. The result would be parity fault tolerance and double the available capacity without taking the system down. A forth disk could be added to migrate to RAID level 6. It is only possible to migrate to a higher RAID level by adding a disk; disks in an existing array can’t be recongured for a higher RAID level without adding a disk.
Online migration is only permitted to begin, It all volumes to be migrated are in the normal mode. During the migration process, the volume sets being migrated are accessed by the host sys­tem. In addition, the volume sets with RAID level 1, 1E, 3, 5 or 6 are protected against data loss in the event of disk failure(s). In the case of disk failure, the volume set transitions from mi­grating state to (migrating+degraded) state. When the migra­tion is completed, the volume set transitions to degraded mode. If a global hot spare is present, then it further transitions to rebuilding state.
1.3.3.5 Online Volume Expansion
Performing a volume expansion on the controller is the process of growing only the size of the lastest volume. A more exible option is for the array to concatenate an additional drive into the RAID set and then expand the volumes on the y. This happens
19
Page 20
INTRODUCTION
transparently while the volumes are online, but, at the end of the process, the operating system will detect free space at after the existing volume.
Windows, NetWare and other advanced operating systems sup­port volume expansion, which enables you to incorporate the additional free space within the volume into the operating sys­tem partition. The operating system partition is extended to incorporate the free space so it can be used by the operating system without creating a new operating system partition.
You can use the Diskpart.exe command line utility, included with Windows Server 2003 or the Windows 2000 Resource Kit, to ex­tend an existing partition into free space in the dynamic disk.
Third-party software vendors have created utilities that can be used to repartition disks without data loss. Most of these utilities work ofine. Partition Magic is one such utility.
1.4 High availability
1.4.1 Global Hot Spares
A Global Hot Spare is an unused online available drive, which is ready for replacing the failure disk. The Global Hot Spare is one of the most important features that SATA RAID controllers provide to deliver a high degree of fault-tolerance. A Global Hot Spare is a spare physical drive that has been marked as a global hot spare and therefore is not a member of any RAID set. If a disk drive used in a volume set fails, then the Global Hot Spare will automatically take its place and he data previously located on the failed drive is reconstructed on the Global Hot Spare.
For this feature to work properly, the global hot spare must have at least the same capacity as the drive it replaces. Global Hot Spares only work with RAID level 1, 1E, 3, 5, or 6 volume set. You can congure up to three global hot spares with ARC-11xx/ 12xx.
The Create Hot Spare option gives you the ability to dene a
20
Page 21
INTRODUCTION
global hot spare disk drive. To effectively use the global hot spare feature, you must always maintain at least one drive that is marked as a global spare.
Important:
The hot spare must have at least the same capacity as the drive it replaces.
1.4.2 Hot-Swap Disk Drive Support
The SATA controller chip includes a protection circuit that supports the replacement of SATA hard disk drives without having to shut down or reboot the system. A removable hard drive tray can de­liver “hot swappable” fault-tolerant RAID solutions at prices much less than the cost of conventional SCSI hard disk RAID control­lers. This feature provides advanced fault tolerant RAID protection and “online” drive replacement.
1.4.3 Auto Declare Hot-Spare
If a disk drive is brought online into a system operating in de­graded mode, The SATA RAID controllers will automatically de­clare the new disk as a spare and begin rebuilding the degraded volume. The Auto Declare Hot-Spare function requires that the smallest drive contained within the volume set in which the failure occurred.
In the normal status, the newly installed drive will be recongured an online free disk. But, the newly-installed drive is automatically assigned as a hot spare if any hot spare disk was used to rebuild and without new installed drive replaced it. In this condition, the Auto Declare Hot-Spare status will disappeared if the RAID sub­system has since powered off/on.
The Hot-Swap function can be used to rebuild disk drives in arrays with data redundancy such as RAID level 1, 1E, 3, 5, and 6.
21
Page 22
INTRODUCTION
1.4.4 Auto Rebuilding
If a hot spare is available, the rebuild starts automatically when a drive fails. The SATA RAID controllers automatically and trans­parently rebuild failed drives in the background at user-denable rebuild rates.
If a hot spare is not available, the failed disk drive must be re­placed with a new disk drive so that the data on the failed drive can be automatically rebuilt and so that fault tolerance can be maintained.
The SATA RAID controllers will automatically restart the system and the rebuild process if the system is shut down or powered off abnormally during a reconstruction procedure condition.
When a disk is hot swapped, although the system is functionally operational, the system may no longer be fault tolerant. Fault tolerance will be lost until the removed drive is replaced and the rebuild operation is completed.
During the automatic rebuild process, system activity will contin­ue as normal, however, the system performance and fault toler­ance will be affected.
1.4.5 Adjustable Rebuild Priority
Rebuilding a degraded volume incurs a load on the RAID sub­system. The SATA RAID controllers allow the user to select the rebuild priority to balance volume access and rebuild tasks ap­propriately. The Background Task Priority is a relative indication of how much time the controller devotes to a background operation, such as rebuilding or migrating.
The SATA RAID controller allows user to choose the task priority (Ultra Low (5%), Low (20%), Medium (50%), High (80%)) to bal­ance volume set access and background tasks appropriately. For high array performance, specify an Ultra Low value. Like volume initialization, after a volume rebuilds, it does not require a system reboot.

