Chapter 3 Functional Description The advantages of RAID are: Availability, Capacity and Performance. Choosing the right RAID level and drive failure management can increase Availability, subsequently increasing Performance and Capacity. The ASUS PCI-DA2200 RAID controller provides complete RAID functionality and enhanced drive failure management. 3.1 RAID Management RAID stands for Redundant Array of Independent Drives.
NRAID Disk Spanning 2 GB Hard Drive + 3 GB Hard Drive + 1 GB Hard Drive + 2 GB Hard Drive = NRAID Minimum Disks required Capacity Redundancy 1 Logical Drive N No 2 + 3 + 1 + 2 = 8 GB Logical Drive NRAID stands for Non-RAID. The capacity of all the drives are combined to become one logical drive (no block striping). In other words, the capacity of the logical drive is the total capacity of the physical drives. NRAID does not provide data redundancy.
RAID 0 Disk Striping Logical Drive Physical Disks Block 1 RAID 0 Minimum Disks required Capacity Redundancy Striping Block 2 Block 3 Block 1 Block 2 Block 4 Block 5 Block 3 Block 5 Block 4 Block 6 2 Block 6 Block 7 Block 8 . . Block 8 . . N No Block 7 . . RAID 0 provides the highest performance but no redundancy. Data in the logical drive is striped (distributed) across several physical drives.

Spare Drive will join that logical drive and automatically starts to rebuild. Global Spare Drive Global Spare Drive GS 1 GS 2 1 2 3 Logical Drive 0 Logical Drive 1 3 Logical Drive 0 X 1 2 2 4 3 When a member drive from any logical drive fails, the Global Spare Drive joins that logical drive and automatically starts to rebuild. GS 2 1 Logical Drive 2 Global Spare Drive 1 Global Spare Drives serve any logical drives.
using a 9GB drive as the Global Spare drive for a failed drive that comes from Logical Drive 1 or 2 will bring huge amount of excess capacity since these logical drives require 4 GB only. In the settings below, the 9 GB Local Spare Drive will aid Logical Drive 0 once a drive in this logical drive failed. If the failed drive is in Logical Drive 1 or 2, the 4 GB Global Spare drive will immediately give aid to the failed drive.
Flash Selected SCSI Drive The Read/Write LED of the drive you selected will light steadily for about one minute. R/W LED R/W LED LED Steadily ON R/W LED R/W LED Flash All SCSI Drives The Read/Write LED of all connected drives will light for about one minute. If the LED of the defective drive did not light on the “Flash Selected SCSI Drive” function, use “Flash All SCSI Drives”. The “Flash All SCSI Drives” function will light LEDs of all the drives except the defective one.
Rebuild Automatic Rebuild Any local spare drive assigned to logical drive? One member drive fails in logical drive Yes Rebuild using the local spare drive Yes Rebuild using the global spare drive Yes Rebuild using the swapped drive No Any global spare drive assigned to logical drive? No Waiting for spare drive to be added or manual rebuild No “Periodic Auto-Detect Failure Drive Swap Check Time” enabled? Yes Has the failed drive been swapped? No Keep detecting if drive has been swapped or spare dri
If the failed drive is not swapped but a local spare drive is added to the logical drive, rebuilding will begin with the spare drive. Manual Rebuild When a user applies forced-manual rebuild, the controller will first check whether there is any Local Spare Drive assigned to this logical drive. If yes, it will automatically start to rebuild. If there is no Local Spare Drive available, the controller will search for a Global Spare Drive.
3.2.4 Concurrent Rebuild in RAID (0+1) RAID (0+1) allows multiple drive failure and concurrent multiple drive rebuild. Newly replaced drives must be scanned and set as Local Spare Drives. These drives will be rebuilt at the same time (you do not need to repeat the rebuilding process for each drive). 3.3 Disk Array Parameters 3.3.1 Rebuild Priority Rebuilding time will depend on the capacity of the logical drive. The ASUS PCI-DA2200 RAID controller provides background rebuilding ability.
Each method can be enabled or disabled individually. Hard drives will perform Verify-after-Write according to the selected method.
ASUS PCI-DA2200 User’s Manual 3-13
IMPORTANT: The “Verification on LD Normal Drive Writes” method will affect “write” performance during normal use. 3.4 3.4.1 Cache Parameters Optimization for Sequential or Random I/O When using RAID with applications such as video or image oriented applications, the application reads/writes from the drive using largeblock, sequential files instead of small-block, random access files.
