Appendix C: Using the Adaptec RAID Configuration Utility ● 112 Option Description Backplane Mode ● Series 2, Series 5, Series 6 Controllers: When set to Auto, controller automatically detects backplane signal type: I2C or SGPIO. To set the backplane mode explicitly select SGPIO, I2C, or Disabled. Default is Auto. ● Series 6E/6T Controllers: When set to Default, controller automatically sets the backplane mode to IBPI. To set the backplane mode explicitly, select IBPI, SGPIO, or Disabled. Default is IBPI. Note-With the default IBPI setting, the firmware sends a SGPIO "Backplane_TYPE" signal if it recognizes that a SGPIO Backplane is connected. If any connected SGPIO backplane does not support the "Backplane_TYPE" signal, or it does not support the IBPI protocol, you can manually set the Backplane Mode to "SGPIO". Selectable Performance Mode When set to Dynamic, performance criteria adjusts automatically based on controller usage, RAID level, and disk drive type. When set to OLTP/ Db, performance criteria is optimized for transaction-oriented applications, such as data entry and retrieval. When set to Big Block Bypass, DRAM write cache is bypassed based on IO write size; performance criteria is optimized for serving Web pages, file serving, and data retrieval. Default is Dynamic. Power Management Settings Note: 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. Option Description Power Management Settings When enabled, switches the system to low power state, based on the specified settings. Time Zone The time zone of the place in which the system is located. Time specific power management settings are implemented based on the set time zone. By default, it is set to 00:00. The valid range for the time zone settings is -12:00 to +12:00. Stay Awake Start The time from which the system should operate in the full power mode, irrespective of other power management settings, daily. By default it is set to 00:00. The valid range is 00:00 to 23:59. Stay Awake End The time until which the system should operate in the full power mode, irrespective of other power management settings, daily. By default it is set to 00:00. The valid range is 00:00 to 23:59. Spin Up Limit (Internal) The number of internal drives to be spun up at any given moment. By default it is set to 0. In the default setting, all the internal drives will spin up. Spin Up Limit (External) The number of external drives to be spun up at any given moment. By default it is set to 0. In the default setting, all the external drives will spin up.