INTRODUCTION
1.5 High Reliability
1.5.1 Hard Drive Failure Prediction
In an effort to help users avoid data loss, disk manufacturers are now incorporating logic into their drives that acts as an "early warning system" for pending drive problems. This system is called S.M.A.R.T. The disk integrated controller works with multiple sensors to monitor various aspects of the drive's performance, determines from this information if the drive is behaving normally or not, and makes available status information to RAID controller rmware that probes the drive and look at it. The SMART can often predict a problem before failure occurs. The controllers will recognize a SMART error code and notify the administer of an impending hard drive failure.
1.5.2 Auto Reassign Sector
Under normal operation, even initially defect-free drive media can develop defects. This is a common phenomenon. The bit density and rotational speed of disks is increasing every year, and so is the potential of problems. Usually a drive can internally remap bad sectors without external help using cyclic redundancy check (CRC) checksums stored at the end of each sector.
SATA drives perform automatic defect re-assignment for both read and write errors. Writes are always completed - if a location to be written is found to be defective, the drive will automatically relocate that write command to a new location and map out the defective location. If there is a recoverable read error, the cor­rect data will be transferred to the host and that location will be tested by the drive to be certain the location is not defective. If it is found to have a defect, data will be automatically relocated, and the defective location is mapped out to prevent future write attempts.
In the event of an unrecoverable read error, the error will be reported to the host and the location agged as potentially defec­tive. A subsequent write to that location will initiate a sector test and relocation should that location have a defect. Auto Reassign Sector does not affect disk subsystem performance because it
23
Page 24
INTRODUCTION
runs as a background task. Auto Reassign Sector discontinues when the operating system makes a request.
1.5.3 Consistency Check
A consistency check is a process that veries the integrity of redundant data. For example, performing a consistency check of a mirrored drive assures that the data on both drives of the mirrored pair is exactly the same. To verify RAID 3, 5 or 6 redun­dancy, a consistency check reads all associated data blocks, com­putes parity, reads parity, and veries that the computed parity matches the read parity. Consistency 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. Note that consistency checks degrade performance, so you should run them when the system load can tolerate it.
1.6 Data Protection
1.6.1 BATTERY BACKUP
The SATA RAID controllers are armed with a Battery Backup Mod­ule (BBM). While a Uninterruptible Power Supply (UPS) protects most servers from power uctuations or failures, a BBM provides an additional level of protection. In the event of a power failure, a BBM supplies power to retain data in the RAID controller’s cache, thereby permitting any potentially dirty data in the cache to be ushed out to secondary storage when power is restored.
The batteries in the BBM are recharged continuously through a trickle-charging process whenever the system power is on. The batteries protect data in a failed server for up to three or four days, depending on the size of the memory module. Under nor­mal operating conditions, the batteries last for three years before replacement is necessary.