ASUS PCI-DA2200 User’s Manual 3-15
IMPORTANT: Changing the setting to “Optimization for Sequential I/O” or “Optimization for Random I/O” should be performed only when no logical drive exist. Otherwise, you will not be able to access the data in the logical drive later on. 3.5 3.5.
ASUS PCI-DA2200 User’s Manual 3-17
IMPORTANT: If the drives are configured as “Delay Motor Spin-up” or “Motor Spin-up in Random Sequence,” some of these drives may not be ready yet for the controller to access when the system powers up. Increase the disk access delay time so that the controller will wait a longer time for the drive to be ready. 3.5.2 SCSI Reset at Power Up By default, when the controller is powered up, it will send a SCSI bus reset command to the SCSI bus.
is still retrying or while a drive is unable to arbitrate the SCSI bus. Setting the timeout to a greater value will cause the controller to keep waiting for a drive, and it may sometimes cause a host timeout. 3.5.5 Maximum Tag Count The maximum number of tags that can be sent to each drive at the same time. A drive has a built-in cache that is used to sort all of the I/O requests (“tags”) which are sent to the drive, allowing the drive to finish the requests faster.
controller communicates with the SAF-TE enclosure with standard SCSI commands, polling the device in order to get SAF-TE information. The default value for “Periodic SAF-TE Device Check Time” is “Disabled”. If the enclosure does have a SAF-TE device and features, enable the controller to poll the device by selecting a time interval. The RAID controller will then check the SAF-TE device status at that interval.
3.6 3.6.1 Dynamic Logical Drive Expansion What Is It and How Does It Work? Before Dynamic Logical Drive Expansion, increasing the capacity of a RAID system using traditional methods meant backing up, recreating and then restoring. Dynamic Logical Drive Expansion allows users to add new SCSI hard disk drives and expand a RAID 0, 3 or 5 Logical Drive without powering down the system. 3.6.
RAID Expansion - Mode 1 2GB 2GB 2GB 2GB 2GB + + RAID 5 Logical Drive - 4GB Add-in New Drives 2GB 2GB 2GB 2GB 2GB RAID Expansion RAID 5 Logical Drive - 8GB In the figure above, new drives are added to increase the capacity of a 4-Gigabyte RAID 5 logical drive. The two new drives increase the capacity to 8 Gigabytes. Mode 2 Expansion, on the other hand, requires the same number of higher-capacity SCSI hard disk drives for a given logical drive.
This results in a new 4-Gigabyte, RAID 5 logical drive composed of RAID Expansion - Mode 2 (2/3) 2 2 GB 2 GB 4 GB 4 GB New Drive RAID 5 (4GB) Copy and Replace the other member drives one by one until all the member drives have been replaced Copy and Replace each member drive. After all the member drives have been replaced, execute the “RAID Expansion” to use the additional capacity. In use Unused three physical drives. The 4 Gigabytes of increased capacity is in a new partition.
3-24 ASUS PCI-DA2200 User’s Manual
IMPORTANT: • The increased capacity from Mode 1 and Mode 2 Expansion of a logical drive will be a new partition. • Adding the extra capacity to the existing partition could crash the file system in most current operating systems, so this is not supported. Technically, the controller could easily combine the two partitions together.
The Example: The following example demonstrates the expansion of a 900MB RAID 0 logical drive. The Text RAID Manager software that comes with the ASUS PCI-DA2200 is used to communicate with the RAID controller. You can view information about this drive in the Windows NT Server’s Disk Administrator.
Place the cursor on Disk 1, right-click your mouse, and select "Properties." You will see that the total capacity for the Drive E: is just under 900MB.
Follow the steps described in section 8.2.8 to add SCSI disk drives and perform Mode 1 Dynamic Logical Drive Expansion. The 900MB logical drive has become a 1800MB logical drive. Place the cursor on that logical drive, and then press .
From the menu, select Partition Logical Drive. You will see that the 1800MB logical drive is composed of two 900MB partitions. Follow the directions in section 8.3.1 to map the new partition to a Host LUN. The new partition must be mapped to a host LUN in order for the HBA (host-bus adapter) to see it. Once you have mapped the partition, reboot Windows NT. The HBA should be able to detect an additional "disk.
