      Table 8-47 Parameters

      Item

      Description

      Strip Size

      Volume of hard drive data on each strip. Options include 64 KB, 128 KB, 256 KB, 512 KB, and 1 MB. The default value is 256 KB.

      The default size is used during RAID configuration.

      Read Policy

      Options for reading data on a virtual drive.

      • Normal: disables the Read Ahead function.
      • Ahead: enables the Read Ahead function. The controller card prefetches sequential data or data to be used and stores it in the cache.
      NOTE:

      To achieve optimal disk performance, set the policy to Ahead for HDDs and Normal for SSDs.

      Write Policy

      Options for writing data on a virtual drive. The write policy of virtual drives varies with the firmware version of the LSI SAS3108 RAID controller card.

      • If the firmware version of the LSI SAS3108 RAID controller card is 4.270.00-4382 or earlier, the following write policies are supported:
        • Write Back: Once all data in the cache is received, the controller card notifies the host that data transmission is complete.
        • Write Through: Once the drive subsystem receives all data, the controller card notifies the host that data transmission is complete.
        • Write Back with BBU: The controller card automatically switches to the Write Through mode when the controller card has no Battery Backup Unit (BBU), the BBU is on charge or discharge, the BBU is faulty, or the Pinned/Preserved cache reaches 50% of the physical cache. It is recommended that you set the write policy to this mode.
      • If the firmware version of the LSI SAS3108 RAID controller card is 4.650.00-6121 or later, the following write policies are supported:
        • Write Back: The controller card automatically switches to the Write Through mode when the controller card has no Battery Backup Unit (BBU), the BBU is on charge or discharge, the BBU is faulty, or the Pinned/Preserved cache reaches 50% of the physical cache. It is recommended that you set the write policy to this mode.
        • Write Through: Once the drive subsystem receives all data, the controller card notifies the host that data transmission is complete.
        • Always Write Back: Once all data in the cache is received, the controller card notifies the host that data transmission is complete.
      NOTE:

      In Always Write Back mode, DDR write data of the controller card will be lost if the supercapacitor is not installed or being charged. This mode is not recommended.

      I/O Policy

      Options for data I/O of special virtual drives. This policy does not affect cache prefetch.

      • Direct:
        • Read scenarios: Data is directly read from hard drives. (If Read Policy is set to Ahead, data is read from the RAID cache.)
        • Write scenarios: Data is written to the RAID cache. (If Write Policy is set to Write Through, data is directly written into hard drives.)
      • Cached: Data is read from or written to the cache. Use this option only when configuring CacheCade 1.1.

      Disk cache Policy

      Cache policy for physical hard drives.

      • Enable: writes data to the cache before writing data to the hard drive. This option improves data write performance, but data may be lost due to power failure without a power failure protection mechanism.
      • Disable: writes data to a hard drive without caching. Data is not lost in the event of power failure.
      • Unchanged: uses the current cache policy.

      Emulation

      Sets the virtual sector size.

      NOTE:

      This parameter is supported only when the firmware version of the LSI SAS3108 is 4.660.00-8102 or later.

      Initialize

      Performs initialization once the RAID array is created. The initialization will damage data stored on RAID member drives.

      [X] is displayed in front of the selected hard drive.

      Configure HotSpare

      Configures hot spare drives for a RAID array.

      [X] is displayed in front of the selected hard drive.

      This parameter is invalid for RAID 0 arrays.