INTRODUCTION
1.6.2 RECOVERY ROM
The SATA RAID controller rmware is stored on the ash ROM and is executed by the I/O processor. The rmware can also be updat­ed through the PCI-X/PCIe bus port or Ethernet port (if equipped) without the need to replace any hardware chips. During the con­troller rmware upgrade ash process, it is possible for a problem to occur resulting in corruption of the controller rmware. With our Redundant Flash Image feature, the controller will revert back to the last known version of rmware and continue operating. This reduces the risk of system failure due to rmware crash.
1.7 Understanding RAID
RAID is an acronym for Redundant Array of Independent Disks. It is an array of multiple independent hard disk drives that provides high performance and fault tolerance. The SATA RAID control­ler implements several levels of the Berkeley RAID technology. An appropriate RAID level is selected when the volume sets are dened or created. This decision should be based on the desired disk capacity, data availability (fault tolerance or redundancy), and disk performance. The following section discusses the RAID levels supported by the SATA RAID controller.
The SATA RAID controller makes the RAID implementation and the disks’ physical conguration transparent to the host operating system. This means that the host operating system drivers and software utilities are not affected, regardless of the RAID level selected. Correct installation of the disk array and the control­ler requires a proper understanding of RAID technology and the concepts.
1.7.1 RAID 0
RAID 0, also referred to as striping, writes stripes of data across multiple disk drives instead of just one disk drive. RAID 0 does not provide any data redundancy, but does offer the best high­speed data throughput. RAID 0 breaks up data into smaller blocks and then writes a block to each drive in the array. Disk strip­ing enhances performance because multiple drives are accessed
25
Page 26
INTRODUCTION
simultaneously; the reliability of RAID Level 0 is less because the entire array will fail if any one disk drive fails, due to a lack of redundancy.
1.7.2 RAID 1
RAID 1 is also known as “disk mirroring”; data written to one disk drive is simultaneously written to another disk drive. Read per­formance may be enhanced if the array controller can, in parallel, accesses both members of a mirrored pair. During writes, there will be a minor performance penalty when compared to writing to a single disk. If one drive fails, all data (and software applica­tions) are preserved on the other drive. RAID 1 offers extremely high data reliability, but at the cost of doubling the required data storage capacity.
26
Page 27
INTRODUCTION
1.7.3 RAID 1E
RAID 1E is a combination of RAID 0 and RAID 1, combing strip­ping with disk mirroring. RAID Level 1E combines the fast per­formance of Level 0 with the data redundancy of Leve1 1. In this conguration, data is distributed across several disk drives, similar to Level 0, which are then duplicated to another set of drive for data protection. RAID 1E has been traditionally imple­mented using an even number of disks, some hybrids can use an odd number of disks as well. Illustration is an example of a hy­brid RAID 1E array comprised of ve disks; A, B, C, D and E. In this conguration, each strip is mirrored on an adjacent disk with wrap-around. In fact this scheme - or a slightly modied version of it - is often referred to as RAID 1E and was originally proposed by IBM. When the number of disks comprising a RAID 1E is even, the striping pattern is identical to that of a traditional RAID 1E, with each disk being mirrored by exactly one other unique disk. Therefore, all the characteristics for a traditional RAID 1E apply to a RAID 1E when the latter has an even number of disks. Areca RAID 1E offers a little more exibility in choosing the number of disks that can be used to constitute an array. The number can be even or odd.
1.7.4 RAID 3
RAID 3 provides disk striping and complete data redundancy though a dedicated parity drive. RAID 3 breaks up data into smaller blocks, calculates parity by performing an exclusive-or on the blocks, and then writes the blocks to all but one drive in
27
Page 28
INTRODUCTION
the array. The parity data created during the exclusive-or is then written to the last drive in the array. If a single drive fails, data is still available by computing the exclusive-or of the contents cor­responding strips of the surviving member disk. RAID 3 is best for applications that require very fast data- transfer rates or long data blocks.
1.7.5 RAID 5
RAID 5 is sometimes called striping with parity at byte level. In RAID 5, the parity information is written to all of the drives in the controllers rather than being concentrated on a dedicated parity disk. If one drive in the system fails, the parity information can be used to reconstruct the data from that drive. All drives in the array system can be used for seek operations at the same time, greatly increasing the performance of the RAID system. This relieves the write bottleneck that characterizes RAID 4, and is the primary reason that RAID 5 is more often implemented in RAID arrays.
28
Page 29
INTRODUCTION
1.7.6 RAID 6
RAID 6 provides the highest reliability, but is not yet widely used. It is similar to RAID 5, but it performs two different parity com­putations or the same computation on overlapping subsets of the data. RAID 6 can offer fault tolerance greater than RAID 1 or RAID 5 but only consumes the capacity of 2 disk drives for dis­tributed parity data. RAID 6 is an extension of RAID 5 but uses a second, independent distributed parity scheme. Data is striped on a block level across a set of drives, and then a second set of par­ity is calculated and written across all of the drives.
Summary of RAID Levels