Return to Windows NT Server’s Disk Administrator. There now exists a Disk 2 with 900MB of free space. Click on Disk 2 to select it. From the "Partition" menu, select "Extend Volume Set.
The screen will display that volume set of Drive E: has been extended by the 900MB in Disk2. Move the cursor to "Commit Changes Now" to confirm that you want the free space to become a part of the same logical drive.
Logical Drive E: is now composed of two 900MB partitions with a total volume of 1800MB. To see this, hold down on the key and select both Disk 1 and Disk2; then right-click your mouse and select "Properties.
Drive E: now has a capacity just under 1800MB.

NOTE: A “Logical Drive” is a set of drives grouped together to operate under a given RAID level and appears as a single contiguous drive. The ASUS PCIDA2200 controller is capable of grouping connected drives to as many as 8 logical drives, each configured on the same or different RAID levels. A logical drive can be further divided into a maximum of 8 “Partitions”. During operation, the host sees an unpartitioned logical drive or a partition of a partitioned logical drive as one single physical drive.
6.2 6.2.1 How Does the RAID Controller Work? SCSI Channel, SCSI ID and LUN A SCSI channel (SCSI bus) can connect up to 15 devices (the SCSI controller itself excluded) when the Wide function is enabled (16-bit SCSI). It can connect up to 7 devices (the SCSI controller itself excluded) when the Wide function is disabled (8-bit SCSI). Each device has one unique SCSI ID. Two devices having the same SCSI ID is not allowed. LUN 0 LUN 1 LUN 2 6-4 The figure on the left illustrates this.

2 Installation This chapter contains information about software setup and hardware setup for local and remote management.
ASUS GUI RAID Manager: Installation 2.1 System Requirements The minimum hardware and software requirements for the GUI RAID Manager are listed below.
ASUS GUI RAID Manager: Installation 2.2 Hardware Setup The GUI RAID Manager supports both local and remote management of the ASUS’ disk array system. Local management refers to management of the disk array from a local host − management transactions traverse the PCI bus (for PCI-toSCSI controller) or an RS-232 cable (for SCSI-to-SCSI controller) connected between the controller and the host’s serial interface.
ASUS GUI RAID Manager: Installation 2.2.1 Local Management For local management, the controller is either installed in (for PCI-to-SCSI controller) or connected to (for SCSI-to-SCSI controller) the host. The following figure illustrates a typical setup for a PCI-to-SCSI controller: GUI RAID Manager Station PCI-to-SCSI RAID Controller PCI Bus Since the controller is already installed in the host, no extra connection is necessary.
ASUS GUI RAID Manager: Installation 4Setting up a SCSI-to-SCSI controller using RS-232 1. Connect the RS-232 port of the SCSI-to-SCSI controller to a null modem using the appropriate RS-232 cable. Do the same to the serial interface of the local host. If your local host has more than one serial interface, write down the corresponding port number of the selected port (that is, COM1, COM2, etc.). 2.
ASUS GUI RAID Manager: Installation 2.2.2 Remote Management You can set up your hardware two ways in remote management: network and telephone. Network setup provides a faster data transfer rate than the telephone setup for it utilizes the network bandwidth of 10 Mbps (million bits per second) for Ethernet, 100 Mbps for Fast Ethernet, and so on; the telephone setup is restricted to the speed of the modem, which is 38.4 Kbps maximum (currently).
ASUS GUI RAID Manager: Installation Local Host GUI RAID Manager Station RS-232 RS-232 (Windows 95, Windows NT) Modem/Fax Modem/Fax Telephone Line SCSI Bus SCSI-to-SCSI RAID Controller To manage the disk array system, just dial in the number of the modem connected to the SCSI-to-SCSI controller. NOTES: Ensure that the baud rates of the RS-232 port and the modem are set accordingly; otherwise, you will encounter communication problems.
ASUS GUI RAID Manager: Installation 2.3 In-band SCSI What is it and what is it used for? These days more and more external devices require communication with the host computer for device monitoring and administration. This is usually done through RS-232C ports. An alternative means of communication is now available for SCSIto-SCSI RAID controllers—In-band SCSI.
ASUS GUI RAID Manager: Installation controller and to the host computer's SNMP settings before the two can communicate using SCSI commands. (Note: The SNMP settings must be changed prior to installation of the GUI RAID Manager. See SNMP Settings below for a detailed explanation.)

