DescriptionOptionWhen enabled, removable media devices, such as CD drives, are supported. (Thissetting is not available on all RAID controller models.)Removable Media DevicesBoot SupportWhen enabled, the alarm sounds. Default is enabled.Alarm ControlNote: When the alarm is turned off (disabled), it willremain off after a reboot.Sets the default priority for background tasks on the controller (such as logical drivecreation) to High, Medium, or Low. Default is High.Default Background TaskPriorityNote: This setting applies to new tasks. It does not affectcurrently running tasks.When set to Activity and Fault, the drive activity LEDs blink to indicate I/O activity(randomly depending on I/O load) and fault (steady 1Hz). When set to Fault Only,LED Indication Modethe drive activity LEDs blink to indicate fault state only. For Series 6/6E controllers,default is Fault Only.When set to Default, controller automatically sets the backplane mode to IBPI. Toset the backplane mode explicitly, select IBPI, SGPIO, or Disabled. Default is IBPI.Backplane ModeNote: With the default IBPI setting, the firmware sendsa SGPIO "Backplane_TYPE" signal if it recognizes that aSGPIO Backplane is connected. If any connected SGPIObackplane does not support the "Backplane_TYPE" signal,or it does not support the IBPI protocol, you can manuallyset the Backplane Mode to "SGPIO".When set to Dynamic, performance criteria adjusts automatically based on controllerusage, RAID level, and disk drive type. When set to OLTP/Db, performance criteriaSelectable PerformanceModeis optimized for transaction-oriented applications, such as data entry and retrieval.When set to Big Block Bypass, DRAM write cache is bypassed based on I/O writesize; performance criteria is optimized for serving Web pages, file serving, and dataretrieval. When set to User Defined, you are prompted to use the OS tools to setindividual parameters (contact Adaptec support for more information). Default isDynamic.When set to RAID Mode, all RAID functions of the controller are enabled. When setto Auto Volume Mode, RAID functions of the controller are enabled. Attached drivesController Modewithout Adaptec meta-data, but with an OS partition, are surfaced to the hostoperating system as Pass Through devices, where the RAID layer of the controllerfirmware is bypassed when the host issues commands to the device. Attached driveswithout Adaptec meta-data and without OS partitions, are automatically configuredas Simple Volumes. When set to HBA Mode, attached drives are surfaced as PassThrough devices. Changing into HBA mode is allowed only if there are no drives withAdaptec meta-data attached to the controller (see Uninitializing Disk Drives on page74 for more information). Default is RAID Mode.Power Management SettingsNote: When power management is disabled, no related options will be displayed.Note: Make sure the operating system driver supports power management.Note: Default settings are shown in bold type.DescriptionOptionWhen enabled, switches the system to low power state, based on the specifiedsettings.Power ManagementSettings76Proprietary and Confidential to PMC-Sierra, Inc.Document No.: CDP-00277-01-A Rev.