Step 3. Install the PCI RAID Cards
To install the SATA RAID controller remove the mounting screw and existing bracket from the rear panel behind the selected PCI slot. Align the gold-ngered edge on the card with the selected PCI expansion slot. Press down gently but rmly to ensure that the card is properly seated in the slot, as shown in Figure 2-11. Next, screw the bracket into the computer chassis. ARC-11xx controllers can t in both PCI (32-bit/3.3V) and PCI-X slots. It can get the best performance installed in a 64-bit/133MHz PCI-X slot. ARC-12xx controllers require a PCI-Express 8X slot.
Figure 2-11, Insert SATA RAID controller into a PCI-X slot
Step 4. Mount the Cages or Drives
Remove the front bezel from the computer chassis and install the Cages or SATA Drives in the computer chassis. Loading drives to the drive tray if cages are installed. Be sure that the power is con­nected to either the Cage backplane or the individual drives.

Step 5 Connect the SATA cable
Model ARC-11XX and ARC-12XX controllers have dual-layer SATA internal connectors. If you have not already connected your SATA cables, use the cables included with your kit to connect the control­ler to the SATA hard drives. The cable connectors are all identical, so it does not matter which end you connect to your controller, SATA hard drive, or cage back­plane SATA connector.
Figure 2-13, SATA Cable
Note:
The SATA cable connectors must match your HDD cage. For example: Channel 1 of RAID Card connects to channel 1 of HDD cage, channel 2 of RAID Card connects to channel 2 of HDD cage, and follow this rule.

Step 5-2. Connect the Multi-lance cable
Model ARC-11XXML has multi-lance internal connectors, each of them can support up to four SATA drives. These adapters can be installed in a server RAID enclosure with a Multi-lance connector (SFF-8470) backplane. Multi-lance cables are not included in the ARC-11XXML package. If you have not already connected your Multi-lance cables, use the cables included with your enclosure to connect your controller to the Multi-lance connector backplane. The type of cable will depend on what enclosure you have. The following diagram shows one ex­ample picture of Multi-lane cable. Unpack and remove the PCI RAID cards. Inspect it carefully. If any­thing is missing or damaged, contact your local dealer.
Figure 2-14, Multi-Lance Cable
Step 5-3. Connect the Min SAS 4i to 4*SATA cable

HARDWARE INSTALLATION
The intelligent LED controller outputs a low-level pulse to deter­mine if status LEDs are attached to pin sets 1 and 2. This allows automatic controller conguration of the LED output. If the logi­cal level is different between the st 2 sets of the HDD LED header (LED attached to Set 1 but not Set 2), the controller will assign the rst HDD LED header as the global indicator connector. Otherwise, each LED output will show only individual drive status.
The SATA RAID controller provides four kinds of LED status connec­tors.
A: Global indicator connector, which lights when any drive is active. B: Individual LED indicator connector, for each drive channel. C: I2C connector, for SATA proprietary backplane enclosure. D: SGPIO connector for SAS Backplane enclosure
The following diagrams and description describes each type of con­nector.
Note:
A cable for the global indicator comes with your computer system. Cables for the individual drive LEDs may come with a drive cage, or you may need to purchase them.
A: Global Indicator Connector
If the system will use only a single global indicator, attach the global indicator cable to the two pins HDD LED connector. The fol­lowing diagrams show the connector and pin locations.