ASUS GUI RAID Manager: Array Management 4.1 Background Information Redundant Arrays of Independent Disks (RAID) is a storage technology used to improve the processing capability of storage systems. This technology is designed to provide reliability in disk array systems and to take advantage of the performance gains multiple disks can offer. RAID comes with a redundancy feature that ensures faulttolerant, uninterrupted disk storage operations.
ASUS GUI RAID Manager: Array Management immediately commence. Spare drives appear in darker (shaded) colors than normal drives. ♦ Replacement drives. These are physical drives that are manually configured into the array to replace failed drives. In the absence of spare drives, you will need to use replacement drives to replace defective drives before rebuilding can be performed. ♦ Failed drives. These are physical drives that fail due to errors of some type.
ASUS GUI RAID Manager: Array Management ♦ If a spare drive exists in the same logical drive, the controller will automatically mount the spare drive and start data rebuilding in the background. ♦ Depending on the design of the system external to the controller, it may be possible to remove a defective drive and replace it with a new drive without shutting down the system (hot-swapping). Alternatively, the system can be shut down at a convenient time and the failed drive replaced.
ASUS GUI RAID Manager: Array Management same logical drive. A defective drive must be promptly replaced and data rebuilt. CAUTION: When performing hot-swapping, be sure to remove only the defective drive. Removing the wrong drive will result in unrecoverable data loss. Use the Enclosure or Physical Drives window to locate the exact location of the failed drive. 4-6 4.
ASUS GUI RAID Manager: Array Management 4.3 Before you Start The GUI RAID Manager station comes with password protection that prevents unauthorized modification of the disk array configuration.

To select, click on the down-arrow button at the right of this box and then select the option you want.
ASUS GUI RAID Manager: Array Management 3. Select Delete. 4.9 Assigning Spare Drives You can assign spare drives to a logical drive to serve as backups for failed drives. In the event of a drive failure, the spare drive will be automatically configured into the array and reconstruction (or rebuilding) will immediately commence. Logical drives can support multiple spare drives; this configuration however is rarely used due to its high cost and uncommon occurrences of drive failures.
ASUS GUI RAID Manager: Array Management NOTE: Adding a spare drive can be done automatically by selecting the 1+Spare, 3+Spare or 5+Spare option from the Logical Drive Selection dialog box when creating a logical drive. These options however only apply to RAID 1, RAID 3, and RAID 5 levels respectively. 4 Assigning a spare drive 1. Display the Physical Drives and Logical Drives windows.
ASUS GUI RAID Manager: Array Management 4.10 Rebuilding Logical Drives Depending on whether or not there is a spare drive, rebuilding is initiated automatically or manually. In the presence of a spare drive, the system automatically rebuilds onto the spare drive. This process is done in the background, thus it appears transparent to the user. In the absence of a spare drive, rebuilding must be initiated manually. Before initiating a manual rebuild, you need to first replace the failed drive.
ASUS GUI RAID Manager: Array Management 4.11 Creating and Deleting Logical Volumes You can create and delete logical volumes from your GUI RAID Manager station. Logical volumes are created by simply combining unassigned logical drives together. You can combine logical drives with different capacities and RAID levels into one logical volume. Alternatively, you can delete existing logical volumes. Before deleting though, be sure that the data stored in the logical volume is no longer needed.
ASUS GUI RAID Manager: Array Management 6. Select Volume. Then, from the next menu, select Create LV. The logical volume is now created. You may now define its partitions. See the Creating and Deleting Partitions section of this chapter. 4-26 4.

Repeat the same procedure for the other remaining partitions on the logical volume to be mapped. 4 Deleting a host LUN mapping 1.
ASUS GUI RAID Manager: Array Management 4.14 Displaying the Event Log The GUI RAID Manager keeps a log file for documenting all events that occurred in the disk array system ranging from simple notifications, to warnings, to alerts. The GUI RAID Manager saves the system log into a file named EVENT.LOG in the GUI RAID Manager directory. You can view the contents of this text file using any text editor program such as Windows’ NOTEPAD application.
ASUS GUI RAID Manager: Array Management 2. To scroll through the list, use the vertical scroll bars. 4.
ASUS GUI RAID Manager: Array Management 4.15 Monitoring Statistics The GUI RAID Manager comes with a statistics monitoring feature to report on the overall performance of the disk array system. This feature provides a real-time report on the current throughput of the system, displaying the number of bytes being read and written per second. These values are displayed in a graphical format to facilitate reference.
