    Chapter 1 Introduction The AA-3102RS is an Ultra-SCSI to Ultra-SCSI RAID controller specifically designed to provide RAID 0, 1, 3 or 5 capability to any host system equipped with a SCSI interface. It is totally independent of the host system's operating system. All RAID functions are performed by a 486 CPU coupled with high-speed DRAMs and firmware in the Flash Memory.
  • Page 21: Chapter 2 Features

    Chapter 2 Features The AA-3102RS has the following features: Five operating modes: Non-RAID Disk Spanning RAID-0 Disk Striping RAID-1 Disk Mirroring and Striping (RAID 0+1) RAID-3 Disk Striping with Dedicated Parity RAID-5 Multiple Block Striping with Interspersed Parity Comprehensive failure management including:...
  • Page 22 AA-9072UWD: Ultra Wide, differential, 2 SCSI channels AA-9073U2: Ultra2 Wide, 3 SCSI channels Up to 8 logical drives, each with independent RAID modes Up to 8 partitions per logical drive Logical drive can be assigned a name for ease of identification Number of drives for each logical drive has no limitation Dynamic mapping of LUNs to logical drives.

  • Page 25: 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 AA-3102RS RAID controller provides complete RAID functionality and enhanced drive failure management. RAID Management RAID stands for Redundant Array of Inexpensive Drive.

In other words, the capacity of the logical drive is the total capacity of the physical drives.

    JBOD Single Drive Control JBOD 2 GB Minimum Disks Logical Drive required 3 GB Capacity Logical Drive Redundancy 1 GB Logical Drive 2 GB Logical Drive JBOD stands for Just a Bunch of Drives. The controller treats each drive as a stand-alone disk, therefore each drive is an independent logical drive.

    RAID 0 provides the highest performance but no redundancy. Data in the logical drive is striped (distributed) across several physical drives. RAID 1 Disk Mirroring Logical Drive Block 1 Block 2 Block 3 Block 4 Block 5 Block 6 Block 7 Block 8 RAID 1 Disks required...

When a member drive of this specified logical drive fails, the Local member starts to rebuild. Logical Drive Assigns one Local Spare Drive to a logical drive...
  • Page 33 Drive Logical Drive 0 Logical Drive 1 The AA-3102RS RAID controller provides both Local Spare Drive and Global Spare Drive functions. On certain occasions, applying these two functions together will better fit various needs. Take note though that the Local Spare Drive always has higher priority than the Global Spare Drive.
  • Page 34: Identifying Drives

    In the example shown below, the member drives in Logical Drive 0 are 9 GB drives, and the members in Logical Drives 1 and 2 are all 4 GB drives. It is not possible for the 4 GB Global Spare Drive to join Logical Drive 0 because of its insufficient capacity.
  • Page 35 To prevent this from happening, the controller provides an easy way of identifying for the failed drive. That is, the read/write LED of the failed hard drive will light. This LED will prevent you from removing the wrong drive, and is also helpful when locating for a drive. Flash Selected SCSI Drive The Read/Write LED of the drive you selected will light steadily for about one minute.
  • Page 36: Automatic Rebuild And Manual Rebuild

    Automatic Rebuild and Manual Rebuild Automatic Rebuild Local Spare Drive One member drive assigned to this fails in logical drive Global Spare Drive assigned to this manual rebuild When a member drive in the logical drive failed, the controller will first check whether there is a Local Spare Drive assigned to this logical drive.
  • Page 37: Manual Rebuild

    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.
  • Page 38: Concurrent Rebuild In Raid (0+1)

    If neither Local Spare Drive nor Global Spare Drive is available, the controller will detect the SCSI channel and ID of the failed drive. Once the failed drive has been replaced by a new drive/used drive, it starts to rebuild using the replaced drive. If there is no available drive for rebuilding, the controller will not try to rebuild again until the user applies another forced-manual rebuild.
  • Page 39: Disk Array Parameters

    Disk Array Parameters Rebuild Priority Rebuilding time will depend on the capacity of the logical drive. The AA-3102RS RAID controller provides background rebuilding ability. Meaning, the controller is able to serve other I/O requests while rebuilding the logical drives. transparent to the host computer or the operating system.

Each method can be enabled or disabled individually. Hard drives will perform Verify-after-Write according to the selected method. The "Verification on LD Normal Drive Writes"...
  • Page 41: Cache Parameters

    The AA-3102RS RAID controller provides the options to optimize for large-sequential I/O or optimize for small-random I/O access. "Optimization for Sequential I/O" provides larger stripe size (block size, also known as Chunk size) than "Optimization for Random I/O".
  • Page 42: Drive-side Scsi Parameters

    Drive-Side SCSI Parameters SCSI Motor Spin-up When the power supply is unable to provide sufficient current for all the hard drives and controllers that are powered-up at the same time, spinning-up the hard drives serially is one of the best way of consuming lower power-up current.
  • Page 43: Disk Access Delay Time

    When connecting dual host computers to the same SCSI bus, the SCSI bus reset will interrupt all the read/write requests that are being performed. This may cause some operating systems or host computers to act abnormally. Disable the "SCSI Reset at Power-up" to avoid this situation.

    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.
  • Page 46 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. RAID Expansion - Mode 1 RAID 5 Logical Drive - 4GB RAID Expansion...

    This results in a new 4-Gigabyte, RAID 5 logical drive composed of three physical drives. The 4 Gigabytes of increased capacity is in a new partition. 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"...

Follow the directions in Chapter 7 section “Mapping a Logical Drive to a Host LUN” 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.