Connect the cables for the drive activity LEDs and fault LEDs be­tween the backplane of the cage and the respective connector on the SATA RAID controller. The following describes the fault/activ­ity LED.
LED Normal Status Problem Indication
Activity LED When the activity LED is illu-
minated, there is I/O activity on that disk drive. When the LED is dark, there is no activ­ity on that disk drive.
Fault LED When the fault LED is solid
illuminated, there is no disk present. When the fault LED is off, that disk is present and sta­tus is normal.
N/A
When the Red LED is slow blinking (2 times/sec), that disk drive has failed and should be hot-swapped immediately. When the activity LED is illuminated and Red LED is fast blinking (10 times/sec) there is rebuilding activity on that disk drive.

D: SGPIO bus
The preferred I/O connector for server backplanes is the Min SAS 4i internal serial-attachment connector. This connector has eight signal pins to support four SATA drives and six pins for the SGPIO (Serial General Purpose Input/Output) side-band signals. The SGPIO bus is used for efcient LED management and for sens­ing drive Locate status. See SFF 8485 for the specication of the SGPIO bus.
The number of drives supported can be increased, by a factor of four, by adding similar backplane to maximum of 24 drives (6 backplanes)
LED Management: The backplane may contain LEDs to indicate drive status. Light from the LEDs could be transmitted to the out­side of the server by using light pipes mounted on the SAS drive tray. A small EPLP microcontroller on the backplane, connected via the SGPIO bus to a ARC-1231ML/1261ML/1280ML SATA RAID con­troller, could control the LEDs. Activity: blinking 5 Times/Second Fault: solid illuminated
Drive Locate Circuitry: The locate of a drive may be detected by sensing the voltage level of one of the pre-charge pins before and after a drive is installed. Fault (red) blinking 2 Times/Second.

HARDWARE INSTALLATION
The following signal denes the sideband connector which can work with Areca sideband cable.
The sideband header is located at backplane. For SGPIO to work properly, please connect Areca 8-pin sideband cable to the sideband header as shown above. See the table for pin denitions.
Step 7. Re-check the SATA HDD LED and Fault LED Cable connections
Be sure that the proper failed drive channel information is displayed by the Fault and HDD Activity LEDs. An improper connection will tell the user to ‘‘Hot Swap’’ the wrong drive. This will remove the wrong disk (one that is functioning properly) from the controller. This can result in failure and loss of system data.
Step 8. Power up the System
Thoroughly check the installation, reinstall the computer cover, and reconnect the power cord cables. Turn on the power switch at the rear of the computer (if equipped) and then press the power button at the front of the host computer.
Step 9. Congure volume set
The SATA RAID controller congures RAID functionality through the McBIOS RAID manager. Please refer to Chapter 3, McBIOS RAID manager, for the detail regarding conguration. The RAID controller can also be congured through the McRAID storage manager soft­ware utility with ArcHttp proxy server installed through on-board Lan port or LCD module. For this option, please reference Chapter 6, Web Browser-Based Conguration or LCD conguration menu.

HARDWARE INSTALLATION
Step 10. Install the controller driver
For a new system:
• Driver installation usually takes places as part of operating sys­tem installation. Please reference the Chapter 4 Diver Installation for the detail installation procedure.
In an existing system:
• Install the controller driver into the existing operating system. Please reference the Chapter 4, Driver Installation, for the detailed installation procedure.
Note:
Look for newest release versions of drivers please download from http://www.areca.com.tw
Step 11. Install ArcHttp proxy Server
The SATA RAID controller rmware has embedded the web-browser RAID manager. ArcHttp proxy driver will enable it. The browser­based RAID manager provides all of the creation, management, and monitor SATA RAID controller status. Please refer to the Chapter 5 for the detail ArcHttp proxy server installation. For SNMP agent function, please refer to Appendix C.
Step 12. Determining the Boot sequences
The SATA RAID controller is a bootable controller. If your system already contains a bootable device with an installed operating sys­tem, you can set up your system to boot a second operating sys­tem from the new controller. To add a second bootable controller, you may need to enter setup and change the device boot sequence so that the SATA RAID controller heads the list. If the system BIOS setup does not allow this change, your system may not be con­gurable to allow the SATA RAID controller to act as a second boot device.