ASUS GUI RAID Manager: Array Management 4.16 Dynamic Logical Drive Expansion What Is It and How Does It Work? Before Dynamic Logical Drive Expansion, increasing the capacity of a RAID system using traditional methods meant backing up, re-creating and then restoring. Dynamic Logical Drive Expansion (a new feature of firmware version 2.11) allows users to add new SCSI hard disk drives and expand a RAID 0, 3 or 5 Logical Drive without powering down the system. 4.16.
ASUS GUI RAID Manager: Array Management Mode 1 Expansion involves adding more SCSI hard disk drives to a logical drive, which may require that the user obtain an enclosure with more drive bays. The data will be re-striped onto the original and newly added disks.
ASUS GUI RAID Manager: Array Management Mode 2 Expansion, on the other hand, requires the same number of higher-capacity SCSI hard disk drives for a given logical drive. RAID Expansion - Mode 2 (1/3) 2 GB 2 GB 2 GB The original logical drive RAID 5 (4GB) 4 GB 1 2 GB 2 GB 2 GB New Drive RAID 5 (4GB) Copy and Replace one of the member drives Copy and Replace each of the member drives. Even if one member drives fails during the Copy and Replace, the logical drive will still be available for access.
ASUS GUI RAID Manager: Array Management RAID Expansion - Mode 2 (2/3) 2 2 GB 2 GB 4 GB 4 GB New Drive RAID 5 (4GB) Copy and Replace the other member drives one by one until all the member drives have been replaced Copy and Replace each member drive. After all the member drives have been replaced, execute the “RAID Expansion” to use the additional capacity. In use Unused This results in a new 4-Gigabyte, RAID 5 logical drive composed of three physical drives.
ASUS GUI RAID Manager: Array Management F IMPORTANT: • The increased capacity from Mode 1 Expansion of a logical drive will be a new partition. • At the time of this printing, Firmware version 2.11 does not support the "Copy and Replace" function that is required for Mode 2 Expansion. Third-party hard disk utilities may be used for Mode 2 Expansion of logical drives. Later versions of the firmware will support "Copy and Replace.
ASUS GUI RAID Manager: Array Management The Example: The following example demonstrates the expansion of a 900MB RAID 0 logical drive. The GUI RAID Manager is used to connect to the RAID controller. You can view information about this drive in the Windows NT Server’s Disk Administrator. 4-42 4.
ASUS GUI RAID Manager: Array Management Place the cursor on Disk 1, right-click your mouse, and select "Properties." You will see that the total capacity for the Drive E: is just under 900MB. 4.
ASUS GUI RAID Manager: Array Management Three new drives are scanned in (see section 4.7 for details on scanning in new drives.) To add the drives to the logical drive, first right-click on the logical drive icon, and then select "Add SCSI Drive." The logical drive icon will appear to be degraded while the new drives are being added to the logical drive. The color will return to normal once the adding the drives has been completed.
ASUS GUI RAID Manager: Array Management From the menu, select Partition Logical Drive. You will see that the 1800MB logical drive is composed of two 900MB partitions. Follow the directions in section 4.13 to map the new partition to a Host LUN. The new partition must be mapped to a host LUN in order for the HBA (host-bus adapter) to see it. Once you have mapped the partition, reboot Windows NT. The HBA should be able to detect an additional "disk." Return to Windows NT Server’s Disk Administrator.

C RAID Levels This appendix provides a functional description of Redundant Array of Independent Disks (RAID). This includes information about RAID and available RAID levels. RAID Description Redundant Array of Independent Disks (RAID) is a storage technology used to improve the processing capability of storage systems. This technology is designed to provide reliability in disk array systems and to take advantage of the performance gains multiple disks can offer.
ASUS GUI RAID Manager: RAID Levels would create a single logical drive with a total disk capacity of 4GB. Disk spanning is considered non-RAID due to the fact that it neither provides redundancy nor improves performance. Disk spanning is inexpensive, flexible, and easy to implement; however, it does not improve the performance of the drives and any disk failure could result to total data loss.
ASUS GUI RAID Manager: RAID Levels multiple disks. Furthermore, for I/Os that do not span more than one drive, read/writes to different drives can be processed concurrently.