The system mainboard BIOS automatically congures the following SATA RAID controller parameters at power-up:
• I/O Port Address
• Interrupt channel (IRQ)
• Adapter ROM Base Address
Use McBIOS to further congure the SATA RAID controller to suit your server hardware and operating system.
3.1 Starting the McBIOS RAID Manager
This section explains how to use the McBIOS Setup Utility to con­gure your RAID system. The BIOS Setup Utility is designed to be user-friendly. It is a menu-driven program, residing in the rm­ware, which allows you to scroll through various menus and sub­menus and select among the predetermined conguration options.
When starting a system with an SATA RAID controller installed, it will display the following message on the monitor during the start­up sequence (after the system bios startup screen but before the operating system boots):
ARC-1xxx RAID Ctrl - DRAM: 128(MB) / #Channels: 8

3.2 McBIOS Conguration manager
The McBIOS conguration utility is rmware-based and is used to congure raid sets and volume sets. Because the utility resides in the SATA RAID controller rmware, operation is independent of any operating systems on your computer. This utility can be used to:
• Create RAID sets,
• Expand RAID sets,
57
Page 58
BIOS CONFIGURATION
• Add physical drives,
• Dene volume sets,
• Modify volume sets,
• Modify RAID level/stripe size,
• Dene pass-through disk drives,
• Modify system functions, and
• Designate drives as hot spares.
3.3 Conguring Raid Sets and Volume Sets
You can congure RAID sets and volume sets with McBIOS RAID manager automatically using Quick Volume/Raid Setup or manually using Raid Set/Volume Set Function. Each conguration method re­quires a different level of user input. The general ow of operations for RAID set and volume set conguration is:
Step Action
1 Designate hot spares/pass-through drives (optional).
2 Choose a conguration method.
3 Create RAID sets using the available physical drives.
4 Dene volume sets using the space available in the RAID Set.
5 Initialize the volume sets and use volume sets (as logical drives) in the
host OS.
3.4 Designating Drives as Hot Spares
Any unused disk drive that is not part of a RAID set can be desig­nated as a Hot Spare. The “Quick Volume/Raid Setup” conguration will add the spare disk drive and automatically display the appro­priate raid level from which the user can select. For the “Raid Set Function conguration” option, the user can use the “Create Hot Spare” option to dene the hot spare disk drive.
When a Hot Spare disk drive is being created using the “Create Hot Spare” option (in the Raid Set Function), all unused physical de­vices connected to the current controller appear: Choose the target disk by selecting the appropriate check box. Press the Enter key to select a disk drive, and press Yes in the Create Hot Spare to designate it as a hot spare.

3.5 Using Quick Volume /Raid Setup Con-
guration
Quick Volume / Raid Setup Conguration collects all available drives and includes them in a RAID set. The RAID set you create is associated with exactly one volume set. You will only be able to modify the default RAID level, the stripe size, and the capacity of the new volume set. Designating drives as Hot Spares is also possible in the raid level selection option. The volume set default settings will be:
Parameter Setting
Volume Name Volume Set # 00
SCSI Channel/SCSI ID/SCSI LUN 0/0/0
Cache Mode Write Back
Tag Queuing Yes
The default setting values can be changed after conguration is complete. Follow the steps below to create arrays using the RAID Set / Volume Set method:
Step Action
1 Choose Quick Volume /Raid Setup from the main menu. The available
RAID levels with hot spare for the current volume set drive are displayed.
2 It is recommend that you drives of the same capacity in a specic array.
If you use drives with different capacities in an array, all drives in the raid set will be set to the capacity of the smallest drive in the raid set. The numbers of physical drives in a specic array determines which RAID levels that can be implemented in the array. RAID 0 requires 1 or more physical drives. RAID 1 requires at least 2 physical drives. RAID 1+Spare requires at least 3 physical drives. RAID 1E requires at least 4 physical drives. RAID 3 requires at least 3 physical drives. RAID 5 requires at least 3 physical drives. RAID 3 +Spare requires at least 4 physical drives. RAID 5 + Spare requires at least 4 physical drives. RAID 6 requires at least 4 physical drives. RAID 6 + Spare requires at least 5 physical drives. Highlight the desired RAID level for the volume set and press the Enter key to conrm.

3.7.1 Quick Volume/RAID Setup
“Quick Volume/RAID Setup” is the fastest way to prepare a RAID set and volume set. It requires only a few keystrokes to com­plete. Although disk drives of different capacity may be used in the RAID set, it will use the capacity of the smallest disk drive as the capacity of all disk drives in the RAID set. The “Quick Vol­ume/RAID Setup” option creates a RAID set with the following properties:
1. All of the physical drives are contained in one RAID set.
2. The RAID level, hot spare, capacity, and stripe size options are selected during the conguration process.
3. When a single volume set is created, it can consume all or a portion of the available disk capacity in this RAID set.
4. If you need to add an additional volume set, use the main menu “Create Volume Set” function.

A volume set is seen by the host system as a single logical de­vice; it is organized in a RAID level within the controller utiliz­ing one or more physical disks. RAID level refers to the level of data performance and protection of a volume set. A volume set can consume all of the capacity or a portion of the available disk capacity of a RAID set. Multiple volume sets can exist on a RAID set. If multiple volume sets reside on a specied RAID set, all
72

volume sets will reside on all 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 rather than one volume set using some of the available disks and another volume set using other disks.

1. Volume sets of different RAID levels may coexist on the same raid set.
2. Up to 16 volume sets in a RAID set can be created by the SATA RAID controller.

3.7.5.8 Stagger Power On
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. New SATA drives have support staggered spin-up capabilities to boost reliability. Staggered spin-up is a very useful feature for managing multiple disk drives in a storage subsystem. 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. Staggering 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.

3.7.5.10 HDD SMART Status Polling
An external RAID enclosure has the hardware monitor in the dedicated backplane that can report HDD temperature status to the controller. However, PCI cards do not use backplanes if the drives are internal to the main server chassis. The type of enclosure cannot report the HDD temperature to the controller. For this reason, HDD SMART Status Polling was added to enable scanning of the HDD temperature function in the version 1.36 date: 2005-05-19 (and later). It is necessary to enable “HDD SMART Status Polling” function before SMART information is accessible. This function is disabled by default. The following screen shot shows how to change the BIOS setting to enable the Polling function.

ity of a drive that is used in redundant units. The controller provides three truncation modes in the system conguration: Multiples Of 10G, Multiples Of 1G, and No Truncation. 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. Areca drive Truncation mode Multiples Of 10G uses the 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. Areca drive Truncation mode Multiples Of 1G uses the same capacity for both of these drives so that one could replace the other.
No Truncation: It does not truncate the capacity.

3.7.6.1 DHCP Function
DHCP (Dynamic Host Conguration Protocol) allows network ad­ministrators centrally manage and automate the assignment of IP (Internet Protocol) addresses on a computer network. When using the TCP/IP protocol (Internet protocol), it is necessary for a computer to have a unique IP address in order to communi­cate to other computer systems. 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 congurations for a specic time period (called a lease period) and to minimize the work necessary to administer a large IP network.

Select the “Disabled’ or ‘Enabled” option to enable or disable the DHCP function. If DHCP is disabled, it will be necessary to manually enter a static IP address that does not conict with other de­vices on the network.
3.7.6.2 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 administrative errors and duplicate addresses. To manually congure the IP address of the controller, move the cursor bar to the Main menu Ethernet Conguration Function item and then press the Enter key. The Ethernet Conguration menu appears on the screen. Move the cursor bar to Local IP Address item, then press the Enter key to show the default address setting in the SATA RAID controller. You can then reassign the static IP address of the controller.

A MAC address stands for “Media Access Control” address and is unique to every single ethernet device. On an Ethernet LAN, it’s the same as your Ethernet address. When you’re connected to a local network from the SATA RAID controller Ethernet port, a correspondence table relates your IP address to the SATA RAID controller’s physical (MAC) address on the LAN.
